(CNN) A powerful typhoon killed four people in the Philippines and prompted authorities to close the country's largest airport due to powerful winds and heavy rains.

Typhoon Kammuri, known locally as Tisoy, made landfall on the southeastern part of Luzon, the Philippines' most populous island, on Monday night. It hit as the equivalent of a Category 4 Atlantic Hurricane, packing maximum sustained winds of nearly 215 kilometers per hour (130 miles per hour). Thousands had evacuated ahead of time

Two of the victims were killed by falling trees while two others died when their roofs collapsed, CNN affiliate CNN Philippines reported Tuesday. The deaths were reported by officials in three different provinces -- Oriental Mindoro in the east of the Philippines, Camarines Sur in the west and Zambales in the north.
