Fire and megathrust in one place

One of the busiest subduction zones on the planet - quakes and volcanoes together.

Kamchatka is where the Pacific Plate plunges under the Russian Far East, producing great earthquakes, Pacific-wide tsunamis and a dense cluster of active volcanoes. It is one of the most seismically and volcanically active regions on Earth.

What is happening at Kamchatka and the Kuril Arc

Along the Kamchatka and Kuril trenches the fast-moving Pacific Plate subducts steeply, generating frequent large earthquakes and feeding dozens of active volcanoes above.

Great megathrust quakes here have sent tsunamis across the Pacific. The same subduction that shakes the peninsula builds volcanoes like Klyuchevskoy, among the most active anywhere.

    A powerful Kamchatka megathrust earthquake triggered Pacific tsunami alerts.

What scientists watch

Russian and Pacific-wide networks monitor the trench for great quakes and issue ocean-wide tsunami warnings when they strike.

Staying ahead of it

Megathrust quakes here launch ocean-crossing tsunamis - the earliest warning protects coastlines thousands of kilometres away.

Kamchatka and the Kuril Arc: common questions

Why is Kamchatka so active?

The Pacific Plate subducts rapidly beneath it, producing frequent great earthquakes and feeding one of the densest clusters of active volcanoes on Earth.

Can a Kamchatka earthquake cause a tsunami far away?

Yes. Great megathrust quakes here have sent tsunamis clear across the Pacific, which is why they trigger ocean-wide warnings within minutes.
