Figure 1From: Characteristics of dilatational infrasonic pulses accompanying low-frequency earthquakes at Miyakejima Volcano, JapanLocations of seismic and infrasonic stations of the Japan Meteorological Agency at Miyakejima Volcano, Japan. Solid squares represent three-component short-period (1Â Hz) seismic stations. Solid triangles indicate the locations of infrasonic microphones. Solid circles are the locations of high-resolution cameras which are able to visualize the volcano even at night. Shaded area indicates the summit caldera that formed in 2000.Back to article page
