"All of them were already sent home after receiving treatment from the hospital," Bernos said as she noted no one was confined in a hospital.

Bernos said no hospitals that were damaged and noted most of the affected structures are school buildings and churches.

"In our school buildings, 58 school buildings were damaged and the most affected is the Pulot National High School. Maybe it cannot be used anymore. It is located at Lagayan, Abra in the epicenter and most of our damaged houses were from Lagayan,'' added Bernos.

"We have initially 40 damaged houses, six totally damaged and I think 30 plus were partially damaged," she added.

Bernos said all "major national roads" that were affected by rockslide and landslide were cleared and passable.

The power supply in seven towns that experienced power outage since the tremor occured around 10:59 pm of Tuesday were restored as of 12:10 am on Wednesday.
