A massive 8.7-magnitude earthquake off Russia's Kamchatka triggers tsunami warnings across the Pacific.

An 8.7-magnitude earthquake off Russia's Kamchatka Peninsula triggered tsunami warnings and watches across the Pacific, including Hawaii, Alaska, California, Japan, and Guam. The first tsunami wave hit Japan's Hokkaido, with warnings of subsequent waves up to 3 meters high expected in Hawaii and other areas. Evacuations were ordered in affected regions, and authorities advised residents to move to higher ground. The quake, initially reported as 8.0, occurred at a depth of nearly 12 miles and was followed by several aftershocks.
