MANILA, Philippines — Typhoon Fung-wong blew out of the northwestern Philippines on Monday after setting off floods and landslides, knocking out power to entire provinces, killing at least 10 people and displacing more than 1.4 million others.

The typhoon was forecast to head northwest toward Taiwan.

Fung-wong lashed the northern Philippines while the country was still dealing with the devastation wrought last week by Typhoon Kalmaegi, which left at least 232 people dead in central provinces on Nov. 4 before pummeling Vietnam, where at least five were killed.

Fung-wong slammed ashore in northeastern Aurora province on Sunday night as a super typhoon with sustained winds of up to 115 mph and gusts of up to 143 mph.

The 1,100-mile-wide storm weakened as it raked through mountainous northern provinces and agricultural plains overnight before blowing away from the province of La Union into the South China Sea, according to state forecasters.

At least 10 people died due to flash floods, landslides, exposed electrical wires and a collapsed house in the provinces of Catanduanes, Eastern Samar, Nueva Vizcaya, Mountain Province and Ifugao, disaster-response and provincial officials said.

Among the dead were three children who were hit by two separate landslides in the mountainous province of Nueva Vizcaya, police told The Associated Press, adding four others were injured.
