A Tiny Leak Led to a Massive, Unexpected Collapse at Kilauea Volcano
Its caldera’s dramatic, surprisingly slow collapse could point to other risks worldwide

By Stephanie Pappas on December 5, 2019

The 2018 eruption of Kilauea in Hawaii featured the spectacular collapse of the volcano’s caldera, creating a hole nearly as deep as One World Trade Center in New York City is tall at its summit. Now new research finds that this dramatic change was triggered by only a small leak of magma from the reservoir beneath the peak.

:snippity:

Kilauea is a 1,250-meter-tall, broad shield volcano on the southeastern coast of Hawaii’s Big Island. In 1983 it began belching lava from its Eastern Rift Zone, an area fractured by fissures created as gravity pulls the entire area downward, toward the sea. That eruption culminated furiously in May 2018, when the lava lake within the caldera, or crater, at the volcano’s summit began to drain like a bucket with a hole in it. Simultaneously, the lower part of the Eastern Rift Zone came alive with lava fountains and new fissures, one of which spouted a river of lava that flowed through residential neighborhoods and into the sea. More than 700 homes and other buildings were destroyed before the eruption stopped in August 2018.

The disaster took place under the watchful eyes of more scientific equipment—including drones, GPS sensors, thermal cameras and satellite-based radar—than any caldera-collapse eruption in history. “Some of the detail you get from Kilauea is unlike anything we’ve seen before,” Gudmundsson says.

In three separate papers published this week in Science, researchers wove together much of the data from those instruments to tell the tale of Kilauea’s eruption from summit to sea. The first revelation, discovered in a study led by U.S. Geological Survey geophysicist Kyle Anderson, was that the eruption caused the caldera collapse rather than the other way around. That relationship had been a geologic chicken-and-egg question debated among scientists, but at both Bardarbunga and Kilauea, the eruption clearly came first. Anderson and his team found that the rifting of the island, which occurs as gravity drags the slope of Kilauea seaward, opened up fissures for magma to drain from the volcano’s reservoir and the lava lake above it. When the magma below the caldera disappeared, all the rock in its floor crumbled down more than 500 meters over an area of five square kilometers. Once the caldera floor buckled, it pressurized the whole underground magma plumbing system like a piston—increasing and prolonging the eruptive activity in the rift zone.

New Zealand's Whakaari/White Island victims are all covered by state compensation. Here's why

Key points:
•All victims of the White Island disaster will be eligible for compensation from NZ's public insurance body
•Critics of NZ's no-fault compensation scheme say it leads to more risk taking
•Proponents of the scheme say it improves continuity of care


In New Zealand, everyone's covered by public indemnity insurance.

That means both residents and visitors can apply for compensation if they suffer accidents while at work, on a holiday, or even in a major tragedy such as a terrorist incident or natural disaster.

Legally, this means anyone who suffers an injury on New Zealand soil does not have to take someone through the courts to prove they were at fault in order to obtain monetary compensation.

All they need to do is submit their claim to the country's public indemnity insurance provider, the Accident Compensation Corporation (ACC), to receive compensation for their injuries — be they mental or physical.

5.8-magnitude quake strikes Puerto Rico, damage reported

SAN JUAN, Puerto Rico (AP) — A 5.8-magnitude quake hit Puerto Rico before dawn Monday, unleashing small landslides, causing power outages and severely cracking some homes. It was one of the strongest quakes yet to hit the U.S. territory that has been shaking for the past week.

The quake struck at 6:32 a.m. (1032 GMT) just south of the island at a relatively shallow depth of 10 kilometers (6 miles), according to the U.S. Geological Service. There was no tsunami threat, officials said.

Power outages were reported in some parts of Puerto Rico following the quake, Angel Vazquez, emergency management director for the southern coastal city of Ponce, told The Associated Press.

“This is one of the strongest quakes to date since it started shaking on Dec. 28,” he said. “It lasted a long time.”

New York Times
Warnings of ‘Volcanic Tsunami’ After Eruption in the Philippines

Hundreds were evacuated and tremors were felt in nearby villages amid an eruption of the country’s second-most-active volcano, the Taal, about 40 miles from Manila.



MANILA — A dramatic explosion of the Philippines’ second-most-active volcano on Sunday prompted warnings of a possible “volcanic tsunami” as villagers were evacuated and nearby communities were advised to take precautions against any lake water surges.

The explosion, which sent a plume of ash half a mile into the air, came months after the volcano — Taal, about 40 miles south of Manila — began exhibiting a state of unrest. Tremors were felt on the volcano’s island and in villages around the nearby town of Agoncillo in Batangas Province, and booming noises from the volcano raised fears among residents.

“The earthquakes were strong, and it felt like there was a monster coming out” as in the movies, said Cookie Siscar, who had left the area and was relaying a report from her husband, Emer, a poultry farmer, who was in their home in Batangas that overlooks the volcano island.

The Philippine Institute of Volcanology and Seismology raised its alert level for Taal Volcano to four out of five, indicating that a “hazardous eruption” was imminent.

The U.S. Geological Survey said a magnitude 4.5 earthquake struck about 2 miles (3 kilometers) southwest of Hutchinson shortly after 1 p.m. The service had initially reported that it was a magnitude 4.4 earthquake, but later upgraded it. No damage was immediately reported.

Kansas began seeing a spike in earthquakes in 2014 that were blamed on wastewater injection wells from oil and gas production. The number of quakes began tampering off after oil prices dropped and regulations were enacted.

Multiple fatalities after earthquake hits eastern Turkey

Officials confirm 18 people killed as rescue teams works to free trapped survivors


An earthquake with a magnitude of 6.8 has killed at least 18 people in eastern Turkey.

More than 500 have been left injured and several are trapped in the wreckage of toppled buildings. Rescue teams from neighbouring provinces were dispatched to the affected areas, working in the dark with floodlights, and defence minister Hulusi Akar said troops were on standby to help.

TV footage showed rescuers pull out one injured person from the rubble of a collapsed building in the eastern Elâzığ province. At least three people were believed to be trapped in a building in the area, where officials said four or five structures were toppled, including one at least four stories high. ...

The quake struck at 8.55pm local time, 5.55pm GMT, at a depth of 6.7km near the town of Sivrice, the Disaster and Emergency Management Presidency (AFAD) said. It was followed by several aftershocks, the strongest with magnitudes 5.4 and 5.1.

Over 1,000 buildings collapse after earthquake hits Turkey-Iran border

https://www.theweathernetwork.com/ca/ne ... ran-border
Nine people died and hundreds of buildings collapsed in southeastern Turkey on Sunday after a magnitude-5.7 earthquake struck near the border with Iran, injuring dozens in villages and towns in both countries, government officials said.

Three of those killed were children and 37 Turks were injured, including nine critically, Turkey's health ministry said.

The shallow tremor caused more than 1,000 buildings to collapse in Turkey, prompting a brief rescue effort to find those trapped under rubble.

The quake damaged buildings some 90 km (56 miles) to the west in the Turkish city of Van, and to the east in dozens of villages in Iran, where state TV said 75 people were injured including six in hospital, though there were no fatalities.
