Volcanoes of Galapagos Islands
About 50 major eruptions have been observed in the Galapagos Islands, making it one of the most volcanically active regions in the world. There is about one eruption every 3 years. Volcanoes of the Galapagos Islands show a pattern of circumferential and radial eruptive fissures, which is rarely seen at other volcanoes. Galapagos shield volcanoes lack dominant rift zones which is present in Hawaiian volcanoes.
