TOKYO: A strong earthquake on Friday (Oct 5) jolted the same area of Japan's northernmost main island of Hokkaido that was hit by one of the country's most powerful tremors last month.

The quake, which struck at 8.58am (7.58am Singapore time), had a preliminary magnitude of 5.3, and measured a "weak 5" on Japan's quake intensity scale of 1 to 7, with 7 being the strongest, Japanese broadcaster NHK said.

There was no danger of a tsunami from the quake, it said.

According to local authorities, a woman in her 30s in Sapporo sustained slight injuries, but no other casualties or instances of damage were reported, NHK said.

Bullet train services were temporarily stopped, but has since resumed. The New Chitose Airport near Sapporo is operating normally, NHK reported, citing the transport ministry. 

In a news conference on Friday morning, the Japan Meteorological Agency said there may be a higher risk of landslides or buildings collapsing in areas hit by the tremors. It also advised caution against seismic activity or rainfall that may follow the earthquake during cleanup or restoration works. 

Heavy rain and strong winds due to Typhoon Kong-rey's approach over the weekend may also result in landslides.

The US Geological Survey said the quake, which it measured at 5.2 magnitude, was 42km deep and centred on Hokkaido's southern coast.

A magnitude-6.7 quake on Sep 6 paralysed Hokkaido, an island the size of Austria, killing dozens, triggering landslides and temporarily knocking power to all 5.3 million of its residents.
