Chilling warning after biggest earthquake in decades

Experts have warned that the 8.8 magnitude quake that hit off Russia, the largest earthquake in more than a decade, could set off a chain of volcanic eruptions across the Pacific Ocean ‘Ring of Fire’ putting millions of lives at risk on all sides of the ocean.

The Klyuchevskoy volcano in eastern Russia began erupting shortly after the earthquake, according to the the Geophysical Center of the Russian Academy of Sciences.

Cameras observing the volcano captured “explosions” and a “powerful glow above the volcano”, with “a descent of hot lava ... observed on the western slope”, the academy wrote on messaging app Telegram.

A representative for the US Geological Survey (USGS) told Live Science the volcano had been “showing signs of unrest” in the weeks leading up to the earthquake.

“While yesterday’s large earthquake did not cause the eruption to begin, it did likely increase in the vigour of the eruption including some ash emission,” the USGS representative said.

Klyuchevskoy, which rises 4754 meters above sea level on Russia’s Kamchatka Peninsula, sits on the Pacific Ring of Fire.

The Ring of Fire is an enormous belt of active and dormant volcanoes that surrounds most of the Pacific Ocean. It runs from southern Chile, up the west coast of the Americas, through the islands off Alaska and down Japan to the Philippines. Some geologists also include an Indonesian chain of volcanoes in the ring.

Experts have now warned that the earthquake could trigger volcanic eruptions.

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

He said volcanoes in the westernmost part of the Ring of Fire, covering Russia, Japan, the Philippines and Indonesia, were at increased risk.

Tsunami waves have hit the US mainland after the world’s biggest earthquake in 14 years sparked warnings for millions in the northern hemisphere.

However, the US’ Homeland Security Secretary Kristi Noem has said the threat to America has now “passed completely” by Wednesday afternoon, US time.

Waves did hit the US however. One more than 1 metre in height hit Crescent City in northern California on Wednesday morning, local time.

In Japan, wave heights reached more than 1.2 metres in the Kuji Port and Hamanaka areas. Tokyo said its nuclear power plants, including Fukushima on the coast which was the victim of a previous tsunami, were safe.

The worst-hit nation has been Russia with waves in some places of more than three metres and possibly up to five.

Images from the Pacific town of Severo-Kurilsk show damage caused by the waves including a fish processing plant that was washed away. Another video showed buildings in the town submerged in seawater.
