The culprit: Sagaing Fault
Earthquake parameters measured by global seismological observatories suggest the earthquake was generated by the Sagaing Fault, the geologic structure that defines the boundary between the Indian Plate and the Eurasian Plate.
The Indian Plate is a continental crust that has been travelling from the south pole since the Paleozoic Era, around 225 million years ago. Moving northwards, it has collided since about 65 million years ago, right about the time the dinosaurs became extinct, with another continental but much larger and stationary crust, the Eurasian Plate to the north. This collision has produced the famous Himalayan Mountain Range that hosts the tallest mountains in the world, Mt. Everest being at the roof.

The recent decision of the Philippine government, through its Department of Environment and Natural Resources (DENR), to rescind its contract with the developer of the Masungi Georeserve in Tanay, Rizal, could put an important geological effort of confirming the inland presence of Paleocene rocks in the Philippines in jeopardy.
Whichever party emerges victorious in this legal battle, the Masungi Limestone as a geological formation must be protected by way of a robust conservation and preservation program.
On August 18, 2020 at the height of the COVID-19 pandemic, Masbate Island in the central Philippines was struck by a magnitude 6.6 earthquake whose epicenter was located in the southern coastal town of Cataingan. This tremor killed at least one individual and levelled off a building near the epicenter. Seventeen years earlier, on February 15, 2003 a magnitude 6.3 tremor struck the same island. The epicenter was located less than forty kilometers to the northwest of the 2020 earthquake, in the town of Uson.
While no one wishes for earthquakes, without them it would be impossible to understand these phenomena and would continue to threaten an unprepared society with their attendant hazards.

July 16, 2024 was the 34th anniversary of an earthquake that devastated major cities in northern Luzon. This earthquake was so powerful that it sent seismic waves that were felt as far as Metro Manila, located more than a hundred kilometers from the epicenter.
On the afternoon of July 16, 1990, a Monday, a magnitude 7.8 earthquake struck northern Luzon with an epicenter located near the town of Rizal in the province of Nueva Ecija. More than 1,500 individuals perished while infrastructure damage was estimated at more than 12 billion Philippine pesos (>USD 200 million).
