A powerful earthquake measuring 7.8 on the Richter scale struck off Russia’s Kamchatka Peninsula, though no immediate casualties or damage were reported. The U.S. Geological Survey said the quake’s epicenter was about 128 kilometers east of Petropavlovsk-Kamchatsky at a shallow depth of 10 kilometers. While a tsunami warning was initially issued, it was later withdrawn. Authorities had warned of waves up to 3 meters along parts of Russia’s coast, but no destructive tsunami was recorded, and no alerts were issued for U.S. or Canadian territories.
