| Abstract;In October 2005, seismic exploration using artificial sources was conducted at Suwanosejima volcano where Strombolian or Vulcanian eruptions have been frequently repeated. In addition to 9 permanent stations, 88 temporal stations equipped with a 2 Hz vertical component seismometer and portable data loggers were deployed on Suwanosejima Island. Dynamite shots with charges of 24 kg were detonated at 8 locations in the sea around the island and one in the crater formed by the 1813 eruption. Seismic signals were successfully recorded. To reveal the P-wave velocity structure, 786 arrival times of the first motion were picked from the seismograms, and 486 and 250 were classified into ranks A and B. (author abst.) |
