A magnitude 8.8 earthquake hits Russia, causing tsunamis over the Pacific Ocean.

On 30 July 2025, at 11:24:52 PETT, a M_w 8.8 megathrust earthquake struck off the eastern coast of the Kamchatka Peninsula in the Russian Far East, 119 km (74 mi) east-southeast of the coastal city of Petropavlovsk-Kamchatsky. It was the most powerful earthquake recorded worldwide since the 2011 Tōhoku earthquake, and is tied with the 1906 Ecuador–Colombia and 2010 Chile earthquakes as the sixth-strongest earthquake ever recorded by seismometers. However, it caused minimal damage compared to other earthquakes of similar magnitude. The earthquake caused moderate damage and multiple injuries in Kamchatka Krai and Sakhalin Oblast. The subsequent Pacific-wide tsunami was weaker than expected, with waves approximately 1 m (3 ft) or less in most places. However, a locally high run-up of 19 m (62 ft) as a result of a wave splash was recorded on Shumshu. One indirect fatality and 21 injuries were attributed to tsunami-related evacuations in Japan.

July 30 is the 211th day of the year in the Gregorian calendar; 154 days remain until the end of the year.
