Read more here:A volcano previously classified as "extinct" in Russia's far east has woken up, and experts are now warning it could produce an eruption similar to the one that wiped out Pompeii and Herculaneum almost 2,000 years ago.
The Bolshaya Udina volcano is a stratovolcano located at the center of the Klyuchevskaya volcano group on Russia's Kamchatka Peninsula. It stands at around 10,000 feet in height and, until 2017 it was considered extinct, meaning it has not erupted in a long time and is unlikely to ever erupt again.

Sorry, but no access to these new seismic stations, or any of the volcanoes on the Kamchatka Peninsula.
