Chilpancingo, in Guerrero, was badly shattered in 1902, and in 1907, and in 1909 was reduced to a mass of ruins.
The earthquake shocks of the 30th and 31st of July 1909 were unusually severe throughout southern Mexico, reducing Acapulco and Chilpancingo to ruins and shaking the city of Mexico severely.
The capital, Chilpancingo, or Chilpancingo de los Bravos (pop. 7497 in 1900), is a small town in the Sierra Madre about 110 m.
Chilpancingo was badly damaged by an earthquake in January 1902, and again on the 16th of April 1907.
