PETROPAVLOVSK-KAMCHATSKY. March 27. VOSTOK MEDIA – Koryaksky and Avachinsky volcanoes, located 25 km from Petropavlovsk-Kamchatsky, become more active. Specialists of the Geophysical Service detected the highest activity on March 25. The Kamchatka branch of the Geophysical Service of the Russian Academy of Sciences told Vostok Media, over 60 separate seismic shocks were registered by the devices in the volcanic area. Visual observation is complicated in view of weather conditions. The veil of clouds hides tops of the volcanoes. The last eruption of a volcano from the group of the Kamchatka “home” volcanoes – Avachinsky – occurred in 1991. As all three volcanoes are seen within a distance of 100 km, the eruption could be seen by dwellers of Petropavlovsk and closely located towns.
