The USA advised people on their Pacific coastlines to get away from the shore as a precaution against tsunami waves caused by a volcano eruption.

The tsunami advisories mean strong currents and waves are expected, but a major tsunami event is unlikely.  Tsunami waves of 1.2 meters were recorded on one Japanese island.

Earlier a huge underwater volcanic eruption caused waves of more than a meter to crash into Tonga.

The eruption of the Hunga Tonga-Hunga Haʻapai volcano was heard across the South Pacific, and eventually as far away as the USA.

Many parts of Tonga, whose capital is just 65km (40 miles) south of the eruption, are covered in ash and are experiencing a near-total blackout of power, phone lines, and internet services. The extent of any injuries or damage is still unclear.
In Japan, the 1.2m tsunami was recorded in the Kominato district of Amami-Oshima Island in Kagoshima Prefecture at 23:55 (14:55 GMT) on Saturday.
