Reaction and response

Compared to the devastating 7.8 M earthquake that occurred in Luzon in 1990, which caused over 2,400 deaths and $695,000 (USD) in damage, the 1999 Luzon earthquake, caused substantially less damage while being of similar magnitudes.Luzon Earthquake, 1990 – Countries & Disasters – International Recovery Platform https://www.recoveryplatform.org/countries_and_disasters/disaster/21/luzon_earthquake_1990 30 November 2021 recoveryplatform.org 25 October 2021 The earthquake caused moderate destruction to buildings and other infrastructures near the epicenter and surrounding areas. There were few casualties and injuries from the event and most of the population received little to no harm from this high magnitude earthquake. Of the six fatalities, only two occurred due to fallen debris while the other four were due to elderly people experiencing heart attacks.
The government took measures to spread awareness to its citizens and enforce individuals to relocate to safer environment as a result of destructive earthquakes that occurred in the years prior.Philippines – Earthquake OCHA Situation Report No. 2 – Philippines 13 December 1999 https://reliefweb.int/report/philippines/philippines-earthquake-ocha-situation-report-no-2 20 October 2021 ReliefWeb Philippines Defense Secretary Orlando S. Mercado attributed the minimal damage and casualties to the government's disaster preparedness program. The Philippine government implemented routine fire and earthquake drills in hospitals and other public establishments following the devastating 1999 Jiji earthquake that occurred earlier that year. As a result, many took shelter and were able to secure locations where they would be more equipped to the earthquake.
