New "Geological Maps of Volcanoes", Miyake Jima Volcano and Iwate Volcano, were published. The series of "Geological Maps of Volcanoes" shows geological maps and eruption history of active volcanoes in Japan. These new maps discribe new distributions of volcanic ejecta, craters and the development history of the Miyake Jima(Miyake-Jima) and Iwate volcanoes. We hope these maps will help those who are intersted in volcanoes, and will be useful to reduce damage from volcanic disaster.
