April 15, 1907 Earthquake: Guerrero, Mexico

April 14, 1907, 23:31 [local time]. There was a destructive earthquake with source near San Marcos, covering a large part of Mexico. The earthquake began with comparatively weak oscillations, which then became strong tremors. The oscillations were so strong at Mexico, that sleepers awoke and ran to the street, the beams of buildings shook, and electrical and telegraph wires in the street became entangled. Several buildings and walls collapsed. The oscillations lasted about 2 minutes. Several new huts, woven of branches, collapsed at San Marcos: mongooses were thrown from trees to the ground. The majority of stone

homes were destroyed at Ayutla and eight persons were killed. At Acapulco, the buildings suffered only slight damage. The water left the Chacalapa lagoon situated on the coast south of San Marcos; the cabins with baths here were buried in the sand to a depth of 1 1/2 m; large trees fell. During April, numerous recurrent shocks were felt in the epicentral zone. After the earthquake, the sea rushed onshore on the entire stretch of road from Acapulco to Tecuanapa road, which served as a port for the city of Ometepec.
