At least four people died and 30 were injured after a major, magnitude 7.3 earthquake shook Indonesia early today, prompting authorities to activate the country's new tsunami warning system.

The quake struck at 1:02 a.m. local time (12:02 p.m. EST yesterday) 85 miles (135 kilometers) northwest of Gorontalo in the country's central Sulawesi region, according to the U.S. Geological Survey. The new tsunami warning system was turned off a couple hours after the quake struck and no cyclone developed, but residents were still panicked and clustered on high ground, the International Herald Tribune reports.

At least four were dead, according to the Associated Press, and thousands of houses and a school collapsed, the IHT says.

A light, magnitude 4.1 quake rattled the San Diego area early this morning, south of where wildfires are raging. The quake hit at 4:35 a.m. local time (7:35 a.m. EST) 52 miles (84 kilometers) north-northeast of San Diego, the Geological Survey says. No damage or injuries were reported, the AP says.
