The increase in the seismic activity of the Koryaksky volcano was registered in Kamchatka (Russia's Far East).
For the first time in many years a 3.6-strong earthquake was registered yesterday in the volcano crater, the Kamchatka experimental seismological laboratory disclosed to a RIA Novosti correspondent. Within the next 2 hours a series of 6-km deep tremors.
The active cyclone at the peninsula obstructs visual observations.
The last eruption of the Koryaksky volcano situated 30 km from Petropavlovsk-Kamchatsky was registered in 1956. Back then, a slit on the northwestern slope of the volcano opened and the volcano erupted gas and ashes. The eruption was weak and continued until March of 1957.
At present 3,456-meter-high volcano poses no danger to the population of the nearby settlements.
