An earthquake centred more than 120 km below the surface, by every agency’s depth estimate, shook Russia’s Kamchatka Peninsula on Friday afternoon local time, and early official reports point to tremors, some rattled households and no tsunami. The USGS event page lists a magnitude 6.9 quake at 03:35:31 UTC, 76 km NE of Ozernovskiy, at a depth of 135 km; Xinhua gives the local time as 15:35. The U.S. National Tsunami Warning Center tied its no-tsunami call to that depth: “Based on the depth of the earthquake, a tsunami is not expected.” For the U.S. side of the Pacific, the center wrote, “There is no tsunami danger for the U.S. West Coast, British Columbia, or Alaska.”
The size of the quake depends on which agency a reader checks. Reuters, in a short alert, said the European-Mediterranean Seismological Centre (EMSC) put it at magnitude 7 and 140 km deep. The EMSC catalogue entry this desk queried, last updated at 06:50 UTC, now lists Mw 6.9 at 133.9 km. The National Tsunami Warning Center’s preliminary bulletin gave 7.0 at 92 miles, about 95 miles SW of Petropavlovsk, Kamchatka, and PHIVOLCS gave 7.0 at 148 km. Business Standard, running an ANI feed, says India’s National Centre for Seismology recorded 7.0 at 152 km. Russian figures run lower: KamchatkaMedia says the Kamchatka branch of the Unified Geophysical Service of the Russian Academy of Sciences measured magnitude 6.5 at 127.8 km, 161 km from Petropavlovsk-Kamchatsky. Xinhua credits the same academy service with the 161 km distance and 127.8 km depth but gives magnitude 6.9. RIA Novosti runs 6.9 in its headline and 6.5 in its text. This desk shows every figure and does not average them. The tsunami center’s own bulletin warns that its parameters rest on “a rapid preliminary assessment of the earthquake and changes may occur.”
On the ground, Russia’s emergency ministry in Kamchatka said tremors could reach five points of felt intensity in Vilyuchinsk and Yelizovsky district and four points in parts of Petropavlovsk-Kamchatsky, Ust-Kamchatsky and Aleutsky, according to KamchatkaMedia and RIA Novosti, which both quote the ministry’s channel on the Max platform. The ministry said municipal duty-dispatch services received no calls from residents. RIA, citing the academy’s Kamchatka branch, places the epicentre on land in Yelizovsky district, 138 km SE of the village of Ust-Bolsheretsk, at 128 km depth. Xinhua reports that “No injuries or infrastructure damage were reported, and no tsunami warning was issued.”
Residents still felt it. A TASS correspondent in Kamchatka reported that some people in Petropavlovsk-Kamchatsky left their apartments as chandeliers swayed, doors banged and dishes rattled, and residents said the shaking went on without pause for about a minute, according to a news-kamchatka.ru item sourced to the TASS / Vostok channel. The USGS lists a green alert in its PAGER loss-estimate product and a peak modelled shaking intensity of about 5.6 on its ShakeMap. Business Standard (ANI), citing the EMSC, says the EMSC placed the epicentre about 146 km SSW of Petropavlovsk-Kamchatsky, a city of around 187,000 people.
The region has a recent history of much larger shocks. The USGS catalogues the “2025 Kamchatka Peninsula, Russia Earthquake” at magnitude 8.8 on July 29, 2025 (UTC). This desk found no agency statement linking Friday’s quake to that one.
Reading note: this desk wrote from agency pages and outlet copies, not field reporting. It read the USGS event data, the EMSC catalogue entry, the National Tsunami Warning Center bulletin and the PHIVOLCS advisory as primaries. It did not read the Russian emergency ministry’s Max post or the Unified Geophysical Service’s own bulletin directly; those lines rest on KamchatkaMedia, RIA Novosti and Xinhua. Magnitudes, depths and damage reports may still change.
