Two earthquakes struck off the coast of Mindanao, Philippines, and generated a large tsunami on 17 May 1992. They measured 7.1 and 7.2, 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 6 m (20 ft) and flooded about 200 m (660 ft) 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 3 m (9.8 ft) 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 20 km (12 mi) apart.
