Following the Kamoamoa fissure eruption, lava repeatedly erupted within the crater and from the flanks of Pu‘u ‘Ō‘ō. As in episodes 6-10, its lava pond overflowed through a breach in the NE crater wall, forming a vigorous lava river that eventually extended about 6 km before turning from pahoehoe to aa. Lava first reached the ocean on November 28, 1986, after cutting through the coastal community of Kapa‘ahu and covering a section of Highway 130 (within Hawai‘i National Park, the highway is named Chain of Craters road). One of the theories is the hotspot theory put forward by John Tuzo-Wilson, a Canadian geophysicist. In early November 2013, the barely active Peace Day flow stopped as the vent high on the northeast flank of Pu‘u ‘Ō‘ō became inactive? Scientific Event Alert Network Bulletin, vol. Reginald Okamura, a scientist from the Hawaii volcano observatory, said the latest eruption began at 12:30 A.M. today along the east rift zone of Kilauea, which is … (Public domain.). The floor of the crater dropped about 115 meters (377 ft) in just a few hours. Ten days after Kupaianaha stopped erupting, activity returned to Pu‘u ‘Ō‘ō. By 1986, tephra fallout from the fountains built the Pu‘u ‘Ō‘ō cone to a maximum height of 255 m (835 ft) above the pre-1983 surface. Big Island, Hawaii. Smithsonian Institution. Shortly thereafter, new fissures broke open and erupted briefly in and near Nāpau Crater about 4 km uprift of Pu‘u ‘Ō‘ō. Kilauea is estimated to be between 300,000 and 600,000 years old. In late November, a new breakout from the fissure soon diverted all of the lava to the southeast and into the ocean near Kalapana from March 2008 through early 2011. The 16 November 1983 earthquake was highest in magnitude, ground breakage, and structural damage. A massive flood of lava spread rapidly, splitting into two branches—a short northwest branch that stopped the next day and a south branch that reached 3.5 km (2.2 mi) before becoming inactive on August 15. This marked the end of episodic high lava fountains and the beginning of five-and-a-half years of nearly continuous effusion of pāhoehoe lava flows from the new vent. The ocean entries built a series of lava deltas on Kīlauea's southeast coast, which, combined with earlier ocean entries, added a total of about 169 ha (418 acres) of new land to Hawai‘i. Since 1952, Kīlauea has erupted 34 times. Geologic Background. In late 1990, a new lava tube finally diverted lava away from Kalapana and back into Hawai‘i Volcanoes National Park. The Pu‘u ‘Ō‘ō eruption began in 1983, and ranks as the longest and most voluminous known outpouring of lava from Kīlauea Volcano's East Rift Zone in more than 500 years. The eruption began on January 3, 1983, as the first of several fissures broke out on Kīlauea's East Rift Zone. Lava flows to the N, NE, and E originated from Pu'u O, where low fountains played on the S and N rims of the cone and within the breach on its NE flank. View of Pu‘u ‘Ō‘ō's west flank in 1997, after collapse of the crater floor and west rim, Kīlauea Volcano Hawai‘i. Far Reaching Effects of 2018 Kilauea Eruption Earthquakes, ash, and toxic gas can be just as dangerous as the lava spewing from fissures in and around Leilani Estates. The fountains, occurring every 3 to 4 weeks and lasting about a day, fed thick ‘a‘ā flows that buried the surrounding landscape. Kilauea, which overlaps the E flank of the massive Mauna Loa shield volcano, has been Hawaii's most active volcano during historical time. After more than a year of relatively weak activity in Pu‘u ‘Ō‘ō's crater and on the flow field, activity in the crater increased in January 2013. The volume of lava erupted from Kupaianaha steadily declined through 1991 as lava activity in Pu‘u ‘Ō‘ō's crater increased. Lava reappeared in Pu‘u ‘Ō‘ō on July 1, 2007 and came to within 30 m (100 ft) of filling the crater when, on July 21, new fissureserupted on the northeast flank of the cone and extended downrift nearly 3 km (1.9 mi) to the base of Kupaianaha. (Public domain.). Kilauea has experienced a long-term eruption since 1983, though scientists have actually been keeping an eye on the volcano for much longer. The summit crater of Kilauea is located just below the center, and the East Rift Zone occupies the lower left quarter of the image. Since the current eruptive period began in 1983 there have been open lava lakes and flows from the summit caldera and the East Rift Zone. 1983–1986: