Krasheninnikov Volcano Erupts in Russia After 600 Years – 3rd August 2025
It is located in Kronotsky Nature Reserve to the south of Lake Kronotskoye, and is named after explorer Stepan Krasheninnikov.
The tephra from the caldera’s forming eruption lies on top of material from an eruption 39,000 years ago. It is believed that the two layers are related. The southern of the two cones was constructed over a 4,500 year period beginning 11,000 years ago. The northern cone formed in the same amount of time, but started forming after the southern cone was complete.
A sample of Krasheninnikov’s eruptive product proved to be dacite.
On August 3, 2025, Krasheninnikov’s first eruption since the 16th century, and its first to be directly observed, began just 4 days after the 2025 Kamchatka Peninsula earthquake.

Shishaldin volcano, which has been erupting for days, sent an ash cloud 40,000 feet into the air above Unimak Island early Friday morning.
The volcano, located in the eastern Aleutian Islands, started showing signs of unrest Tuesday.
At around midnight on Friday, a large explosion sent up a plume of ash, followed by another explosion at around 8 a.m.
Nick Schwartz is a lead forecaster for the National Weather Service. He said flights were not majorly affected by these recent eruptions because the wind pushed the ash southward into the Pacific Ocean. But he said the situation remains dynamic because Shishaldin eruptions can change quickly.
“This morning it went from basically nothing to a plume height of over 35,000 feet in a matter of 10 minutes,” Schwartz said.
Hannah Dietterich is a research geophysicist with the U.S. Geological Survey. She called Shishaldin an “open system,” meaning there is an easy pathway for the magma to travel.
“So those eruptions can happen with less warning time than other systems,” she said.
Dietterich said volcanic eruptions can last for many months, so be prepared — whether it be to protect yourself from ash fall, or to be flexible with travel plans due to possible flight cancellations.
“It’s a pretty active place,” Dietterich said. “It’s part of the Alaska experience.”

Residents flee in panic as Indonesia’s Semeru volcano erupts

Indonesia’s Semeru volcano on Java island has erupted, spewing thick columns of ash high into the sky and triggering panic among people living nearby.
There were no immediate reports of casualties from Saturday’s eruption.
Videos shared by the country’s disaster mitigation agency (BNPB) showed residents running as towering smoke and ash blanketed some nearby villages in Lumajang district in East Java province.
The sudden eruption was accompanied by a thunderstorm and rain, which pushed lava and smouldering debris and formed thick mud that destroyed at least one bridge connecting two main villages of Pronojiwo and Candipuro, as well as hampering the evacuation, Lumajang district head Thoriqul Haq told TV One.
“Thick columns of ash have turned several villages to darkness,” Haq said, adding that several hundred people were moved to temporary shelters or left for other safe areas.
Television reports showed people running in panic under a huge ash cloud, their faces wet from rain mixed with volcanic dust.
The 3,676-metre (12,060-foot) Semeru, the highest on the country’s most densely populated island, had last erupted in January, with no casualties.
Indonesia, an archipelago of more than 270 million people, is prone to earthquakes and volcanic activity because it sits along the Pacific “Ring of Fire,” a horseshoe-shaped series of fault lines. Indonesia has about 128 active volcanoes.

Large Explosion at Aso Volcano, Kyushu Island, Japan

Explosion from Aso’s Nakadake crater this morning (image: screenshot of RKK video)
A strong explosion occurred this morning, at around 11:43 local time, from the volcano.
During a phase of intense steam emissions, suddenly an explosion occurs that sends a large column of ash to several kilometers height as well as a dense, ground-hugging circular base surge that almost reaches the visitors’center. On the following embedded video, large ballistic projectiles can be seen ejected from the center of the explosion and landing in several hundred meter distance as well.
From the appearance of the eruption, it looks most likely as a phreatic type explosion, or steam-driven, as a larger pocket of overheated water under the crater suddenly flashed to steam and decompressed in the process, generating lots of block and ash fragments as well as dense and heavy turbulent mixtures that are seen rising and spreading from the center.
