Tectonic Plates

Based on the NOAA map of tectonic plates we can see that the Philippines is in close proximity to multiple plate boundaries. These plates are the Philippine Sea Plate, Indo-Australian Plate, and the Eurasian Plate.

The plate tectonic movement near the Philippines is what creates such a high chance for disaster. Since the Philippines is located in the Southeast Asia part of the Pacific Ring of Fire. Where the plates meet and the volcanoes surround the Philippines there is an overlap of convergent boundaries. This overlap of convergent boundaries is called a subduction zone. Specifically significant to the Philippines is the Philippine Sea Plate because it is moving towards the Eurasian Plate at a rate of  "6-8 cm/year". The subduction causes earthquakes, volcanic activity, and more. 

It is interesting as to why the Eurasian Plate is being subducted under the Philippine Sea Plate since it is mostly continental crust. This also explains why there is the philippine fault. If the fault slips it will cause a devastating disaster.


 
Overall the chance for disaster in the Philippines is very high due to the mass movement of tectonic plates and the convergence of multiple plate boundaries.

  1. This was a great tectonic setting reflection. Looking forward to what you'll discover in the upcoming weeks!
