The 4-5 degree (V-VI) isoseismal was 300 km from the source and included the southeast of Luzon Island, Masbate, and Leyte Islands, and the north of Cebu Island. The boundary of the area of perceptibility was 600 km from the focus and included the south of Luzon Island, the islands of the Visayan Sea, and the northeast of Mindanao Island. At Manila, only a few people, who were at rest, noticed the earthquake. However, water splashed out of two large reservoirs 20-25 m in diameter, possibly because of the resonance oscillations which developed. The earthquake was accompanied by numerous recurrent shocks. Off the low-lying coast of Batag Island, the sea retreated, and then surged in strongly; several fishermen drowned and many fishing boats were sunk.
