A magnitude-7.8 earthquake has struck the Petropavlovsk-Kamchatsky region in eastern Russia, prompting tsunami warnings for parts of the United States. The earthquake occurred 128 kilometers east of the Kamchatka Peninsula, which is located northeast of Japan. It struck at a depth of 10 kilometers, according to the US Geological Survey.

In response to the quake, the US National Oceanic and Atmospheric Administration (NOAA) issued several tsunami warnings. The agency indicated that tsunami waves could potentially affect coastlines within 1,000 kilometers of the earthquake's epicenter. NOAA warned that waves could reach up to three meters above normal tide levels along some Russian coastlines.

The tsunami alerts also included potential threats for the Aleutian Islands and the Amchitka Pass in Alaska, which are situated across the northern Pacific Ocean. Meanwhile, officials in Hawaii are still assessing the tsunami risk for the islands and other coastal areas in the United States.

NOAA confirmed that there is no threat of hazardous waves for American Samoa, Guam, Rota, or Saipan. These alerts follow a previous incident in July when the Russian peninsula experienced a magnitude-8.8 earthquake, which also led to tsunami warnings and evacuations as far away as Japan and Hawaii.
