6.3-Magnitude Quake Hits Japan's East Coast

Tsunami Alerts Follow 6.3-Magnitude Quake Near Japan

EMSC reported that the earthquake occurred at a depth of 32 km (19.88 miles). No immediate reports of damage or injuries were received. The epicenter, located 40 kilometers (25 miles) deep, was felt in Tokyo as well.

TEPCO, the operator of the Fukushima nuclear power plant, reported that "no abnormalities" had been detected at the stricken plant or other facilities in the region.

Japan, known as one of the world's most tectonically active countries, maintains stringent building standards to ensure structures can withstand even the most powerful earthquakes.

The archipelago, with a population of approximately 125 million people, experiences around 1,500 seismic jolts annually, the majority of which are mild.

The United States Geological Survey reported Thursday's quake magnitude as 6.1, with a depth of 40.1 kilometers.

The earthquake comes just a day after Taiwan was struck by a powerful quake, resulting in at least nine fatalities and over 1,000 injuries.

The magnitude-7.4 quake that occurred on Wednesday damaged numerous buildings in Taiwan and triggered tsunami warnings reaching as far as Japan and the Philippines.

Japan's largest recorded earthquake was a massive magnitude-9.0 undersea tremor in March 2011 off the northeast coast, which generated a devastating tsunami that resulted in approximately 18,500 fatalities or individuals reported missing.

The 2011 catastrophe also resulted in three reactors experiencing meltdowns at the Fukushima nuclear plant, leading to Japan's worst post-war disaster and the most significant nuclear accident since Chernobyl.

The total cost was estimated at 16.9 trillion yen ($112 billion), excluding the hazardous decommissioning of the Fukushima facility, a process expected to span decades.
