Central Pichilemu was not severely damaged by the earthquake, but the tsunami caused significant destruction. The Fisherman Creek, located in front of the beach, was completely destroyed, and its machines are now unusable. Most of the Agustín Ross architecture that characterized the city, three of them being National Monuments of Chile, were damaged. The Agustín Ross Mirador, a famous location in front of the beach, located less than 200 meters from the Fisherman Creek, was completely destroyed. Its famous balustrades were washed away or thrown asunder. Many restaurants, kiosks and a circus were affected by the tsunami.
The rural parts of Pichilemu, like Ciruelos, Rodeillos and Espinillos feature houses constructed from adobe. Many were more than 100-years old, and were destroyed or are now uninhabitable.
The most powerful aftershock was produced almost 40 kilometers in front of the coast of Pichilemu, at the 03:10 local time (07:10 UTC) in March 2, with an intensity of 5.5 in the Richter scale, according to the USGS.
The Intendant of the O'Higgins Region, Juan Núñez, had a meeting with the Governor of the Cardenal Caro Province, Loreto Puebla, the Mayor of Pichilemu, Roberto Córdova, and naval and military authorities, juntas de vecinos representatives. They decided to leave the Carabineros police force to maintain the security of the city.
