Ray Dibble has nearly 50 years of experience in the field of seismology and has been active in both seismic research and instrumentation development. He is responsible for the Mount Erebus, Antarctica seismic array and data transmission as a guest seismologist with the Mount Erebus Volcano Observatory. He has contributed microphones, television surveillance equipment and the digital seismic recorder to the Erebus system.
Dibble pioneered seismic power recording at volcanoes from slow speed tape recordings and installed a real-time seismic power recorder, which gave warnings of the 1968 eruptions of New Zealand's Ruapehu Crater Lake by using pattern recognition. His development of a slow-speed tape seismograph for volcano-seismic research has been copied by Geotech, USSR Academie of Science, Australian National University, Hawaii Institute of Geophysics, Hokkaido University for its seafloor seismographs. Dibble discovered the abnormally high upper-mantle velocities under New Zealand while determining epicenters of New Zealand earthquakes in the 1950's.
Dibble received his BS (1951), MS (1955), and Ph.D. (1972) degrees in geology from Victoria University of Wellington. He was a lecturer/reader in applied geophysics at Victoria University of Wellington from 1965-1992, a visiting associate professor at the University of Hawaii (1970-1971), at invited scientist at the University of Tokyo (1984-1985), a J.S.P.S. Fellow at Sakurajima Volcano Observatory (1987-1988), senior scientist at the Geophysics Division, DSIR, New Zealand (1947-1965), and a guest seismologist at the Crary Science and Engineering Laboratory in McMurdo, Antarctica (1993-1998). Dibble was on the editorial board for the Bulletin of Volcanology and Journal of Geothermal Research (1975-1991), a leader of the IAVCEI Working Group on Mitigation of Volcanic Disasters (1980-1989), and a member of the UNESCO Hazard Assessment Team at Azores (1989). He has published over 20 peer-reviewed journal articles.
