0The Koryaksky volcano raising 3,456 m above sea level on the Russian Kamchatka Peninsula, 30 km from the region’s main city Petropavlovsk-Kamchatsky, is showing signs of higher seismic activity. Thirteen 3-magnitude tremors have been registered in the past 24 hours. After staying dormant for 52 years, Koryaksky woke up in December 2008, sending plumes of ash and steam into the air. So far, it poses no threat to local residents, but trails of ash and smoke endanger air flights. Caught amid turbines, particles of magma can cause engine failure. The peak of Koryaksky’s volcanic activity occurred 7,000 and 3,500 years ago.
