Dr. John Dvorak received his PhD in planetary geophysics in 1979 from the California Institute of Technology in Pasadena, California. That was followed by 16 years working for the U.S. Geological Survey on earthquakes and volcanoes, including the 1980 eruption of Mount St. Helens and eruptions in Hawaii, Alaska, Italy, Central America and Indonesia. Currently, he operates one of the large telescopes at the summit of Mauna Kea in Hawaii. His professional interests are far ranging, including earthquakes and volcanoes, as well as the flaring of comets, what scientific evidence there may be for life outside the solar system, and whether the multiverse can ever be proven to exist.
John Dvorak, Ph.D. has studied volcanoes and earthquakes for the U.S. Geological Survey around the world and has written for various respected science journals. He discussed the ticking tectonic time bomb known as the San Andreas fault, as well as various volcanoes, and the telescope he operates in Hawaii.
