This week in volcano news - Canary Islands earthquake swarm - Mount Ibu erupts

Ibu volcano
Ibu volcano
In the last week, an earthquake swam began underneath the dangerous Mount Teide volcano in the Spanish Canary Islands. In only 24 hours, it produced the number of earthquakes typically seen in 6 months at the volcano. Meanwhile in Indonesia, the Ibu volcano produced an unusually large explosion on June 6th. Since then, its eruptive intensity has remained above normal. And, in Alaska, the Davidof volcano experienced a major earthquake which resulted in potentially secondary volcanic earthquakes. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.

This week in volcano news: Mount Bulusan erupts - Danger at Mount Awu

Mount Bulusan
Mount Bulusan
In the last week, Mount Bulusan in the Philippines unexpectedly erupted, sending a plume of ash to 2,743 meters or 9,000 feet. Numerous volcano tectonic earthquakes have since occurred underneath its summit, meaning that it is likely to erupt again. Meanwhile, in Indonesia, there is now a greatly increased chance that Mount Awu will erupt in the next several weeks due to the detection of harmonic tremor underneath its edifice. And, in Russia, a volcano known for containing one of the planet's rarest minerals unexpectedly began showing signs of unrest through increased sulfur dioxide emissions.

This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.

Magnitude 6.3 earthquake off Rat Islands, Alaska - 3rd major quake within 11 hours

MAPP
A magnitude 6.3 earthquake was recorded at 3:38 p.m. Saturday about nine miles south of Davidof Island in the western Aleutians. Since that first quake, there have been five additional earthquakes in the area measuring a magnitude 2.9 and higher as of 7 p.m. Saturday.

Stephen Holtkamp, duty seismologist with the Alaska Earthquake Information Center, says this is a pretty typical sequence for this region.

"We can expect the aftershock sequence to continue for a few days," said Holtkamp. He also said there is a low chance, about 3 to 5 percent, of a larger earthquake happening in the same area.

There has been no tsunami risk with these earthquakes. Holtkamp says these earthquakes are too deep to create a tsunami. "In order for a tsunami to be generated, it (an earthquake) needs to move the sea floor up and down," said Holtkamp. "There's 65 miles of rock between where the earthquake happened and the water," Holtkamp said.

Davidof Island is in the Rat Islands. The first quake was recorded 36 miles southeast of Kiska Volcano and 55 miles west of Semisopochnoi Island.

Strong magnitude 6.2 earthquake at 238 km depth

A magnitude 6.0 earthquake near Neiafu, Vava'u, Tonga, was reported only 14 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate to considerable depth of 237 km beneath the epicenter early morning on Sunday, June 5th, 2022, at 2:07 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.

Island was also hit with 6.9 magnitude quake two weeks ago
A magnitude 6.4 earthquake has struck the west of Australia's Macquarie Island.

The island, about 1,600km southeast of Tasmania, felt the earthquake late on Saturday night.

No damage has been reported so far.

The earthquake had a depth of 10km and is believed to have been felt shortly after 11pm.

A 6.9 magnitude earthquake also hit the island two weeks ago, briefly placing Australia on tsunami watch.

4 dead, 14 injured after earthquake hits China's Sichuan

At least four people are dead and 14 others injured after two earthquakes hit southwestern China on Wednesday, state media reported.
At least four people are dead and 14 others injured after two earthquakes hit southwestern China on Wednesday, state media reported.
Four people have been confirmed dead and 14 others are injured after an earthquake jolted the city of Ya'an in southwest China's Sichuan Province on Wednesday afternoon, according to the city's earthquake relief headquarters.

A 6.1-magnitude earthquake rattled Lushan County of Ya'an in Sichuan, at 5 p.m. Wednesday Beijing Time, according to the China Earthquake Networks Center (CENC).

The epicenter, with a depth of 17 km, was monitored at 30.4 degrees north latitude and 102.9 degrees east longitude, the CENC said.

The earthquake was followed by a 4.5-magnitude quake at 5:03 p.m. in Baoxing County, the city of Ya'an.

UK hit by over 20 earthquakes already in 2022: where and when they've hit

Britain is shook by earthquakes a lot more often than people realise

Shropshire residents were shocked by a 3.8 magnitude earthquake yesterday (May 30). But, they occur much more frequently in Britain than you'd expect.

The quake was the third to hit the UK in the last 24 hours, taking place at around 3.36pm and at a depth of 4.9 miles. According to the British Geological Survey (BGS), 3.8 magnitude earthquakes only happen in the UK around every two years.

However, unbeknownst to many of us, the tremors are not unusual in the UK: it's just that a lot of the time, we miss them. But over the years, the South East has been subject to some of the biggest in the country.

This week in volcano news - Hunga Tonga is erupting, Hualalai earthquake

erupts

In the last week, it was discovered that the Hunga Tonga Hunga Ha'apai volcano is still erupting. New information shows that the volcano produced a VEI 6 eruption, deepening its caldera by more than 700 meters or 2000 feet. Meanwhile in Hawaii, a moderate magnitude earthquake occurred on the flanks of the Hualalai volcano, leading some to suspect that it was volcanic in origin. And, in Papua New Guinea, magmatic uplift was detected at a volcano which has not erupted in more than 135 years. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.
