San Mateo County sounded the alarm today, to ensure its coastal communities are ready for a tsunami.

The Office of Emergency Services conducted the first full volume test of its tsunami warning system Wednesday morning.

Sirens wailed for more than two minutes, allowing officials to determine how far away they could be heard.

The first sirens were installed last fall and there are now four of them, in Pacifica, Moss Beach and Princeton.
