Minor steam-and-gas emissions rose from a cluster of fumarolic vents located on the W shore of the lake; there has been no evidence of ash in the emissions. The discharge rates of the emissions during the year were characterized by low-to-moderate levels which were typical. Temperatures at the larger vents generally declined. The level of the lake had dropped, isolating a small pool from the main body of the lake. The Volcanic Alert Level remained at 2 on a scale of and the Aviation Color Code remained at Yellow the second level on a four-color scale.

At least four people were killed, some were injured, and some remain possibly missing in Tonga from tsunami waves up to 20 m 66 ft high. Tsunami waves with run-up heights up to 45 m ft struck the uninhabited island of Tofua. Two people drowned in Peru when 2 m 6 ft 7 in waves struck the coast. It was the largest volcanic eruption since the eruption of Mount Pinatubo. It is thought that in recent centuries, only the Krakatoa eruption of rivalled the atmospheric disturbance produced. On 22 and 23 December , 8-tokilometre-high 5. Surtseyan explosions , steam plumes and steam bursts were recorded by a Tonga Navy crew on 23 December , during which time the first ground-based images of the eruption were created. Between 24 and 27 December , steam and gas emissions reached altitudes of Ash plumes reached heights of only 3 km 1. Eruption plumes during the second half of December interrupted air travel to Tonga multiple times. As activity on the island decreased, it was declared dormant by the Tonga Geological Services on 11 January The explosion was heard in Samoa , roughly km mi away before the sound travelled to more distant countries. Low-frequency noise persisted for approximately two hours. The volcanic explosion caused atmospheric shockwaves to propagate around the globe. Satellites visually captured shockwaves propagating across the Pacific Ocean and a very wide eruption column.

A new report has revealed Tonga's underwater volcano disaster triggered waves up to 90 metres high. The report's authors said their simulated peak height of the largest blast, number five in the sequence, was 85 metres. One of the co-authors, Auckland University professor Shane Cronin, said the findings increasingly showed what a monumental event the eruption was.

New Zealand raises volcano alert level for Lake Taupo after small earthquakes are detected. For the latest, search on ABC Emergency. New Zealand scientists have increased the alert level for a volcano below the country's biggest lake, which caused the largest eruption on Earth in the past 5, years when it last exploded about 1, years ago. In a statement, geological agency GeoNet said it had detected almost small earthquakes below Lake Taupo, the caldera created by the giant volcano, and had raised the volcanic alert level to 1 — minor volcanic unrest — from 0. The volcanic alert system is based on six escalating levels, but GeoNet notes that eruptions may occur at any level, and levels may not move in sequence as activity can change rapidly. The Taupo volcano spewed more than cubic kilometres of material into the atmosphere when it last erupted around AD, devastating a large area of New Zealand's central North Island in a period before human habitation. GeoNet says the eruption was the largest on the planet in the past 5, years. The agency added while it was the first time it had raised the Taupo Volcano alert level to 1, it was not the first time there had been activity, and said the chance of an eruption remained very low. New Zealand straddles the boundary between the Pacific and Australian tectonic plates and experiences significant volcanism and earthquakes.

The charges were laid in the wake of a fatal volcanic eruption on Whakaari White Island, a popular tourist destination, that killed 22 people and injured 25 others. Reprints and permissions.

Adams reported a dark, pulsating tephra column that rose intermittently from White Island to about 1 km altitude. Perhaps the most astonishing phenomenon of the Hunga Tonga-Hunga Ha'apai volcano was not the nature of eruption, but the remarkably low casualty rate of the disaster. Shockwaves from the eruption caused abnormally high waves along the coasts of Peru and Japan. The situation is similar to that in prior to the eruption of Rudolf, and a phreatic eruption could occur in the next few months. A 2-km-high cloud was seen during the late afternoon of 7 January, followed by 7 more large clouds in the next 35 minutes. Satellite animation of the initial ash plume and shockwave on 15 January A glow had been observed during an 11 March overflight, but could not be confirmed on 25 March because of the large quantity of gas filling the crater. Bibcode : GGG Between 27 February and 2 March, the seismograph recorded periods 45 minutes to 6 hours of semi-continuous Hz vibration and several low-frequency, probable B-type shocks.

Researchers develop system to track shaking within volcanoes that could provide up to 4 days notice of an eruption.

Retrieved 16 January — via Twitter. A comparison of 25 March airphotos with 4 April ground observations indicated that there had been no eruption of large ejecta since 25 March. During overflights of the island on 15 and 20 July scientists observed minor steam-and-gas activity around the Primary Crater lava domes and noted that the Main Crater area continues to fill with water. Tags: Tonga. Pure and Applied Geophysics. Several streams of water were visible on the crater floor and a particularly vigorous spring emerged at the base of the E crater wall. The brief period of increased activity was likely caused by a series of low-energy subterranean explosions, similar to activity observed in mid-February and early-mid March. During the previous week scientists visited the island and detected continuing over the previous three months ground deformation and a small increase in CO2 soil gas flux. A lengthy trial for Whakaari Management Limited WML , a firm co-directed by the three brothers who own the active volcano off the east coast of the North Island, concluded in the Auckland district court on Thursday. In the Sendai Port, the tsunami measured 0. Retrieved 30 January Hawaii News Now. Bombs up to 1 m in diameter were infrequently thrown above the vent, breaking open to reveal incandescent interiors. They noted that the most likely cause was a small amount of magma moving into the shallow part of the volcano. Archived from the original on 16 January
