quake

In California, where the next “Big One” is an always-looming threat, some lessons learned from the 1925 Santa Barbara quake resonate even 100 years later, experts say.

Supershear quakes send intense shaking farther from the epicenter and strike twice, according to Elbanna -- a sharp initial blow from the shock front followed by the trailing waves.

The destruction came less than two weeks after a 6.9-magnitude quake struck the central Philippine island of Cebu, killing 75 people and wrecking about 72,000 houses.

The 6.9-magnitude quake struck just before 10 p.m. local time Tuesday in the waters off Bogo City on the island of Cebu, according to the U.S.

In Mati city, close to the offshore epicentre of both quakes, the latest one knocked out power.
