Bezymianny in Kamchatka ejected a 12,000-meter-tall ash cloud, Russia's air regulator said

Aircraft have been strongly advised to review their flight routes due to a powerful volcanic outburst in Russia's far-eastern peninsula of Kamchatka, according to a statement by the Federal Agency for Air Transport, Rosaviatsiya, published on Saturday.

Rosaviatsiya said that on Friday morning Bezymianny volcano, which is located in the eastern part of the peninsula and is considered to be one of the most active in the region, erupted with a 12,000-meter column of ash, which then started to drift off to the southeast.

Indonesia's Anak Krakatoa volcano erupts, belches huge ash tower

The offspring of Indonesia's infamous Krakatoa volcano erupted several times on Tuesday, sending a huge volcanic ash tower some 2,500 meters (8,200 feet) into the sky.

Mount Anak Krakatoa, which means Child of Krakatoa, erupted four times, officials said, with the biggest followed by another that sent a column of smoke and ash 1,500 meters above its crater.

"This is part of an eruption phase associated with the formation of a new body for the volcano," Oktory Prambada, an official at the Center of Volcanology and Geological Hazard Mitigation, told AFP.

In 2018, its crater partly collapsed when a major eruption sent huge chunks of the volcano sliding into the ocean, triggering a tsunami that killed more than 400 people and injured thousands.

There were no immediate reports of injuries or damage on Tuesday.

MMMMM
Indonesia's Mount Merapi, one of the world's most active volcanoes, erupted late Friday and continued to spew hot ash and other volcanic material on Saturday.

Footage of flaming lava pouring out of the crater and a tall column of hot cloud rising 1,300 metres into the air was taken by the government-run Merapi Volcano Observatory on Friday night.

The volcano continued to spew hot ash and hot lava was visible on Saturday.

"Residents should anticipate the disruption due to the volcanic ash from Mount Merapi eruption and please be on alert for the danger of volcanic mudflow, especially when it rains around Merapi," the country's volcanology agency said in a statement Saturday.

The effusive eruption of the volcano remains intense.

We are regularly given first-hand information from our local expedition leader and volcanologist, Andi, about the volcano's behavior. Glowing lava blocks continue to detach from the actively growing lava dome, located within the Crater 1, and roll over the western and eastern slopes, most of which reach the base of the dome area. Feel free to enjoy a noteworthy video from the ongoing activity here.

Some people have been evacuated to avoid being affected by large hot rock falls that may result in dangerous pyroclastic flows.

Indonesia's Mount Merapi, one of the world's most active volcanoes, erupted on Saturday (Mar 11), spewing out smoke and ash that blanketed villages near the crater.

There were no immediate reports of casualties, the country's disaster mitigation agency said.

Images broadcast on local outlet Kompas TV showed ash-covered houses and roads at a village near the volcano, located on Java Island, near Indonesia's cultural capital Yogyakarta.

The Merapi Volcano Observatory estimated the ash cloud reached 3,000m (9,600 feet) above the summit.

The Energy and Mineral Resources Ministry's Geology Agency on Wednesday increased the status of Mount Karangetang which is located at Siau Island, North Sulawesi. The status of the volcano was bumped up from Level II Alert to Level III as of February 8

The agency's acting head Muhammad Wafid in a statement on Wednesday explained that Level III Alert bans human activities within a 2.5-kilometer radius from the mountain's crater and 3.5 kilometers in its southern and southeastern region.

According to Wafid, the increased status effectively means local residents living alongside the riverbank coming from Mount Karangetang will have to stay alert for possible lava flow.

Footage filmed on Russian Sakhalin Region's Paramushir Island on Wednesday shows cloud of smoke and gas erupting from Ebeko volcano's Korbut crater.

The report on the official website of Russian Federal Service for Hydrometeorology and Environmental Monitoring warned about remaining danger for flights in the Ebeko volcano area from January 31 to February 1.

Volcano of Ebeko is a complex stratovolcano with several vertex craters located seven kilometres from Severo-Kurilsk on the Vernadsky Ridge.

The volcano has been regularly erupting ash since October 2016. The last one was recorded on 1st of September 2022. At that time, the height of ash column reached four kilometres.

Mexico's Popocatepetl volcano erupted twice on Tuesday, January 31, with authorities cautioning residents to stay alert for expected ash fall in surrounding municipalities.

Footage captured by a fixed camera in San Nicolas de los Ranchos, Mexico, shows the moment the eruption occurred at 12:29 am Tuesday morning, followed by a second eruption at 6:59 am.

The National Civil and Protection Service said the "moderate explosion" shot "incandescent fragments" almost 2 kilometers (1.25 miles) from the crater rim.

Earthquakes increase from 60 to 600 per week in just 5 years in Pahala, Hawaii

Shaded white areas show dense regions of earthquakes interpreted as the Pāhala sill complex. Dashed white box outlines a region of sparsely spaced volcano-tectonic earthquakes that lie between the Kīlauea summit and Pāhala.
Pāhala, a town located in the southeast part of the Island of Hawai'i, lies above the state's most seismically active area. In the last 5 years, the average weekly number of earthquakes has increased from about 60 to 600 earthquakes per week.

These frequent earthquakes occur deep beneath the Pāhala region at approximately 20 to 40 km (12 to 25 miles) depth. Larger events are regularly felt by residents living both within Pāhala and across the island.

In a 2015 study, scientists at USGS located and classified earthquakes in this region into two main groups.

A more continuous seismic tremor, a type of signal often used to trace the movement of magma within a volcanic system, was identified at approximately 40 km (25 miles) depth, both on- and off-shore of the Pāhala region. This activity was interpreted as the migration of magma from the deep Hawaiian hot spot to more shallow depths.

Surprise magma chamber growing under Mediterranean submarine volcano Kolumbo

Using a novel imaging technique for volcanoes that produces high-resolution pictures of seismic wave properties, a new study reveals a large, previously undetected body of mobile magma underneath Kolumbo, an active submarine volcano near Santorini, Greece. The presence of the magma chamber increases the chances of a future eruption, prompting the researchers to recommend real-time hazard monitoring stations near other active submarine volcanoes to improve estimations of when an eruption might be likely to occur.

Nearly four hundred years ago, in 1650 C.E., Kolumbo breached the sea surface and erupted, killing 70 people in Santorini. This eruption, not to be confused with the catastrophic Thera (Santorini) volcanic eruption that occurred around 1600 B.C.E., was triggered by growing magma reservoirs beneath the surface of Kolumbo. Now researchers say the molten rock in the chamber is reaching a similar volume.

Comment: Taken together with activity at other volcanoes, as well as with other related effects, such as undersea warming, there's strong evidence suggesting that volcanic activity across the planet is on the increase, however much of it goes unnoticed due to being submarine: And check out SOTT radio's:
