Vladivostok: A series of powerful earthquakes struck off the coast of Russia's Kamchatka Peninsula on Sunday, with the strongest reaching a magnitude of 7.6, the Kamchatka branch of the Unified Geophysical Service of the Russian Academy of Sciences announced on its Telegram channel. 

Emergency authorities said specialists will soon begin inspecting buildings in the affected areas. So far, there have been no immediate reports of casualties or major structural damage.

The quake was registered 115 km from Petropavlovsk-Kamchatsky, the capital city of Kamchatka Territory. Seismologists said data is still being processed and may be updated.
