On Wednesday, a 7.2 magnitude earthquake hit off Russia’s Kuril Island, said the authorities. The brief tsunami threat led the local residents to seek higher ground. The epicenter of the quake is located 210 kilometres (130 miles) southeast of Severo-Kurilsk, a town of around 2,500 people on the Kuril island of Paramushir, said the Russian emergencies ministry.
Officials reported no casualties or damage but said 400 residents of Severo-Kurilsk were taken to higher ground. The ministry further reported that a small tsunami wave of about 50 centimetres (1.6 feet) high had hit the shore.
The strength of the earthquake was estimated by the US Geological Survey claiming it to be a 7.5 magnitude. The quake struck at a depth of 37 miles, around 850 miles northeast of the Japanese city of Sapporo, USGS added.
The Pacific Tsunami Warning Center said “only very small tsunami waves were generated by this earthquake and there is no further threat”. According to the Japan Meteorological Agency, the quake was a stronger 7.8 magnitude and may cause a slight change of sea levels around Japanese coasts.
