Magnetism on Rapa Nui
Among the sites most visited for their supposed magnetism are the large oval rock called Te Pito Kura and a section of the road to Anakena, about half a kilometer from the beach. Illusion or reality? What do the scientists say?

Recently, it has been shown that some magnetic anomalies are not of geological origin nor have they been generated by natural remanent magnetism, but directly produced on the surface by natural or man-made causes, among which could be: (1) fires, both naturally occurring and those set by humans, which could significantly alter the magnetism in the soil; (2) the presence of magnetotactic bacteria in the soil; and (3) direct action from rain or run-off water carrying sediments and enriching the soil with magnetic minerals.
In the sand of Rapa Nui there are animals so small that they can hardly be seen with the bare eye. You need a microscope to see them. These animals live in the small spaces between sand grains.
