The Philippines has scrambled to deal with multiple calamities wreaked by four back-to-back typhoons and storms in less than a month.

Devastating floods struck the northern Philippines on Monday, when Tropical Storm Toraji became the fourth tropical storm to hit the island nation in three weeks.

A river swollen from Typhoon Toraji rains swallowed homes in a northern province in the Philippines. Aerial footage shows the Cagayan River swallowing swathes of farm and residential land in Cagayan province on2.
