"Prompting unfounded fears of a megatsunami." The backstory of the megatsunami theory is interesting. It seems based on two observations, sheer cliffs on the islands, and big blocks of limestone displaced a thousand miles away. (Cue ancient aliens theme, how did stone blocks get moved?) So the theory is that past eruption(s) caused landslides which triggered tsunamis. It could happen, but some are skeptical. https://blogs.agu.org/landslideblog/2016/09/20/canary-islands-megatsunami/
