Tsunami and earthquakes can happen anytime around the Pacific Ring of Fire - from California up and around Alaska down through Japan, Taiwan, the Philippines and Indonesia. The Philippines is no stranger to earthquakes - the Philippine archipelago was largely created by the tectonic squabble between the Eurasian and Pacific plates, forming the Philippine Plate as a distinct entity.
Latest Philippines Earthquake Activity 21-Sep-2019

Latest earthquake activity near Metro Manila: 13th September, 2019, magnitude 5.2, at 08:28:15 GMT (16:28.15 local), location 14.983°N 122.205°E approximately 17km E of Carlagan, Quezon, depth 32KM, felt in Metro Manila as magnitude 2.5, most people did not notice it except in high-rise buildings; there have been aftershocks. Full details: earthquake info from USGS website.
The majority of Philippine earthquakes occur somewhere near the Philippines' Pacific East coast (especially the East coasts of Mindanao & Samar), where a significant tectonic subduction zone has created the second deepest ocean trench in the World - named the Philippine Deep or the Philippine Trench - with a depth greater than 34,000 feet! On 31st August, 2012, this area of the Philippines received a 7.6 magnitude earthquake along the Philippine Trench, East of Samar Island.
Just as in California, U.S.A., a measurable earthquake in the Philippines (greater than Magnitude 2.5) occurs almost every day somewhere, but most people are completely unaware of them - in the ten years from 2008 to 2015 only three earthquakes were felt slightly in Metro Manila, all three earthquakes resulted from seismic activity in the West Philippine Sea, along the geological fault that runs North - South off the West coast of Zambales province. It is rare to have an earthquake in the Philippines that measures greater than Magnitude 6.0.
The last significantly destructive earthquake in the Philippines occurred on 15th October, 2013, beneath the West coast of Bohol Island. The Bohol earthquake was measured as Magnitude 7.2 causing substantial damage across the island, and cited as the cause of 222 fatalities. Damage was apparent to buildings in the provinces of Bohol and Cebu.
Remember: earthquakes do not kill - buildings kill; explore the Philippines' beautiful beaches, rivers, mountains and rain forests, instead of its cities.
The Marikina Fault
The most significant, historic earthquake zone (geological fault) in the Philippines is located just 10km East of Manila City and is known as the "Marikina Valley Fault".

Tsunami in the Philippines are extremely rare.
The last measurable tsunami in the Philippines affected the northern and the eastern seaboards on 11th March, 2011. In that event, tsunami waves of around half a meter, resulting from a relatively shallow and very large 8.9 magnitude earthquake off the coast off Miyagi prefecture, Honshu, Japan, arrived in the early evening and caused little or no damage, and no loss of life.
Prior to March 2011, the last recorded tsunami in the Philippines, that actually caused loss of life, occurred in the Verde Island Passage (between Batangas & Mindoro Island, affecting Puerto Galera) in the early morning of 15th November 1994, originating from a 7.1 magnitude (Richter) earthquake, 11 KM West of the Baco Islands, according to the Philippine Institute of Volcanology and Seismology. The tsunami waves, resulting from the 7.1 magnitude earthquake, were measured at 6 meters in many areas when they reached land, but up to 8.5 meters in a few locations (primarily the Baco islands) where the bathymetry was favorable; the tsunami waves reached up to 250 meters inland in areas that faced the earthquake epicenter. The death toll was 41 people.
