In the oral traditions of Chile’s coastal regions, particularly among Mapuche communities, there exists a long-whispered legend of ghostly beings that walk the shores before and during catastrophes. These entities had no formal name for centuries - only described in fragments and murmurs passed from survivor to survivor. It wasn’t until the 27F Earthquake in 2010 that a term gained traction: “Muru”, a word meaning complaint or warning in Mapudungun. Survivors, particularly in Talcahuano, Dichato, and Curanilahue, began using this term to refer to the strange, faceless entities seen walking in the waves before the tsunami struck.
