6.0 magnitude earthquake 172 km from Prudhoe Bay, Alaska, United States

USGS page: M 6.0 - 65km SSW of Kaktovik, Alaska

USGS status: Reviewed by a seismologist

Reports from the public: 17 people

6.0 magnitude, 11 km depth

Comment: This latest quake comes less than 24 hours after a magnitude 6.4 event struck the same area - the strongest ever to hit the region:
Alaska's North Slope was hit Sunday by the most powerful earthquake ever recorded in the region, the state's seismologist says. At 6:58am Sunday, the magnitude 6.4 earthquake struck an area 42 miles east of Kavik River Camp and 343 miles northeast of Fairbanks, the state's second-biggest city, the AP reports. The US Geological Survey says the earthquake had a depth of about 6 miles. State seismologist Mike West tells the Anchorage Daily News that the earthquake was the biggest recorded in the North Slope by a substantial amount. "This is a very significant event that will take us some time to understand," he says.

The previous most powerful quake in the North Slope was in 1995 at magnitude 5.2, West says. The jump from a 5.2 to Sunday's 6.4 is significant because earthquakes rapidly grow in strength as magnitude rises, he says. A magnitude 6.4 earthquake is 15.8 times bigger and 63.1 times stronger than a 5.2 earthquake, according to the US Geological Survey. "That's why at 6.4 this changes how we think about the region," West says "It's a little early to say how, but it's safe to say this earthquake will cause a re-evaluation of the seismic potential of that area." Later Sunday, another magnitude 6.1 earthquake hit at 1:15pm near the city of Kaktovik on Alaska's North Slope, the US Geological Survey says.

Motorists ride past buildings ruined by Sunday's earthquake in Pamenang, Lombok Island, Indonesia, Friday, Aug. 10, 2018. The north of the popular resort island has been devastated by Sunday's earthquake, damaging thousands of buildings and killing a large number of people.
Scientists say the powerful Indonesian earthquake that killed nearly 400 people lifted the island it struck by as much as 25 centimeters (10 inches).

The National Disaster Mitigation Agency said on Saturday that 387 people died, jumping from the 321 it reported the previous day, as search and rescue teams continued to sift through the rubble and people already buried by relatives are accounted for.

Using satellite images of Lombok from the days following the Aug. 5 quake, scientists from NASA and the California Institute of Technology's joint rapid imaging project made a ground deformation map and measured changes in the island's surface.

In the northwest of the island near the epicenter, the rupturing faultline lifted the earth by a quarter of a meter. In other places it dropped by 5-15 centimeters (2-6 inches).

Shallow M6.4 earthquake hits northern Alaska - 47 quakes in the last 24 hours

alaska quake august 2018
A strong and very shallow earthquake registered by the USGS as M6.4 hit northern Alaska at 14:58 UTC (06:58 local time) on August 12, 2018. The agency is reporting a depth of 9.9 km (6.1 miles). This earthquake can have a low humanitarian impact based on the magnitude and the affected population and their vulnerability. EMSC is reporting Mw6.1 at a depth of 10 km (6.2 miles).

The epicenter was located 60.9 km (37.8 miles) SW of Elupak and 564.3 km (350.6 miles) NNE of College (population 12 964).

There are about 300 people living within 100 km (62 miles).

Comment: There have been 47 quakes in the area in the last 24 hours. And this surge in activity is evident all over the planet: Also check out SOTTs monthly documentary: SOTT Earth Changes Summary - July 2018: Extreme Weather, Planetary Upheaval, Meteor Fireballs

Nearly two dozen earthquakes at the gigantic Katla volcano in Iceland

Katla, a giant volcano hidden beneath the ice cap of Mýrdalsjokull glacier in South Iceland, which towers over the town of Vik, has been relatively calm and quiet for several months, following growing signs of activity in the past couple of years.

Seismic activity in Katla is taken very seriously, as the volcano is under close supervision, as the volcano has erupted very regularly every 60-80 years.

