Another Massive Earthquake Hits Japan; Tsunami Warning Sounded

Japan got hit by yet another earthquake early today morning at about 8:31 UTC. The magnitude of the quake is 7.4 on the Richter scale and a tsunami warning has been issued.

The USGS reported the magnitude of the quake as 7.4 on the Richter Scale band also reported an aftershock measuring a massive 6.2 following the quake. The depth of the epicenter is 33 km and the epicenter lies 333 km from Sendai.

Even Tokyo felt the tremors, but there has been no reports of any damage of death. The 1-m high tsunami warning is still on for the Miyagi prefecture, which was badly damaged in the 2011 tsunami. The devastated Fukushima nuclear power plant suffered no further damages. The quake wasn’t strong enough to create a pacific wide tsunami.

Japan lies near the fault of four massive plates – the Pacific plate, the North American plate, the Eurasian plate and the Phillipine Sea plate. This makes it particularly susceptible to the strike-slip earthquakes, in which the plates just slip against one another. Massive tectonic forces operating at these faults can cause huge earthquakes.
