Shiveluch, the northernmost active volcano on the Kamchatka Peninsula, has been erupting more or less continuously for as long as anyone has been watching. It produces roughly 0.015 cubic kilometers of magma per year, building and destroying lava domes at its summit in a cycle that generates pyroclastic flows, ash plumes, and aviation warnings with a regularity that would be terrifying if it were not so relentless. Along with Karymsky, it is one of the two most active volcanoes in Kamchatka -- and one of the most active on Earth.

In the geological record since then, at least 60 large eruptions have been identified during the Holocene alone. The volcano produces a remarkably diverse chemical menu: basalt, ma...

Shiveluch: April 2023: Ash Reaches the Stratosphere

Sat, 28 Mar 2026 00:00:00 GMT

Photo credit NASA, Public domain. Volcanologists had been on alert since mid-2022, watching Shiveluch's lava dome grow increasingly unstable. Activity intensified through late March 2023 -- continued extrusion, fumarole venting, rising ash emissions. Then, at 12:54 AM local time on April 11, the volcano erupted w...

Shiveluch: The Volcano That Grounds Airplanes

The volcano sits beneath some of the busiest air routes connecting Asia and North America, and volcanic ash -- invisible to radar, abrasive to turbine blades, capable of stalling jet engines -- makes every eruption a concern ...

Shiveluch: Living With a Restless Neighbor

It is the mountain on the horizon that periodically coats their roofs, their gardens, and their cars in fine gray powder. The town is small enough to evacuate rapidly -- a...