The Rise of Pu‘u ‘Ö‘ö. Because of growing concern that these flows could reach downslope communities, HVO scientists prepared a new hazard assessment for the eruption. As in episodes 4-10, the growing spatter cone, Pu'u O, located just within Hawaii Volcanoes National Park, was the major eruptive locus. This is a closer view of the leading part of the flow, looking toward Pāhoa Village Road, which cuts across the top of the photo. This fissure sent a flow—the "Peace Day flow," informally named after the United Nations Peace Day holiday—toward Kīlauea's southeast coast once again. Less voluminous flows issued from the S part of the vent and advanced about half the distance to the Royal Gardens subdivision. This flow nearly reached Highway 130, which is the only transit route for nearly 10,000 people living in the lower Puna District. He postulates that the formation of volcanic island chains such as Hawai’i was as a result of the movement of … House burns as lava flows moved into Kalapana, Hawai‘i, in 1990. A N50°E line from the epicenter of the main shock intersects the fissure zone 5 km to the N. The fissure zone, approximately 50-100 m wide, is recognized as a series of en echelon offsets to the left. Kilauea has been erupting nearly constantly since 1983, sometimes explosively, shooting clouds of ash and lava high into the atmosphere, and sometimes effusively, flowing like liquid rock soup. Unlike most volcanoes, the Hawaiian chain sits squarely in the middle of the Pacific plate rather than on a tectonic boundary. Kilauea Volcano | John Seach. Note: Beginning in 1997, HVO's website started documenting the eruption of Pu‘u ‘Ō‘ō in daily to monthly illustrated summaries. Kilauea first emerged from the sea floor aorund 500 000 years ago as the next in the Hawaiian chain of volcanoes. On January 3, 1983, eruptions began on Kilauea’s East Rift Zone creating a 4-mile-long fissure on the Big Island’s southeastern corner. The video starts at 4 am and ends at 11 pm. Within a few months, the eruptions focused on … Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, 2018 lower East Rift Zone Eruption & Summit Collapse, table summarizing Kīlauea activity over the past ~200 years here. Managing Editor: Lindsay McClelland. Scientists divided the eruption into 61 episodes of activity, defined by the style of eruption (for example, discrete lava fountain and fissure events or persistent lava effusion) and location of the erupting vent. In the chronology below, the 61 eruptive episodes are grouped into five broad time periods. About 90% of the surface of the basaltic shield volcano is formed of lava flows less than about 1100 years old; 70% of the volcano's surface is younger than 600 years. But from May to September 2018, Kilauea’s most destructive eruption in recorded history took place. 1 Ongoing eruption, Kilauea Volcano, 1983 - present Eruptions on Hawaiian volcanoes occur at the summit caldera or along one of the two narrow rift zones. Hawaiian Volcanoes Observatory geologist next to cracks on Nohea Street in Leilani Estates. Known as the June 27th flow, it advanced 20 km (12 mi) toward the community of Pāhoa between July and late October 2014. It has been erupting constantly since 1983, according to the United States Geological Survey. During the opening days of the eruption, fissures extended nearly 5 miles (8 kilometers) along Kīlauea’s East Rift Video showing the collapse of the Pu'u 'O 'o crater floor on March 5. The eruption began on January 3, 1983, as the first of several fissures broke out on Kīlauea's East Rift Zone. A lava pond formed above the vent, and frequent overflows built a broad, low shield, later named Kupaianaha, to a height of 56 m (180 ft) in less than a year. 11th and 12 major phases of East Rift Zone eruption. During this time, the massive Pu‘u ‘Ō‘ō cone experienced many collapses that enlarged the crater, lowered the crater rim, and formed many small pits and craters on the flanks of the cone. Lower temperatures, 1,133-1,135°C, were measured at the river's edge. Smithsonian / USGS Weekly Volcanic Activity Report, Eruptions, Earthquakes & Emissions Application. Kilauea's Eruption rate diminished steadily over the first half of the historic period but has been increasing again since 1924. Kilauea's most recent eruption streak started in January 1983, when lava broke out of fissures east of the summit; the lava fountains would eventually form a