Tsunami Warning/Advisory
The 7.4Mw quake struck at a depth of 10km and created a tsunami which reached a height of about 3m (10 feet) in at least a dozen locations around Japan’s coastal areas
JMA said on its Website:
Tsunami Observations
As of 05:40 JST (UTC+ 9 hours)
At some parts of the coasts, tsunamis may be higher than those observed at the observation sites.
The tsunamis can become higher from now on.
However, JMA later downgraded the warning to a tsunami advisory for the area.
