7.0-magnitude quake hits in Japan, small tsunami reported
A Strong 7.0-magnitude earthquake struck off the southwestern coast of Japan early Saturday, the US Geological Survey (USGS) said, with Japanese authorities reporting several small tsunamis on at least two islands.
The USGS put the epicentrum of the shallow quake about 160 kilometres (100 miles) from the town of Makurazaki in southwest Japan, though no major damage was initially reported.
Tsunamis measuring one metre (30 cm) in height were observed on several islands, public broadcaster NHK reported, citing local authorities, who were urging people in low lying areas to move away to higher ground for safety.
Authorities said larger tsunamis were still possible and urged caution more than an hour after the earthquake.
The Pacific Tsunami Warning Center had earlier said that there was no tsunami threat from the quake, which struck at 5:51am
Japan’s islands are situated at the juncture of several tectonic plates and experience a number of relatively violent quakes every year.
But building codes are rigorous and regular disaster drills are held, helping to ensure that despite their frequency and magnitude, quakes usually pass without loss of life or significant damage to property in Japan.
A massive undersea quake that hit in March 2011 sent a tsunami barrelling into Japan’s northeast coast.
As well as killing thousands of people and destroying communities, the waves also overflow the cooling systems at the Fukushima nuclear plant, sending three reactors into meltdown.
The nuclear disaster, the world’s worst since Chernobyl, displaced tens of thousands of people and rendered tracts of land uninhabitable, possibly for decades.