cone now called Puu Oo. At present, Kilauea volcano is still having one of the most long-lived eruptions known on earth, which started in 1983 on the eastern rift zone and has mainly been concentrated at the Pu'u 'O'o vent. Lava … Two notable rift eruptions were Mauna Ulu (1969-1974) and Pu`u `O`o (1983-present). (Public domain. Since 1952 there have been 34 eruptions and Kilauea has been erupting continually since 1983. The main flow issued through the NE breach, which has been the principal spillway since late July. Between midnight and dawn on 6 November, low fountains were seen from Mountain View, 18 km to the N and from Kalapana, on the coast 14 km to the SE. On April 30, 2018, Pu‘u ‘Ō‘ō's crater floor and lava lake catastrophically collapsed and the eruption ended. 5. The lava lake in Pu‘u ‘Ō‘ō drained, the crater floor dropped about 150 m (500 ft), and a large gap appeared in the west side of the cone. The smoke marks where an active breakout is advancing downslope along the north side of the finger which stalled yesterday after crossing through private property. By the end of episode 11, the river had fed a 9.5 km-long aa flow, the longest in the 1983 eruption, that advanced NE on top of earlier flows from Pu'u O, then extended an additional 4 km through dense rain forest. Volcano Profile |  Over the past 3 decades, about 35 earthquakes of magnitude >= 4 have occurred in the Kaoiki region, two of the largest on 27 June 1962 (M 6.1), and on 30 November 1974 (M 5.5). Tremor peaked between 0530 and 0730 on 30 November with an amplitude more than an order of magnitude above background level. This photo from 6:30 AM, HST, on Wednesday, October 29, 2014, shows lava from the June 27th flow continuing to move downslope through the property it entered the previous morning. Tremor started to decrease rapidly at about 1545 on 1 December, marking the end of the eruptive episode. Vents 100-200 m SW of Pu'u O, in combination with a vent high on the W flank of the cone, produced pahoehoe flows that spread an estimated 1.2 x 106 m3 of new basalt W and S of Pu'u O until the early morning of 7 November, when the W vents stopped erupting. The June 27th flow activity then retreated completely to within about 6 km (4 mi) of Pu‘u ‘Ō‘ō in late March 2015, where it remained for the rest of the year. The intrusion culminated on June 19 with a brief eruption on the east flank of Kāne Nui O Hamo, a lava shield northwest of Pu‘u ‘Ō‘ō. A long-term eruption from the East rift zone that began in 1983 has produced lava flows covering more than 100 km2, destroying nearly 200 houses and adding new coastline to the island. As a result, the floor of Pu‘u ‘Ō‘ō collapsed to form a rubble-filled crater about 80 m (260 ft) deep, which severed the supply of lava to a tube that had been active since 2004. See the table summarizing Kīlauea activity over the past ~200 years here. Ground breakage related to shaking and gravitational adjustments on 16 November occurred along Kaoiki fault scarps and along Kilauea caldera faults. Heliker. A map of locations referred to in the captions. Beginning in 1983, its continuous lava flow served as the island’s primary attraction for visitors. (Public domain.). This is because magma moves upwards from a shallow magma chamber (3-4 km below the summit caldera) or forces itself laterally along deep cracks and fissures that form the rift zones. Report on Kilauea (United States) (McClelland, L., ed.). "Lava apparently first reached the surface within the crater of Pu'u O at 1600 on 29 November, when an electric trip wire within the crater was cut. Scientific Event Alert Network Bulletin, 8:11. Visible fountains and audible roar from the vent were first reported at about 0450. It has been erupting continuously since 1983. In 1963, J. Tuzo Wilson proposed the “hotspot theory” to explain this unusual placement. By June 1983, the eruption became focused at a single vent, and over the next 3 years, a series of 44 lava fountains built a cinder-and-spatter cone later named Pu‘u ‘Ō‘ō. "Pu'u O was the major locus of lava production. In November 2014, the flow front began to advance again in a slightly different direction, and by mid-December 2014, was threatening the Pahoa Marketplace. The nearly continuous, quiet effusion of pāhoehoe lavafrom different flank vents over the next 15 years substantially widened the existing flow field and sent flows into the ocean most of the time. Kilauea is an active volcano, and the most active of the five volcanoes. Lava stopped filling the crater on September 21, when a new fissure erupted high on the northeast flank of Pu‘u ‘Ō‘ō. These fissures led to the shutdown of the Kahauale‘a flows and the start of a new lava flow that rapidly advanced to the east. Lava fountains and flows have profoundly altered the landscape and repeatedly challenged residents with lava inundation. From 1955 to the present Kilauea has seen mostly East Rift Zone activity interspersed with small summit eruptions. 