Earthquakes were continuous in Japan and the Philippines

On November 7-8, two intense and moderate earthquakes occurred, which in turn shook Japan's Okinawa island and Mindanao in the Philippines.

Japan and the Philippines are two countries in the Pacific that often experience earthquakes

Today (November 8), an earthquake measuring 6.8 on the Richter scale shook the waters off Okinawa Island, Japan, but no tsunami occurred.

According to the US Geological Survey (USGS), the earthquake occurred at 11:59 am (2:59 GMT) in the East China Sea, 218km from western Okinawa Prefecture. The depth of the earthquake is 222km.

There are currently no reports of casualties or casualties caused by this earthquake.

Yesterday (November 7), a magnitude 5 earthquake struck the small city of Valencia on Mindanao Island, injuring at least 10 people, damaging 23 houses, a computer store and 1 supermarket of vegetables in a population of 150,000 people.

According to the AFP news agency , casualties caused by heavy objects and houses collapsed when the earthquake struck at 5:43 pm (9:43 GMT), but no one was seriously injured.

The US Geological Survey (USGS) measures the magnitude of earthquakes at 5.2 Richter while Philippine seismologists provide a 5.2-Richter scale.

Winchell Sevilla, seismologist at the Manila-based Filipino Seismic and Volcanic Institute, said the cause of the earthquake was due to the displacement of the fault zone at the site about 1km below the earth's surface.

According to Sevilla, some other areas on the southern Mindanao Islands also felt the earthquake, although no reports of damage have been made.

The Philippines is located on the Pacific 'ring of fire' with many active volcanoes and trenches that often erupt and earthquake activities.

Meanwhile, Japan, which is located at the intersection of 4 tectonic plates, sees about 20% of the world's strongest earthquakes each year.

The tsunami after the March 11 earthquake has left about 22,000 people dead or missing and triggered a crisis at the Fukushima Daiichi nuclear power plant in the north of the country.
