Earthquake February 6 2012

A magnitude 6.9 earthquake rocked the island of Negros at 11: 49 AM this morning, with lesser shocks experienced in Iloilo and Cebu. The earthquake was felt up to Bicol region, Mindoro Island, and Mindanao. As of post time, aftershocks are still felt here in some areas ranging from 4.5 to 5.8. 

Here in Iloilo City, malls and offices were immediately evacuated and classes were suspended. The streets of down town Iloilo City were full of people who moved out of the establishments along the way. Hospitals such as St Paul’s also evacuated their patients. The coal power plant located at La Paz automatically shut down which led to city-wide brownout immediately during the quake.

Damages in structures here in Iloilo were minimal, with small cracks reported at some shopping malls and buildings. No casualty was reported here in the city. The National Disaster Risk Reduction and Management Council (NDRRMC) reported about 13 casualties while about 40 missing due to landslide in other regions.

Editor’s Note:

I was at DTI Regional office at JM Basa when the quake hit. We calmly evacuated the building while waiting for the quake to end. The initial jolt took about 30 to 40 seconds. You could see the water at the pavement violently swaying. After the quake finished, we ended our transaction at the office and headed at the Assumption School to take my niece. Along the way, while I was driving at JM Basa, at about 12:20 PM, a strong but shorter aftershock was felt. Schools, businesses, the city and provincial capitol offices were suspended for the rest of the day. And as more people rushed to go home, traffic ensued at Iloilo City central business district area.

7:34 PM: As I’m writing this post a strong aftershock struck again. I’m posting this while a slow swaying is rocking me.
