While the overlap in affected areas is significant relative to the 1837 earthquake, the 1737 earthquake may have occurred slightly more to the north. The earthquake was felt in Concepción but most damage occurred in the towns of Valdivia and Castro, Chiloé Archipelago. In both of these locations churches were destroyed by the earthquake. In addition the Valdivian Fort System and the Royal Storehouse of Valdivia took heavy damage. Landslides occurred next to Villarrica, Calafquén, and Riñihue lakes. Over all this indicates the rupture zone was about 640 km long, with most damage being concentrated in the middle section (Valdivia). There is no evidence the earthquake would have produced a tsunami.
