What the record says

NCEI’s account, from the sources it cites.

April 1765. According to handwritten documents of the Convent of Santo Domingo cited by Larde (S. F.), in 1765 there were many earthquakes since March and in San Salvador nobody slept in their homes. On April 14 an earthquake "ruined temples and made other breakdowns in San Cristobal, Ilopango, San Martin Gilotepeque, San Pedro Perulapán, San Bartolome Perulapia, another town and San Juan Cojutepeque". There were landslides in the drainage of Lake Ilopango.

In its catalog, Vassaux (1969) notes for April 20 strong earthquakes that seriously affected the city of Chiquimula causing more than 50 dead and many wounded: subsequently developed a smallpox epidemic that increase the number of victims. The latter event is dated June 20 by Rockstroh (1903) and June 21 by Montessus (1888).
