koryaksky erupted for the first time in 1890.the eruption was big caused by lava emissions from fissures and phreatic explosions.they thought it was going to erupted again five years later but it show that there was no eruption going on.there was simply steam generated by strong fumarolic exploded in 1962 after the volcano lay dormant until 1956.the explosive in 1956 erupted more than the eraption with VEI and generated pyroclastic flows and lahars.

Koryaksky erupted for the first time in recorded history in 1890. The eruption was characterised by lava emissions from fissures that opened up on the volcano's southwestern flank, and by phreatic explosions. It was thought to have erupted again five years later, but it was later shown that no eruption had occurred; what was thought to be an eruption column was simply steam generated by strong fumarolicactivity.
Another brief, moderately explosive eruption occurred in 1926, after which the volcano lay dormant until 1956. The 1956 eruption was more explosive than the previous known eruptions, with VEI=3, and generated pyroclastic flows and lahars. The eruption continued until June 1957.
On December 29, 2008, Koryaksky erupted with a 20,000 foot plume of ash, the first major eruption in 3,500 years.[3]
In light of its proximity to Petropavlovsk-Kamchatsky, Koryaksky was designated a Decade Volcano in 1996 as part of the United Nations' International Decade for Natural Disaster Reduction, together with the nearby Avachinsky volcano.

Koryaksky lies on the Pacific Ring of Fire, at a point where the Pacific Plate is sliding underneath the Eurasian Plateat about 80 mm/year. A wedge of mantle material lies between the subducting Pacific Plate and the overlying Eurasian Plate is the source of dynamic volcanism over the whole Kamchatka Peninsula.
The volcano has probably been active for tens of thousands of years. Geological records indicate that there have been three major eruptions in the last 10,000 years, at 5500 BC, 1950 BC and 1550 BC. These three eruptions seem to have been mainly effusive, generating extensive lava flows.

An eruption occurred at Koryaksky Volcano, Kamchatka, Russia on 17th August. Ash emissions reached a height of 4000 m above sea level and extended 20 km from the volcano. Koryaksky volcano is located 28 km from Petropavlovsk-Kamchatsky, the administrative centre of Kamchatka peninsula. Elevated volcanic tremor began on Saturday 15th August 2009. Koryaksky resumed eruptions in 2008 after a 51 years of inactivity.
2003 Earthquakes
An increase in seismic activity occurred at Koryaksky Volcano in December 2003. A magnitude 3.6 earthquake occurred in the crater, followed over the next 2 hours by a series of 6-km deep tremors
1994 Earthquakes
Between 6th March and 8th April 1994 there was a significant increase in seismic activity at the volcano, with 43 earthquakes a depth of 5 km.
1956-57 Eruption
Weak eruptions occurred in 1956-57 at the volcano. A 400-500 m long fissure formed on NW slope of the volcano at 3000-3100 m elevation, which erupted gas and ash. Emissions reached a relative height of 350 m and erupted at a rate of 150 m/s. Some ashfall was reported 18 km from the volcano.
