Japan islanders sleepless after 900 earthquakes in two weeks
More than 900 earthquakes have shaken a remote and sparsely populated island chain in southern Japan over two weeks, keeping residents anxious and awake all night.
Seismic activity has been "very active" in the seas around the Tokara islands since 21 June, authorities said after a magnitude 5.5 earthquake struck on Wednesday.
There have been no reports of damage and no tsunami warning has been raised but authorities have advised residents to prepare to evacuate if needed.
