Russia's Klyuchevskoy volcano erupts sending ash nearly 10,000 feet into the air

The effusive-explosive eruption of the volcano continues at moderately high levels.

A larger and stronger explosion than the average and usual size of explosions at the volcano occurred yesterday. This event is characterized as vulcanian-type explosion.

Large amount of ash with area of 65x70 km rose 9,842 ft (3,000 m) above the summit crater and extended about 50 km to the south-southeast of the volcano.

The lava flow on the southeast flank along the Apakhonchich chute remains active, currently about 2,000 m long.


Italy's Stromboli volcano erupts in "high-intensity" explosion spewing lava and ash

Italy's Stromboli volcano erupted once again on November 16, spewing ash, lava, and debris in a "high-intensity" blast that was captured on webcam and on surveillance cameras.

Described as "high intensity," the Italian National Institute of Geophysics and Volcanology reported the explosion on top of the volcano that lasted for four minutes after weeks of relatively low-activity.

The Stromboli volcano is one of the most active on Earth.

Eruption of Stromboli volcano this morning
Another stronger-than-usual explosion occurred at the volcano minutes ago at 10:17 local time our correspondents on the island informed us.
From the village, a spectacular ash plume rising several 100 m above the summit could be seen. Soon after the eruption, moderately strong ash rain of small lapilli set in, covering all surfaces.

The color of most particles, up to a few mm in size, was mostly brown to reddish brown, described as "earthy". This could mean that most of the ejected material might be from older lava rocks in the summit craters or inside the vent, from collapsed parts of the craters or conduits. However, a small amount of lighter pumice was also present in the ash, probably representing a batch of fresh magma that had driven the explosion.

Last Tuesday (10 Nov), Stromboli also produced a significant above-average eruption. Such events are nothing unusual on the volcano and occur from time to time, but rarely more frequently than every few months or so. Whether this recent increase is a coincidence or hinting at a more pronounced change in activity level or type is currently unknown.

Karymsky volcano erupts emitting ashes 6 km high in Russia's far east

The Karymsky volcano in Kamchatka, a peninsula in far eastern Russia, erupted Friday, emitting ashes 6 km high, the Kamchatka Volcanic Eruption Response Team reported.

"A moderate eruptive activity of the volcano continues," the response team said in a statement. "The plume extended for 24 km to the northeast of the volcano."

The team designated an orange code to the volcanic activity, warning that it could affect low-flying aircraft.

There has been no evidence of ash reaching nearby settlements, the RIA Novosti news agency reported, citing the regional headquarters of the Russian Emergencies Ministry.


Mt. Sinabung in Indonesia erupts again, spews 2,000-meter-high volcanic ash clouds

Photo taken on Oct. 29, 2020 shows Mount Sinabung spewing volcanic materials at Tiga Pancur village in Karo, North Sumatra, Indonesia.
Mount Sinabung in Karo, North Sumatra, erupted again on Thursday morning, this time shooting hot volcanic ash 2,000 meters into the air while spewing a 1,500-m-high ash column that affected a number of areas in the regency.

The eruption occurred at around 7:52 a.m. local time and followed an eruption on Sunday in which the volcano ejected hot ash clouds but not an ash column.

"This is the first time this month that the volcano erupted hot clouds together with volcanic ash," Mt. Sinabung observation team member Armen Saputra told The Jakarta Post on Wednesday.


Ebeko Volcano on Kuril Islands, Russia spews ash 3 miles Into sky

The Ebeko volcano on the Paramushir island, located in the Russian Kuril Islands archipelago, emitted a column of ash about 5 kilometers (3 miles) high into the sky, the Kamchatka Volcanic Eruption Response Team (KVERT) said on Monday.

"The height of the volcanic cloud is 4,000 - 5,000 meters. A moderate eruptive activity of the volcano continues. Ash explosions at an altitude of 6-7 kilometers above sea level can occur at any moment. Current activities can affect low-flying aircraft," KVERT said, adding that the aviation alert-level was set to orange.

Ebeko woke up in 2016 and has repeatedly spewed ash since then.


Mt. Sinabung in Indonesia spews hot ash, surroundings evacuated

The Volcanology and Geological Hazard Mitigation Center (PVMBG) has warned the public to avoid Mount Sinabung in Karo regency, North Sumatra, and has evacuated nearby settlements as the volcano spews hot ash.

According to the PVMBG the volcano emitted a burst of hot ash at 12:51 p.m. on Sunday. The ash drifted some 1,500 meters southeast of the crater. It unleashed more ash, which drifted some 2,500 meters southeast, at 8:58 p.m. on the same day.

"We need to be cautious because the lava dome in Mt. Sinabung is growing every day. The condition can lead to a huge flow of hot ash," Mt. Sinabung observation team member Muhammad Nurul Asrori told The Jakarta Post on Monday.


'Lost' tectonic plate discovered under the Pacific

A 3D block diagram across North America showing a mantle tomography image reveals the Slab Unfolding method used to flatten the Farallon tectonic plate. By doing this, Fuston and Wu were able to locate the lost Resurrection plate.
Scientists have reconstructed a long-lost tectonic plate that may have given rise to an arc of volcanoes in the Pacific Ocean 60 million years ago.

The plate, dubbed Resurrection, has long been controversial among geophysicists, as some believe it never existed. But the new reconstruction puts the edge of the rocky plate along a line of known ancient volcanoes, suggesting that it was once part of the crust (Earth's top layer) in what is today northern Canada.

"Volcanoes form at plate boundaries, and the more plates you have, the more volcanoes you have," Jonny Wu, a geologist at the University of Houston, said in a statement. "Volcanoes also affect climate change. So, when you are trying to model the Earth and understand how climate has changed ... you really want to know how many volcanoes there have been on Earth."

Wu and his co-author, University of Houston geology doctoral candidate Spencer Fuston, used a computer model of Earth's crust to "unfold" the movement of tectonic plates since the early Cenozoic, the geological era that began 66 million years ago. Geophysicists already knew that there were two plates in the Pacific at that time, the Kula plate and the Farallon plate.

Karymsky volcanic eruption on October 21, 2020.

Karymsky (Russian: Карымская сопка, Karymskaya sopka) is an active stratovolcano on the Kamchatka Peninsula, Russia. It is currently the most active volcano on the Kamchatka Peninsula, as well as the most active volcano of Kamchatka's eastern volcanic zone.

It is named after the Karyms, an ethnic group in Russia.
