Indonesia is one of the world's most volcanically influenced regions. This is due to the special location of the archipelago: the more than 17,000 islands and islets lie in a semicircle along the important tectonic interface between the Pacific Plate and the Indian-Australian and Eurasian Plates.
Indonesia and its volcanoes are therefore part of the "Ring of Fire," the circum-Pacific fire belt. This special location leads to the fact that there are numerous jaspers of volcanic origin on the Indonesian islands, or jaspers whose components are due to volcanic activity.
