Small tsunami hits Japan after powerful 8.2 earthquake off coast of Chile
Bigger waves may strike the coast later, authorities warn

Small tsunami waves hit northern Japan early on Thursday following a powerful 8.2-magnitude earthquake thousands of kilometres away across the Pacific Ocean off the coast of Chile.
The Japan Meteorological Agency said waves of 20 centimetres were monitored in Kuji, Iwate prefecture, at 6:52am.
Minor tsunamis were also recorded in several other areas of northern Japan, the agency said, adding that higher waves may hit Japan later.
Earlier in the day Japan issued a tsunami advisory, saying waves of up to one metre above normal sea levels may hit eastern Pacific coast regions.
Large areas of the coastline covered by the advisory were also hit by the 2011 quake and tsunami, which killed more than 18,000 people and triggered a nuclear accident in Fukushima.
