Japan urged to provide earthquake tips to tourists amid surge in travel cancellations
A vast swathe of southern Japan – from the islands of Okinawa in the south to the mouth of Tokyo Bay – is on heightened alert after a magnitude 7.1 earthquake struck off the east coast of Kyushu on August 8. Experts have cautioned that the tremor may have been the precursor to a far larger quake in the Nankai Trough, a 900-km offshore fault.
