Michael Poland
Mike Poland is a research geophysicist with the Cascades Volcano Observatory and the current Scientist-in-Charge of the Yellowstone Volcano Observatory.
Mike's area of specialization is volcano geodesy, which emphasizes the surface deformation and gravity fields associated with volcanic activity. This work involves the use of space-based technologies, like Interferometric Synthetic Aperture Radar (InSAR), as well as ground-based techniques, like microgravity surveys. Mike has taken part in studies on a variety of volcanic systems in the United States, including Mount St. Helens and other volcanoes of the Pacific Northwest, Kilauea and Mauna Loa volcanoes in Hawaii, and the Yellowstone caldera. His recent work has focused on using gravity change over time to understand the character of the fluids that drive volcanic unrest, and also on the potential of satellite data to improve forecasts of future changes in volcanic activity.

Time series of vertical displacements during April–October 2017 at four GPS stations on the north side of Yellowstone Lake
linkTime series of vertical displacements during April–October 2017 at four GPS stations (LAK1, LAK2, LKWY, and SEDG) on the north side of Yellowstone Lake. Downward trends indicate subsidence and upward trends show uplift. Uplift “spikes” in late September are related to inclement weather and do not show true deformation. Error bars are one standard deviation.
