A powerful 7.8-magnitude earthquake struck off the coast of Russia's far eastern Kamchatka peninsula early Friday, September 19, rocking buildings and prompting authorities to issue a tsunami alert. Videos posted on Russian social media showed furniture and light fixtures shaking in homes, while another showed a parked car rocking back and forth on a street.

The quake struck 128 kilometers (80 miles) east of the region's capital, Petropavlovsk-Kamchatsky, and at a shallow depth of 10 kilometers (six miles), the US Geological Survey (USGS) reported. The local branch of Russia's state geophysical service gave a lower estimated magnitude of 7.4. It reported at least five aftershocks.

The Pacific Tsunami Warning System briefly issued a tsunami threat but later lifted it.

"This morning is once again testing the resilience of Kamchatka residents," the governor of the region, Vladimir Solodov, said on Telegram. "There are currently no reports of damage. I ask everyone to remain calm," he added, initially warning of the tsunami threat.

The Kamchatka peninsula lies on a tectonic belt known as the Ring of Fire, which surrounds most of the Pacific Ocean, and is a hotspot for seismic activity.

Last Saturday, a 7.4-magnitude earthquake struck off the coast in the same region, the United States Geological Survey (USGS) said. And in July, an 8.8-magnitude mega-quake off the region's coast triggered a tsunami that swept part of a coastal village into the sea.
