Here is an article from El Tiempo, bo Bogota, Columbia, July 31, 1962 that explains what happened at Matthew 27:52-53.
Tombs opened at Jesus Death
The text at Matthew 27:52-53 concerning the memorial tombs [that] were opened as the result of an earthquake occurring at the time of Jesus death has caused considerable discussion, some holding that a resurrection occurred. However, a comparison with the text concerning the resurrection makes clear that these verses do not describe a resurrection but merely a throwing of bodies out of the tombs, similar to incidents that have taken place in more recent times, as in Ecuador in 1949 and again in Bogota, Columbia, in 1962, when 200 corpses in the cemetery were thrown out of their tombs by a violent earth tremor.