4. Kilauea has been erupting since 1983 — can scientists predict when it will stop? View of Pu‘u ‘Ō‘ō's west flank in 1992, and shield growing at base of cone, Kīlauea Volcano Hawai‘i. Geologists have dated and documented dozens of major eruptions over the volcano's long history, bridging the long gap between Kīlauea's oldest known rock and only extremely recent written records and historical observation. 16 November earthquake - repose period activity. New fissures erupted on the east flank of Pu‘u ‘Ō‘ō on June 27, 2014. Narrative of the Kilauea East Rift eruption, 1983-1993, by C.C. An electric trip wire, installed within the crater of Pu'u O to monitor the first appearance of lava, was broken between 2350 on 5 November, and 0000 on 6 November. Over 800 of these, ranging in magnitude from about 1.0-4.3, were selected for processing by computer for location and magnitude. D ozens of earthquakes shook Hawaii’s Kilauea Volcano Wednesday, as scientists warned of a possible eruption following the collapse of the crater floor at the Puu Oo vent. The eruption entered its most destructive period in March 1990, when breakouts from a lava tube progressively entered the Kalapana community, an area cherished for historic sites and black sand beaches. "Between episodes 11 and 12, low-level harmonic tremor typical of repose periods persisted in the eruption zone. About 50 aftershocks were greater than magnitude 3.0, and 3 were over magnitude 4.0. "Harmonic tremor amplitude, sustained during the eruption at a level comparable to that of recent previous episodes, dropped rapidly between 1840 and 1850 on 7 November, at the end of the eruption. Activity at Kilauea remains at very low levels, with no eruptions anywhere on the volcano, as has been the case since early September. Firstly with the eruption of Pu oo oo vent and now from the Kamoamoa Fissure which erupted in March 2011 generating 2.5million cubic mets of lava/day. The entire event was over in 24 hours. Hawaii's governor has already declared a state of emergency to open up more resources for the response. ), Kupaianaha vent forms perched lava pond 3 km (1.9 mi) east of Pu‘u ‘Ō‘ō (cone in background). https://doi.org/10.5479/si.GVP.SEAN198311-332010. On August 3, 2011, the crater floor suddenly collapsed as lava burst through the west flank of the Pu‘u ‘Ō‘ō cone. Information Contacts: E. Wolfe, A. Okamura, and R. Koyanagi, HVO. It is located along Hawaii's south shore, and is believed to have reached sea level approximately 100,000 years ago. A 12-day pause in the eruption followed. On Jan. 3, 1983, superheated gas and magma drilled through thick piles of ancient lava in Hawaii, forcing open a 4-mile-long (6.4 kilometers) fissure in Kilauea volcano's east rift zone. Copious hot oxidized fume issued continuously from Pu'u O, maintaining incandescence in numerous openings. The flow briefly entered the ocean in December 2011, and subsequent breakouts entered the sea between November 2012 and August 2013. This filling and other evidence indicated that the magma system extending from Kīlauea's summit reservoir to Pu‘u ‘Ō‘ō was increasingly pressurized. These lavas exhibit form… The faulting was a probable result of compressional stresses within the crust induced by magmatic activity generating lateral tensions from Mauna Loa and Kilauea. Kilauea volcano is near-constantly erupting from vents either on its summit (caldera) or on the rift zones. "The 11th and 12th eruptive episodes occurred on 6-7 November and 29 November-1 December. Lava cascades out of perched lava channel into lower channel, Pu‘u ‘Ō‘ō in background, Kīlauea Volcano, Hawai‘i. For the next 10 years, lava variously appeared in Pu‘u ‘Ō‘ō, sometimes overflowing its crater rim, and erupted from new flank vents for several months to a few years at a time. Landslides and rockfalls occurred on the steep caldera and crater walls, and