Three Powerful Earthquakes Strike Off Russia's Far East, Tsunami Alert Issued
The region was struck by 5.0-magnitude and 6.7-magnitude earthquakes, but they did not trigger a tsunami alert till another tremor of 7.4-magnitude.
Three powerful earthquakes of varying magnitudes struck off the coast of Russia's eastern region of Kamchatka on Sunday, triggering a tsunami alert by the US Geological Survey.
The region was struck by 7.0-magnitude and 6.7-magnitude earthquakes, but they did not trigger a tsunami alert. However, a 7.4 magnitude earthquake at 0849 GMT prompted the USGS to warn that 'hazardous tsunami waves are possible" within 300 kilometres (186 miles) of the epicentre in the Pacific.
There were no immediate reports of casualties. The initial earthquakes were followed by several aftershocks, including another 6.7-magnitude quake, said USGS. The epicentre was around 140 kilometres east of Petropavlovsk-Kamchatsky, capital of the Kamchatka region.
Russia's emergency situations ministry wrote on Telegram that it expected waves of up to 60 cm in the Commander Islands in the southwestern part of the Bering Sea, and waves of 15 to 40 cm in the Kamchatka peninsula.
Meanwhile, the German Research Centre for Geosciences (GFZ) indicated twin earthquakes of over 6.5 magnitude struck near the coast of Kamchatka on Sunday. It measured the quakes at 6.6 and 6.7 and the depth of both at 10 kilometres (6 miles).
The Kamchatka peninsula is the meeting point of the Pacific and North American tectonic plates, making it a seismic hot zone. Since 1900, seven major earthquakes of magnitude 8.3 or higher have struck the area.
On November 4, 1952, a magnitude 9.0 quake in Kamchatka caused damage but no reported deaths despite setting off 9.1-metre (30-foot) waves in Hawaii. The US state of Alaska sits across the Bering Sea from the city, but no American territory appeared to be in the alert zone in the latest tremors in the region.

'Delhi's Cleanest July In A Decade': Capital Breathes Easy With AQI In Rare 'Satisfactory' Phase
Last Updated: On Saturday, Delhi recorded an Air Quality Index (AQI) reading of 91 at 9 am, placing it within the 'satisfactory' range. The reading on July 23 had dropped to 67 Delhi, frequently plagued by intense air pollution, experienced a notable and much-needed improvement in air quality this July, with the AQI briefly reaching the 'satisfactory" category. On Saturday, Delhi recorded an Air Quality Index (AQI) reading of 91 at 9 am, placing it within the 'satisfactory" range. Even more remarkable was the reading on July 23, when the AQI dropped to 67, also classified as 'satisfactory" by the Central Pollution Control Board (CPCB). According to CPCB standards, an AQI between 0 and 50 is considered 'good'", while 51 to 100 is 'satisfactory", indicating minimal breathing discomfort for sensitive individuals. This improvement starkly contrasts with Delhi's usual high pollution levels, especially during winter when the AQI often reaches 'severe" or 'very poor" categories. The ongoing monsoon season plays a crucial role in this change. Rainfall helps wash away particulate matter and pollutants, while increased wind speeds disperse residual pollutants, contributing to cleaner air. Historically, July has generally seen better air quality in Delhi compared to the post-monsoon and winter periods. Recent data suggests this July might be one of the cleanest in a decade, with an average AQI significantly lower than in previous years. Alongside the monsoon, consistent efforts by various civic agencies in pollution control, including enhanced street sweeping and landfill management, have helped maintain these improved levels. The brief period of 'satisfactory" air quality offers a glimpse of what cleaner air feels like in a city accustomed to smog and haze. view comments First Published: July 26, 2025, 17:15 IST Disclaimer: Comments reflect users' views, not News18's.
