TOKYO- On Tuesday, a strong and shallow earthquake struck Japan`s northwest coast around Niigata prefecture, triggering a small tsunami, shaking buildings and cutting power to around 9,000 buildings.
According to the US Geological Survey (USGS), the 6.4 magnitude earthquake lasted for as long as 20 seconds and damage included a landslide that struck a road, according to public broadcaster NHK. There were no initial reports of fatalities or fires.
Authorities lifted a 0.2-1.0 metre tsunami warning for the region after waves several centimetres high struck parts of the Niigata coast. A tsunami of up to one metre could have caused some flooding and damage in low-lying coastal areas and river banks, though much of Japan`s coastline is guarded by sea walls.
"We will work closely with local authorities to provide any disaster measures including lifesaving and rescue operations and have instructed officials to provide information in a timely and accurate manner," Chief Cabinet Secretary Yoshihide Suga - the top government spokesman - told a media briefing.