on the (Hilina) escarpments on Kilauea's S flank. The current eruption of Kilauea on the east rift zone is called the Pu`u `O`o Eruption. Thus far, 15-20 cm of southward extension has been measured on some E-W-trending extension cracks. Kilauea (United States) 11th and 12 major phases of East Rift Zone eruption. More information about the end of this eruption can be read in the January 31, 2019 issue of Volcano Watch. Heliker. (Public domain.). View of Pu‘u ‘Ō‘ō's west flank in 1999, after crater overflows, continued growth of shield, and collapse of 1997 spatter cone, Kīlauea Volcano Hawai‘i. (Public domain.). This eruption lasted five days. All of the fountains were relatively low. Eruptions are prominent in Polynesian legends; written documentation extending back to only 1820 records frequent summit and flank lava flow eruptions that were interspersed with periods of long-term lava lake activity that lasted until 1924 at Halemaumau crater, within the summit caldera. Neither the tremor nor the fume production changed recognizably in response to the 16 November earthquake. The increase accelerated in the next few hours, and at 0447 on 30 November, a sharp increase was recorded, apparently marking the start of major lava emission. Among them, Kilauea holds the Guinness World Record for being the most active volcano on the planet. By the end of the eruption in 2018, lava flows had covered 144 km2 (55.6 mi2), erupted about 4.4 km3 (1.1 mi3) of lava, and had added 177 hectares (439 acres) of new land to Kīlauea's southeastern shore. The NE-trending nodal plane with a right lateral strike-slip motion is preferred on the basis of aftershock distribution of past events. "During the 43 hours of eruption, approximately 12.1 x 106 m3 of lava was extruded, 85% in the long flow to the NE. In a series of eruptions that began in 1983 and continued into the early 21st century, Kilauea produced a river of flowing lava that reached the sea 10 miles (16 km) south of the volcano. By June 1983, the eruption became focused at a single vent, and over the next 3 years, a series of 44 lava fountains built a cinder-and-spatter cone later named Pu‘u ‘Ō‘ō. The eruption began on January 3, 1983, as the first of several fissures broke out on Kīlauea's East Rift Zone. Lava reappeared in the crater on March 26, 2011, and a perched lava lake quickly grew as the crater refilled. Lava from the eruption has burned structures and buried roads, but there has been little loss of life as a result of Kilauea's eruption. Abston, with captions by T.J. Takahashi and C.C. Lava temperatures, measured by thermocouple in pahoehoe toes in flows from the W vents and in sustained overflows from the lava river, ranged from 1,141 to 1,144°C. Lava reappeared in Pu‘u ‘Ō‘ō within days of the August 3 breakout, and the crater again filled unusually fast. Commonly, a series of rootless shields formed along the lava tube systems, some of which merged to build a broad ridge 2 km (1.2 mi) long in the middle of the flow field. Complete Bulletin. The volcano has been in constant eruption since 1983. By early March 2011, lava had filled the crater to within about 20 m (65 ft) of its northeast rim. 16 November earthquake - repose period activity. Please cite this report as: Faint glow in the eruptive zone was first reported at 2300. U.S. Geological Survey (Public domain). (Public domain.). By September 10, lavaoverflowed both the northeast and southwest rims of the crater. "Unlike most of the previous eruptive episodes at Pu'u O, when vigorous lava production was preceded by several hours to several days of low-level activity within the crater, episode 11 began quickly. The largest collapse occurred on the night of January 30, 1997, when the magma conduit between the summit and Pu‘u ‘Ō‘ō ruptured, cutting off the supply of magma to the eruption. A long-term eruption from the East rift zone that began in 1983 has produced lava flows covering more than 100 km2, destroying nearly 200 houses and adding new coastline to the island. (Public domain.). (Public domain.). The 1984 eruption of Mauna Loa was a Hawaiian eruption in the U.S. state of Hawaii that lasted from March 25 to April 15, 1984. By 0010, glow from the eruption was visible 20 km away at HVO. Harmonic tremor in the eruptive zone began to increase above normal repose-period background levels at 2314 on 5 November and reached a maximum amplitude at 0025 on 6 November. January 