Last July 16, people commemorated the 25 anniversary of the 1991 Luzon Earthquake, which devastated central and northern Luzon, and killed at least 1621 people. Much of the damage to infrastructure was a combination of the power of the magnitude 7.8 earthquake and human greed.
At a later date, my clan went out to look at the ruins of the Hyatt Terraces Hotel. Just like the CCP (Christian Colleges of the Philippines) in Cabanatuan City and the Hotel Nevada in Baguio City, their owners added more floors to the buildings that had foundations suited for low rise structures. With all that extra weight, the buildings collapsed when the earthquake struck. becuase of the massive damage wrought by the earthquake, the UAP (United Architects of the Philippines) redrafted the Philippine Building Code, making future designs and architectural expansions better equipped for such disasters.