The last eruption took place in 1918, making Katla long overdue for an eruption.

Latest quake of magnitude 6.2 reportedly collapses buildings as search in rubble continues following Sunday's disaster

An earthquake with a magnitude of 6.2 hit Indonesia's Lombok island on Thursday, less than a week after a 6.9-magnitude tremor that is believed to have killed more than 300 people.

Thursday's earthquake struck just after midday, sending panicked residents into the streets. According to information from Indonesia's meteorology agency the epicentre of the quake was 6km north-west of the island with a depth of 12 meters.

Sutopo Purwo Nugroho, the spokesman for the national disaster agency, said that there was "public panic" on Thursday as people ran from their homes as they felt the latest tremor. "The public are still traumatised by the quake before," he said. Initial footage posted by Sutopo on Twiter showed indications of further damage to buildings and power lines.

The death toll for Sunday's earthquake is still climbing and unclear. Officials and organisations including the military, the governor of the province that includes Lombok, the national search and rescue agency and the regent of North Lombok have issued different death tolls, ranging from 226 to 381.

The government-run news agency Antara put the death toll for Sunday's tremor at 347. The number of the dead may still climb higher, as rescuers work to free people trapped in the rubble.

The death toll rose to 39 after a magnitude 7.0 earthquake rocked the Indonesian island of Lombok and nearby Bali on Sunday, damaging buildings, sending terrified residents and tourists running into the streets and triggering a brief tsunami warning.

The head of disaster management in Indonesia's West Nusa Tenggara province, Muhammad Rum, announced the death toll - which could rise further as search and rescue operations continue.

Social media posts from the scene showed debris piled on streets and sidewalks. Hospital patients, many still in their beds, were rolled out onto streets as a safeguard against structural damage to the hospital buildings.

"Back in the house now. That was an attention getter," tweeted @Bali_chris. "Strongest quake we've felt in the 13 years we've been here. Much stronger than the last one in Lombok that we felt in Bali. Hope everyone in Lombok is safe."


Comment: Earthquake Track relays information stating that it occurred at a shallow depth of 10kms.

UPDATE: The Daily Star (UK) on July 6th reports:
A MASSIVE 7.0 magnitude earthquake has killed at least 91 people after rocking the Indonesian island of Bali, sparking fears of a tsunami.

The powerful quake is 7.0 on the Richter scale - prompting terrified holidaymakers at the tourist hotspot to scramble for safety.

Model Chrissy Teigen, who is on holiday on the island with husband John Legend, told her 10.6million Twitter fans how she walked outside naked clutching her newborn baby Miles as the tremor hit.

She tweeted: "Bali. Trembling. So long.

"MASSIVE earthquake."

"It felt like a ride. 15 solid seconds of "hooooooly s**t this is happening."

"I very calmly walked outside saying clutching baby saying 'I'm naked. I'm naked. I'm naked' like a naked zombie".

Shallow magnitude 5.9 earthquake strikes Iranian Kurdish region, injures 25

EARTHQUAKE
A magnitude 5.9 earthquake hit the western Iranian province of Kermanshah (Kermanshan) on Sunday, wounding at least 25 people, a few hours after two quakes struck the Hormozgen province in the south of the country, state media reported.

"Up to now, we have had reports of 25 injured and fortunately no fatalities," Houshang Bazvand, Governor of Kermanshah, told Iranian state media, adding that the injuries sustained were not severe enough to require hospitalization.

Local reports also noted that the two other quakes, with magnitudes of 4.7 and 5.7, had damaged buildings in a few villages without causing casualties.

The Kermanshan quake, which hit near the border with Iraq, was felt throughout different cities in the Kurdistan Region, including Halabja, Sulaimani, Erbil, Soran, and the Raparrin areas.

Comment: The Associated Press reports that the series of 3 quakes were all at a shallow depth of under 10kms (and therefore more likely to cause structural damage to buildings).
