Japan rocked by second quake in 48 hours, but no tsunami warning issued
An earthquake with a preliminary magnitude of 6.1 jolted northeastern and eastern Japan on Thursday morning, the Japan Meteorological Agency said. No tsunami warning was issued.
The quake, which occurred at 6:23 a.m., measured 4 on the Japanese seismic intensity scale of 7 in Fukushima and Ibaraki prefectures, the agency said.
The quake did not cause any fresh problems at the Fukushima facilities, public broadcaster NHK cited the plant’s operator Tokyo Electric Power as saying.
The early-morning jolt followed Tuesday’s powerful 6.9-magnitude earthquake which sparked panic and triggered a tsunami including a one-metre (three-foot) wave that crashed ashore at the Fukushima plant.
Japan sits at the junction of four tectonic plates and experiences a number of relatively violent quakes every year.
A massive undersea quake that hit in March 2011 sent a tsunami barrelling into Japan’s northeast coast, leaving more than 18,000 people dead or missing, and sending three reactors into meltdown at the Fukushima nuclear plant.
In April, two strong earthquakes hit southern Japan’s Kumamoto prefecture followed by more than 1,700 aftershocks, leaving at least 50 dead and causing widespread damage.
