Was in a penthouse on top of a 20 storey office building in Salcedo Village, Makati, in 1990 when we had the 7.8 one. Certainly gets the adrenaline pumping, as you leap 10 steps at a time, down emergency stairs, partially blocked with 10 years worth of offices' trash. managed to get to the exit just as the first aftershock hit, good times.
