Answer 2

After the Arenal Volcano erupted in 1968, a popular myth emerged that it was, in fact, a dormant volcano, but the government had secretly detonated it to attract tourists. Another myth suggested that the volcano's eruption was triggered by a wealthy landowner who built his house on top of it and disturbed its energy. These myths have been debunked by scientific explanations of the volcano's eruption.
