Russia quake sparks rare chain of Pacific Ring of Fire volcano eruptions

Pacific’s Ring of Fire erupted after a megaquake in Russia’s Kamchatka region on July 29, 2025, set off a huge volcanic chain reaction.

Volcanoes dormant for more than 600 years along the Pacific Ring of Fire erupted after the 8.8 magnitude quake followed by multiple aftershocks measuring up to magnitude 6.

Klyuchevskaya Sopka erupted for the first time in 600 years, while other volcanoes such as Shiveluch, Bezymianny, Karymsky and Avachinsky have revived after 300 years.

Scientists warned of an imminent eruption after detecting a thermal anomaly indicating rising heat at Mutnovsky.

A University of West Indies seismologist said, “I saw reports about multiple volcanoes erupting, which is a unique situation. Since the activity is dynamic, the numbers may change with time.”

In an interview with the Daily Mail, Ilias Papadopoulas said, “The region between Alaska and Russia is among the most seismically and volcanically active on Earth, the near simultaneous activity of so many volcanoes is rare.”

He also warned about the risk of more eruptions for human life, adding, “It would for sure make an exciting event.”

According to Michael Manga, a geoscientist at the University of California, Berkeley, “The volcanoes in the volcanic arcs, including Chile, the US Cascades, Japan, Indonesia and Kamachatka, are prone to erupt after earthquakes.”

He added that the tremors have raised eruption chances from 5 per cent to 12 per cent.

The Pacific’s Ring of Fire is a chain of seismologically and geologically active regions that encircle the Pacific Ocean, where many of the world's biggest earthquakes, volcanic eruptions and tsunamis occur.
