Russia: A magnitude-5.9 offshore earthquake occurs off the southeast coast of the Kamchatka Peninsula at around 00:21 Oct. 1

A magnitude-5.9 earthquake occurred off the southeast coast of the Kamchatka Peninsula at around 00:21 Oct. 1. The epicenter was about 91 km (56 miles) east of Petropavlovsk-Kamchatsky. The tremor occurred at a depth of about 33 km (21 miles), and moderate-to-light shaking was probably felt in southern coastal areas of the Kamchatka Peninsula close to the epicenter. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light-to-moderate aftershocks are likely over the coming days. The event has not prompted any tsunami advisories.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
