Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, debunks the misconception that if Yellowstone were to erupt, it would be Armageddon. 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.
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.

Towards coordinated regional multi-satellite InSAR volcano observations: Results from the Latin America pilot project
Within Latin America, about 319 volcanoes have been active in the Holocene, but 202 of these volcanoes have no seismic, deformation or gas monitoring. Following the 2012 Santorini Report on satellite Earth Observation and Geohazards, the Committee on Earth Observation Satellites (CEOS) developed a 4-year pilot project (2013-2017) to demonstrate how satellite observations can be used to monitor larAuthorsMatthew Pritchard, Juliet Biggs, Christelle Wauthier, Eugenio Sansosti, David W.

Lara, Michael P. Poland, Simona ZoffoliA retrospective look at the February 1993 east rift zone intrusion at Kīlauea volcano, Hawaii
The February 1993 dike intrusion in the East Rift Zone (ERZ) of Kīlauea Volcano, Hawai'i, was recognized from tilt and seismic data, but ground-based geodetic data were too sparse to constrain the characteristics of the intrusion. Analysis of Interferometric Synthetic Aperture Radar (InSAR) from the Japan Aerospace Exploration Agency (JAXA) JERS-1 satellite reveals a maximum of ~30 cm of line-of-sAuthorsSarah Conway, Christelle Wauthier, Yo Fukushima, Michael P. PolandContinuous gravity and tilt reveal anomalous pressure and density changes associated with gas pistoning within the summit lava lake of Kīlauea Volcano, Hawaiʻi
Gas piston events within the summit eruptive vent of Kīlauea Volcano, Hawai‘i, are characterized by increases in lava level and by decreases in seismic energy release, spattering, and degassing. During 2010–2011, gas piston events were especially well manifested, with lava level rises of tens of meters over the course of several hours, followed by a sudden drop to preevent levels. The changes in lAuthorsMichael P. Poland, Daniele CarboneMass addition at Mount St. Helens, Washington, inferred from repeated gravity surveys
Measurements of subtle changes in the Earth’s gravityfield can provideinformation on the addition/loss of mass (e.g., magma or aqueousfluids) beneath a volcano. In this study, wemeasured gravity at Mount St. Helens from 2010 to 2016 to investigate possible mass changes followingthe 2004–2008 dome-forming eruption.

Diefenbach, Jeff WynnAbundant carbon in the mantle beneath Hawai`i
Estimates of carbon concentrations in Earth’s mantle vary over more than an order of magnitude, hindering our ability to understand mantle structure and mineralogy, partial melting, and the carbon cycle. CO2 concentrations in mantle-derived magmas supplying hotspot ocean island volcanoes yield our most direct constraints on mantle carbon, but are extensively modified by degassing during ascent. HeAuthorsKyle R. Anderson, Michael P. PolandVolcano Geodesy: Recent developments and future challenges
Ascent of magma through Earth's crust is normally associated with, among other effects, ground deformation and gravity changes. Geodesy is thus a valuable tool for monitoring and hazards assessment during volcanic unrest, and it provides valuable data for exploring the geometry and volume of magma plumbing systems. Recent decades have seen an explosion in the quality and quantity of volcano geodetAuthorsJose F. Fernandez, Antonio Pepe, Michael P. Poland, Freysteinn SigmundssonVolcano geodesy in the Cascade arc, USA
Experience during historical time throughout the Cascade arc and the lack of deep-seated deformation prior to the two most recent eruptions of Mount St. Helens might lead one to infer that Cascade volcanoes are generally quiescent and, specifically, show no signs of geodetic change until they are about to erupt. Several decades of geodetic data, however, tell a different story. Ground- and space-bAuthorsMichael P. Poland, Michael Lisowski, Daniel Dzurisin, Rebecca Kramer, Megan McLay, Benjamin PaukThe spectrum of persistent volcanic flank instability: A review and proposed framework based on Kīlauea, Piton de la Fournaise, and Etna
Persistent motion of the south flank of Kīlauea Volcano, Hawai'i, has been known for several decades, but has only recently been identified at other large basaltic volcanoes—namely Piton de la Fournaise (La Réunion) and Etna (Sicily)—thanks to the advent of space geodetic techniques. Nevertheless, understanding of long-term flank instability is based largely on the example of Kīlauea, despite theAuthorsMichael P. Poland, Aline Peltier, Alessandro Bonaforte, Giuseppe PuglisiThe added value of time-variable microgravimetry to the understanding of how volcanoes work
During the past few decades, time-variable volcano gravimetry has shown great potential for imaging subsurface processes at active volcanoes (including some processes that might otherwise remain “hidden”), especially when combined with other methods (e.g., ground deformation, seismicity, and gas emissions). By supplying information on changes in the distribution of bulk mass over time, gravimetryAuthorsDaniele Carbone, Michael P. Poland, Filippo Greco, Michel DiamentJoint analysis of geodetic and earthquake fault-plane solution data to constrain magmatic sources: A case study from Kīlauea Volcano
A joint analysis of geodetic and seismic datasets from Kīlauea Volcano during a period of magmatic unrest in 2006 demonstrates the effectiveness of this combination for testing and constraining models of magma dynamics for a complex, multi-source system. At the end of 2003, Kīlauea's summit began a four-year-long period of inflation due to a surge in magma supply to the volcano. In 2006, for the fAuthorsChristelle Wauthier, Diana C. Roman, Michael P. PolandInsights into shallow magmatic processes at Kīlauea Volcano, Hawaiʻi, from a multiyear continuous gravity time series
Continuous gravity data collected near the summit eruptive vent at Kīlauea Volcano, Hawaiʻi, during 2011–2015 show a strong correlation with summit-area surface deformation and the level of the lava lake within the vent over periods of days to weeks, suggesting that changes in gravity reflect variations in volcanic activity. Joint analysis of gravity and lava level time series data indicates thatAuthorsMichael P. Poland, Daniele CarboneDome growth, collapse, and valley fill at Soufrière Hills Volcano, Montserrat, from 1995 to 2013: Contributions from satellite radar measurements of topographic change
Frequent high-resolution measurements of topography at active volcanoes can provide important information for assessing the distribution and rate of emplacement of volcanic deposits and their influence on hazard. At dome-building volcanoes, monitoring techniques such as LiDAR and photogrammetry often provide a limited view of the area affected by the eruption. Here, we show the ability of satellitAuthorsD. W.
