Two earthquakes struck off the coast of Mindanao, Philippines, and generated a large tsunami on 17 May 1992. They measured 7.1 and 7.5, respectively on the moment magnitude scale and were spaced 26 minutes apart. Seismic shaking and a tsunami caused damage in Manay, Cateel, Baganga, Boston, Caraga and Tarragona, Davao Oriental Province. At a cove in Manay, the tsunami measured and flooded about inland as a result of the amplification effect. Following the first shock, many residents at the cove fled the area after the first earthquake and tsunami, however, a child was killed in the wave. Wave heights of or higher were recorded along the coast of Caraga and Manay. Residents at the coast said the tsunami arrived about 2 to 10 minutes after the first event with the first wave also the largest. Both events occurred on a fault where the Philippine Sea plate subducts beneath the island, with epicenters apart.
