MANILA - (UPDATED) A magnitude 5.1 earthquake rattled Leyte province early Wednesday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.

The tremor struck 5 kilometers northeast of Albuera, Leyte at 6:26 a.m., the agency said in its website.

With a depth of 5 kilometers, the tremor was felt at Intensity 5 in the neighboring town of Ormoc and Albuera, Intensity 4 in Pastrana, and Intensity 3 in Tacloban City and Palo.

"The epicenter is inland and would not be generating any tsunami in the Leyte area. We are verifying if there were significant effects near the epicenter. So far, we have obtained in our unofficial report there were some areas that have suffered some damages but these need to be verified," Phivolcs director Renato Solidum told radio DZMM.

Phivolcs describes Intensity 5 as "strong." This intensity may cause shaking throughout buildings and may make hanging objects swing violently.

Intensity 4 meanwhile is described as "moderately strong." It can be felt like the passing of a heavy truck and can rattle wood-framed buildings, the agency said.

Phivolcs warned residents of aftershocks.

State seismologists have also received reports that a structure collapsed in Albuera.
