Landmark Historical Earthquakes in Manila
Significant seismic benchmarks, cataloged damage, and engineering lessons shaping modern safety standards.
Castillejos, Zambales
Strong crustal tremor that shook Metro Manila skyscrapers violently, causing rooftop swimming pool waters to slosh and cascade over tower edges in widely broadcast footage; suspended the Manila LRT and MRT networks, damaged runways at Clark International Airport, and caused 18 deaths in Central Luzon.
Luzon (Digdig Fault) / Cabanatuan
Killed over 1,600 people in Baguio and Cabanatuan, damaged bridges and hotels in Manila, and prompted modern seismic zoning in the Philippines.
Seismic Geology & Soil Amplification in Manila
Plate boundaries, tectonic kinematics, and local geotechnical ground response characteristics.
Metro Manila sits on the isthmus between Manila Bay and Laguna de Bay in the Philippine Mobile Belt. It is directly bisected by the West Valley Fault—a 100 km active strike-slip structure capable of generating "The Big One" (M 7.2) across the capital region.
Local Soil Profile & Ground Motion Resonance
Manila is underlain by the Guadalupe Formation (volcanic tuff) in Quezon City, but coastal areas along Manila Bay and Pasig River alluvium consist of water-saturated sand and clay with extreme liquefaction hazard.
Major Active Fault Systems Near Manila
Seismogenic fault lines, maximum credible magnitudes (MCE), and proximity to the metropolitan center.
West Valley Fault (Marikina Valley Fault System)
Runs directly through Quezon City, Marikina, Pasig, Makati, Taguig, and Muntinlupa; last ruptured in 1658 (recurrence ~400–500 yrs).
Seismic Safety, Observatory & Building Codes
Official seismological monitoring, building construction standards, early warnings, and emergency response.
Frequently Asked Questions About Earthquakes in Manila
Authoritative answers to common questions regarding seismic risks, building safety, and preparedness in Manila.
What is "The Big One" in Metro Manila?▾
PHIVOLCS models "The Big One" as an M 7.2 rupture of the West Valley Fault slicing through Metro Manila, projected to cause severe shaking and thousands of casualties in high-density informal settlements.
