A long dormant volcano erupted on Russia’s Kamchatka Peninsula, just days after the magnitude 8.8 megakoki rocked the area on July 30th. Following the Kraichevskoy eruption within hours last week, it is the second volcano to blow the top in the region in the last five days.
For the first time in about 500 years, the approximately 6,000-foot-high (1,800 meters) Krasininikov volcano erupted overnight on Sunday (August 3). The eruption blew 3.7 miles (6 km) of ashes plume into the sky, but poses no threat to the populated areas.
A magnitude 7.0 earthquake also hit the area on Sunday. The National Oceanic and Atmospheric Administration (NOAA) tsunami warning system registered the latest earthquake at 6:37am local time for the Kuril Islands, a volcanic archipelago that stretches from the southern tip of the Kamchatka Peninsula to the northeastern tip of Japan.

After the earthquake, Russia issued a tsunami warning to the peninsula, but authorities later canceled the warning, Reuters reported.
This latest eruption and earthquake could be linked to the Megakoki that hit the peninsula on July 30th.

Last week, Russian scientists warned that strong aftershocks could occur in the peninsula region for weeks, Reuters reported.
It is unknown exactly when Krashen Gannikov volcano began erupting. Nikolai Solovyov, head of security services at the Russian federal state budget agency Kronotsky Nature Reserve, reported that he received a message regarding the start of local time at 6am on Sunday.
The Krachen Gannikov volcano has been dormant for hundreds of years. Olga Gilina, head of the Kamchatka Volcanic Eruption Response Team, told Russia’s RIA News Agency that it was the first historically confirmed eruption in 600 years, Reuters reported. At the Telegram Channel Institute of Volcanic Seismic Science, Girina also stated that within 40 years of 1463 the last lava exudation, or pouring of lava, occurred. However, the Smithsonian Association’s Global Volcanic Activities Program states that the last known eruption was after 1550 years.
Researchers are still able to learn much about last week’s Megakoki and more recent activities in the Kamchatka Peninsula. Major earthquakes (magnitudes above 6.0) can be linked to subsequent eruptions or volcanic anxiety. However, according to the US Geological Survey (USGS) website, in places where sufficient “spurt-outable” magma and magma are stored, this is the case, so the volcano must already be poised to erupt.
“If these conditions are present, large structural earthquakes could emerge from the magma (like a rocking soda bottle), which could increase pressure and possibly lead to an eruption,” a USGS representative wrote on its website.
