Last Updated, Wednesday, 11 a.m. At least 270 people in the Philippines were killed by a typhoon packing 130-mile-per-hour winds on Tuesday, with more than half of the victims from Mindanao island’s east coast, according to a report from the ABS-CBN News Channel in Manila.

A landslide destroyed a Philippines Army base and a flash flood swept away an army patrol vehicle carrying soldiers and civilians, according to the report. Coastal surge created a flash flood that was blamed in the deaths of at least 23 people in the town of Cateel, the authorities said.

A video from 28storms.com. shows scenes of the devastation left by the storm, known locally as Typhoon Pablo, and the storm’s track as it continues to push west away from Mindanao.

For Wednesday, the government’s weather agency, the Philippine Atmospheric, Geophysical and Astronomical Services Administration issued typhoon warnings on its Facebook page and its Twitter account.

TROPICAL CYCLONE WARNING: TYPHOON “#PabloPH” (BOPHA)

ISSUED AT 05:00 AM, 05… //t.co/N0dYA4aX — PAGASA-DOST (@dost_pagasa) 4 Dec 12

Patrick Meier, former director of crisis mapping at Ushahidi, reports on his blog, irevolutionnet. how government officials in the Philippines encouraged Filipinos three days before the typhoon’s landfall to use the #PabloPH hashtag on Twitter.

The government’s official Twitter account, @govph, urged people to also follow weather updates on @dost_pagasa, the official weather service’s Twitter account. It has more than 400,000 followers.

Government officials also offered guidance on the hashtags #rescuePH for rescue and #reliefPH for relief, Mr. Meier pointed out.

Please continue to monitor #PabloPH for updates on typhoon. For relief and rescue, refer to: #reliefPH #rescuePH. Keep safe and informed. — PCDSPO (@pcdspo) 4 Dec 12

Mr. Meier, now director of social innovation at the Qatar Foundation’s Computing Research Institute, said that he and his team would be studying the posts on Twitter to see if the government’s endorsement increased the usefulness of the tweets. During Hurricane Sandy, governors, mayors and other officials along the East Coast used Twitter regularly to provide regular updates to people about the storm.

On Twitter, people shared photos of the devastation in the Philippines, including multiple photos.
