Filipino officials say a strong earthquake has rocked the central Philippines, killing at least 43 people and causing widespread damage and power outages.

The U.S. Geological Survey says the 6.8-magnitude quake struck late Monday morning at a depth of 20 kilometers. The quake was centered in a narrow strait just off Negros Island.

Authorities say a landslide killed 29 people, others were killed in buildings and homes that collapsed on Negros, including the seaside town of La Libertad. Dozens of people are missing.

Numerous aftershocks continued to shake the island hours after the quake.

Officials say there is no concern of a tsunami, although some coastal towns nearby were hit by large waves.
