Tokyo, 25 October
A 30-centimetre tsunami hit Japan today after a powerful and shallow undersea quake although there were no immediate signs of serious damage or injury, reports said.
People were being warned to stay away from the coast with the small wave rolling ashore in Ishinomaki around an hour after the 7.1 magnitude quake.
Workers at the crippled Fukushima nuclear plant were “ordered to evacuate from the waterfront”, Kyodo reported, also quoting the Tokyo Electric Power Company (TEPCO) as saying no new abnormalities had been found at the power station.
The quake struck at a depth of 10 kilometres at 2:10am local time (1710 GMT Friday), 327 kilometres southeast of Ishinomaki in Miyagi Prefecture, according to the US Geological Survey. The USGS intially said its magnitude was 7.5, and issued a green alert on its website, signalling a low probability of deaths or economic losses.
In the town of Ofunato, a 20-centimetre tsunami was logged just after 3 am. The waves were expected to hit several places along the northeast coast that was devastated by the huge tsunami of 2011.
