In short: On July 16, 1990, a massive tremor tore through Luzon Island, lasting nearly a full minute. Baguio City, perched high in the mountains, bore the brunt of the destruction. With roads severed by landslides and the airport damaged, the city remained cut off from the rest of the country for days.

The earthquake struck at 4:26 p.m., with its epicenter located in the Nueva Ecija province. Measuring 7.7 in magnitude, the tremor caused widespread devastation across Luzon, the largest island in the Philippines. Baguio City, a popular mountain destination, suffered the most severe damage as the shaking triggered landslides that blocked all three main access roads. This isolation left the city unreachable by ground transport for three days, forcing residents to rely on limited helicopter access to Loakan Airport for evacuations and aid.

The human toll was immense, with estimates suggesting at least 1,000 people were killed and another 1,000 seriously injured. Buildings across the region collapsed, including schools, factories, and hotels. In Baguio, the Hyatt Terraces Baguio Hotel became a site of both tragedy and survival; while dozens perished, three individuals were miraculously pulled from the rubble after being trapped for 11 to 14 days. These survivors endured by consuming rainwater or their own urine, with one recovery setting a world record for entombment duration at the time.

Baguio sits atop at least seven fault lines, making it exceptionally vulnerable to seismic activity. The 1990 event highlighted the city's precarious geography, where heavy annual rainfall further exacerbates the risk of landslides. The disaster was compounded by frequent aftershocks that terrorized the population, leading most of the city's 100,000 residents to sleep outdoors in tents or streets for the following week. The area's vulnerability was underscored less than a year later when Mount Pinatubo erupted, an event some geologists suspect may have been linked to the tectonic instability of the period.
