Earthquake hits Manila, large number of casualties

The title of this post could be the next big head line in newspapers and News-TV shows all over the world.
According to Philvolcs, the Philippine Seismological Observation Institute, the Philippines should prepare itself for a large earthquake of magnitude 7.2. East of the metropolis is the West Valley Fault, an area of about 100 km, and this fault line is expected to be the cause of the next big earthquake in the region.

Almost every day there are earthquakes in the Philippines, whole year round. Many of them are not even felt. Check this page of Philvolcs for the latest ones. In a way the Philippines has learned to live with calamities of all kind. Everybody knows the typhoons in the Philippines, every year. And the flooding of many streets and areas after heavy rain is also something they are used too. These things are only getting headlines when many lives are ended like Typhoon Yolanda last year and several others.

Earthquake warning

Earthquakes cannot be predicted unfortunately, so it is also difficult to be prepared for it. Yet Philvolcs is warning the Government and the people that in our life time a major earthquake might hit Manila and surrounding areas.
After the devastating earthquake recently in Nepal, Philvolcs has published an interactive map of the West valley Fault as an overlay on Google Earth. Check the picture next to this post or check the maps in Google Earth directly by clicking Mirror1 or Mirror2.

Philvolcs director Renato Solidum Jr. says: “The fault has moved four times in the past 1,400 years. On average, it moves every 400 years, ± 10 to 100 years, maybe. The last time an earthquake occurred along the West Valley fault was in 1658, around 355 years ago. So it can happen within our generation or the next generation.”

Prepare yourself

Thus a possible 7.2 earthquake looms around the corner of the West Valley Fault. The earthquake can occur anywhere along the West Valley Fault, including Metro Manila. But a 7.2 magnitude earthquake can shake the ground even a hundred kilometers away, which means that it can shake the whole of Metro Manila and its surrounding provinces.
If such Earthquake hits the area with a magnitude 7.2 there will be many casualties. Estimates are that around 35.000 people will die mostly because of bad construction of houses and buildings.
The Metro Manila area is home to over 25 million people and Manila is one of the most densely populated places in the world.
Infrastructure will be heavily damaged as well. There are many bridges in the Metro and a SkyWay system (a high way above the normal high way). There are the LRT and MRT, trains running through the metro, many parts high above ground level. If all these will be strong enough to withstand a strong earthquake, only time will tell… Costs of damages might be in the trillions of pesos.

My wife and I are living in this area, just around 5 km from the fault line. We do not have high buildings in our neighborhood but we have to be prepared for the worst. Water and electricity probably will be disconnected for a longer time, infrastructure destroyed or impossible to use.

      Hi Hersie,
      Thanks for reading.
      All over the area, drills are held from time to time, so people are aware what might happen sooner or later.