2012 marks the 100th anniversary of the Hawaiian Volcano Observatory, which stands watch over one of our planet’s most active volcanoes. From 1983 to 2018 eruptive activity was nearly continuous along the volcano's East Rift Zone. Lavathen erupted from a fissure on Pu‘u ‘Ō‘ō's west flank, the first of many flank vents that soon built a broad shield 130 m (425 ft) tall on the southwest side of the cone. Focal depths are concentrated at about 10 km. Information Contacts: E. Wolfe, A. Okamura, and R. Koyanagi, HVO. Those NE and SW of Pu'u O were about 10-20 m high. Lava flows also destroyed 215 structures and buried 14.3 km (8.9 mi) of highway with lava as thick as 35 m (115 ft). 11 (November 1983) Most of the major flows on Kilauea Volcano have been roughly dated using Carbon 14. As of Wednesday morning at 7 AM, the flow was 240 m (260 yd) straight-line distance from Pāhoa Village Road. "The earthquake was 12 km deep, and a preliminary first motion analysis from local seismic data indicates a strike-slip mechanism. "Episode 12 began in earnest at 0447 on 30 November, and continued until 1545 on 1 December. The east rift is historically the more active of the two, most recently erupting from January 1983 to August 2018. Global Volcanism Program, 1983. Lava erupted again in the Pu‘u ‘Ō‘ō crater on February 24, 1997, and within a month, lavaerupted outside the crater from new vents on the west and southwest flanks of the cone. It started in Jan. 1983 and reached it 35th year of activity on 3 January 2018! Kilauea is still active. The oldest flows, dating back 275,000 to 225,000 years, have been recovered from Kīlauea's submerged southern slope by ship-towed remotely operated vehicles. The deflationary tilt change of about 19 µrad at Uwekahuna corresponds with a summit volume loss of about 8 x 106 m3. In hand-lens view, the basalt is sparsely porphyritic with scattered olivine phenocrysts up to about 2 mm in diameter. On June 17, 2007, an intrusion of magmainto Kīlauea's upper East Rift Zone depressurized the magma reservoir beneath Pu‘u ‘Ō‘ō. The earthquake, however, produced a major perturbation in the record of Kilauea summit tilt (figure 23). As new fissures erupted between Pu‘u ‘Ō‘ō and Kupaianaha for about 3 weeks in November, lava output from Kupaianaha continued to decline until it stopped on February 7, 1992. A 4.7 km-long zone of E-W-trending tension fissures has been identified as the possible main surface rupture. 3. Seismicity and deformation are at background levels, and interestingly, the Hawaiian Volcano Observatory reports that total gas emissions across the volcano are at their lowest levels since before the start of the long-term Pu'u O'o eruption in 1983. On January 19, lava spilled from a lava pond that had built a small shield above the north crater rim, spreading flows down Pu‘u ‘Ō‘ō's northeast flank as far as 8 km (5 mi). In 1986, the eruption shifted 3 km (1.8 mi) to the northeast along Kīlauea's East Rift Zone. Aerial view of the 2011 Kamoamoa lava fountains looking northeast toward Pu‘u ‘Ō‘ō, in the background. Lava fountain erupts from Pu‘u ‘Ō‘ō, Kīlauea Volcano, Hawai‘i. The new vent cut the lava supply to the June 27th flow, which became inactive by June 8. Kilauea's most recent eruption streak started in January 1983, when lava broke out of fissures east of the summit; the lava fountains would eventually form a cone now called Puu Oo. Activity soon focused over a single fissure and produced a series of ‘a‘ā flows that reached as far as 6 km (4 mi) to the northeast. Advancing 8 km during the eruption, the front covered 1977 lavas S of the main episode 11 flow. The 3 x 5 km caldera was formed in several stages about 1500 years ago and during the 18th century; eruptions have also originated from the lengthy East and SW rift zones, which extend to the sea on both sides of the volcano. Preliminary determinations of hypocenters during the initial 10 hours of aftershock activity indicate an epicentral zone about 20 km in diameter centered between the summit areas of Mauna Loa and Kilauea. 19.425 N, 155.292 W, summit elevation 1222 m Shield volcano. "When the first observers arrived at 0730, discontinuous low fountains played along a 700-m line approximately centered on Pu'u O. "At 061301 on 16 November, a magnitude 6.7 earthquake occurred in the Kaoiki region (figure 22) between Mauna Loa and Kilauea, an area of persistently high seismicity.
