Reports say a low, rumbling sound heard by generations of lighthouse keepers for decades may have a natural explanation. Accounts describe the noise as deep and eerie, carrying across distances of up to several miles and sometimes felt through the structures of nearby buildings, not just heard. Fishermen have also reportedly been confused by the noises, which appear to occur under circumstances that are not clearly connected to human activity. One theory mentioned is that the sounds could be produced by humpback whales, potentially associated with breathing or “sneezing”-type vocalizations. The reports do not cite definitive confirmation that whales are the source, and alternative explanations are not detailed in the provided material. Overall, the story presents the persistent sounds as a long-running local mystery and frames the whale hypothesis as a possible reason for the frequency, reach, and the way the rumbles can be physically felt.
