Philippines Earthquake Review – In the first 6 months of 2019 we recorded 5065 earthquakes. The big majority, 4818, were weak vibrations with a magnitude of less than 3.0. But 5 quakes were really strong with magnitudes of 6 or greater.

The strongest one happened on April 23 around 1:37 p.m. off the eastern coast of Samar. Fortunately its focus laid deep in the crust at a depth of 61 kilometers.

We put the left side map because the right side heat map doesn’t clearly show the shape of the country. You may click on the maps to enlarge them. Better is to visit the interactive maps on this page.

Why we use heat maps

PHIVOLCS always publishes an overview map associated to each recorded earthquake.

Up until coming here full time last year I had experienced 2 earthquakes in the previous 34 years. In the last 9 of those 34 years I have spent varying times in the Philippines. The 2 earthquakes were both felt in Ontario.

This last month or so I have now lost count of the number we’ve had. The biggest was a 4.4. Sometimes we have had 3 or 4 in a day. 

The epicentre of the 4.4 was only a few miles away from the house and a mile or so down. The house shook and a book fell off a shelf. Since the scale, as I understand it, is logarithmic, I’d prefer not to experience anything above a 5!

My personal experience is that seismic activity in the Masbate area has increased (fairly significantly) lately. It would be nice if PhilVolcs put those 5000 odd events in the six months into some sort of context.
