ALERT! TSUNAMI ADVISORY for American Samoa. A hazardous tsunami has been generated by volcanic activity in Tonga. Monitoring is underway to evaluate the threat.

A tsunami warning is now in force for all of Tonga following this evening's violent volcano eruption. There are reports of sirens ringing across Nukualofa and police are asking people to move to higher ground.

UPDATE! Tsunami waves measuring 2 feet in height were observed by sea-level gauges at the capital of the U.S. territory of American Samoa following volcanic activity in Tonga, the U.S.-based Pacific tsunami warning center said.
The tsunami threat continues and sea level fluctuations and strong ocean currents pose hazards along beaches in harbors, the tsunami monitor said in a statement.
