Puerto Chacabuco VII Puerto Aisén VII Coihaique VI Balmaceda V Cochrane IV Ground effects On the mountains around the fjord, the earthquake caused landslides that in turn created waves as high as fifty meters, which severely damaged some salmon aquaculture installations. The potable water systems of the cities of Puerto Chacabuco and Puerto Aisén were broken, forcing firefighters and the army to supply water. The electricity network of Puerto Chacabuco was also cut off. Aftermath Despite protests against the government organized by Aysen's mayor, Chile's president, Michelle Bachelet, visited the affected zone. She was met with black flags, and, during the protest, Aysen's mayor Óscar Catalán was arrested. Catalán had been heavily critical that the region had not received the necessary help to prevent damage and casualties, as the swarm had been active since January.
