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.

About half a million years ago, a large rhyolite lava flow erupted. Over time, hot water and gases heated by the magma chamber rose through faults in the lava flow.

In fact, the most common form of eruptive activity at Yellowstone is a lava flow, and even those aren't that common. They happen only once every few tens of thousands of years.
