The United States Geological Survey (USGS) recorded a magnitude 6.8 quake at 07:37 local time (UTC+2), about 118 kilometers east of Severo-Kurilsk, at an estimated depth of 35 kilometers.
Germany’s Research Center for Geosciences (GFZ) initially measured the quake at magnitude 6.35 and a depth of 10 kilometers (6.2 miles), later revising the magnitude to 6.7.
Severo-Kurilsk lies on a Pacific archipelago that is part of Russia’s Sakhalin Oblast.
Russia’s Ministry of Emergency Situations, cited by Reuters, warned of a potential tsunami and advised that waves could affect the Kamchatka Peninsula in Russia’s Far East.
No tsunami threat to Hawaii
The Pacific Tsunami Warning Center, which recorded the quake at magnitude 7.0, confirmed that there was no tsunami threat to the island of Hawaii.
This is the second major earthquake reported in the region in less than a week. On July 30, an 8.8-magnitude quake struck the area, followed by a series of strong aftershocks.
The seismic activity coincided with the eruption of the Krasheninnikov volcano on the Kamchatka Peninsula—part of the Kamchatka volcanic arc in eastern Russia—its first eruption in approximately 600 years, according to CNN, citing Russia’s RIA state news agency and geoscientists.
Russia’s state news agency also quoted Olga Girina, head of the Kamchatka Volcanic Eruption Response Team, as saying the eruption may be linked to Wednesday’s powerful earthquake, which triggered tsunami alerts as far away as French Polynesia and Chile.
