What the record says

NCEI’s account, from the sources it cites.

1787 May 10. A strong shock cracked walls of Guadalupe church at Ponce. Church was later repaired and used again. At San Juan, the cathedral suffered much damage as did the fort and other buildings. People deserted the city in great fear (reference #1189)

1787 May 10. Neumann (1913) is the only source of information for this earthquake. It is not noted in any of the records for the principal earthquake on May 2nd, 1787 and is not noted in any of the correspondence of the Catholic Bishop who was in San Germán on that day. In fact, a communication by the bishop relates a strikingly similar event in San Germán, one so similar that one must doubt the veracity of the report by Neumann (1913) […] We consider this event to be non-existent, and it should be noted as such in any further catalogs. Effects should be referred to event of May 2, 1787. (reference #14050)
