An earthquake of magnitude 6.8 occurred on August 10 in the southern Okhotsk Sea, near the coast of Hokkaido, Japan.
According to the Japan Meteorological Agency (JMA), the earthquake occurred at around 12:29 local time (10:29 Vietnam time). There is currently no tsunami warning following the earthquake.
Japan is scrambling to prepare for a possible mega-earthquake in the next week or so after the JMA issued a warning after a 7.1-magnitude earthquake off the coast of Miyazaki Prefecture, on the western edge of the Nankai Trench, shook the southwestern part of the country.
Experts warn that if a super earthquake occurs, strong tremors accompanied by high tsunamis could wreak widespread destruction, from the Kanto region in the west including Tokyo to the Kyushu and Okinawa regions in the south.
