Lomnitz (2004) describes this event as follows:
"The city was located at its initial site fronting the Bay of Talcahuano, near the present location of Penco. The effects of the shock were comparable to those of the 1835 earthquake. The epicenter was probably offshore and there was a major tsunami. The initial pulse of the tsunami was upward and the population took heed and escaped to high ground. No Spanish settlers were killed. "
