The 6.3 magnitude tremor struck Russia's Far East at a depth of 15.4 kilometers with its epicenter located 183 kilometers from Petropavlovsk-Kamchatsky, according to the Unified Geophysical Service. State news agency RIA Novosti reported that the quake was felt in the port city, which serves as the administrative center of the Kamchatka region.

The earthquake followed a 5.6 magnitude tremor recorded off the coast at 06:51 UTC earlier the same day, the UGS noted. The earlier quake was reportedly felt more intensely in populated areas despite its lower magnitude, though no casualties or damage were immediately reported.
