Michelle Lynn Coombs is a geologist at the Alaska Volcano Observatory (AVO). She was the Scientist-in-Charge from 2016 to 2023.^[1][2] Coombs is a fellow of the Geological Society of America.^[3]

• 1994: B.A. Geology (Williams College)
• 2001: Ph.D. Geology (University of Alaska Fairbanks)^[4]

Coombs is married to USGS geologist Evan Thoms.^[5][6]

Michelle is originally from Maine,^[7] where Coombs is a common last name.^[8][9]

Coombs was the Scientist-in-Charge (SIC) of AVO from 2016 to 2023.^[10] As the SIC, she was in charge of coordinating emergency responses to volcanic eruptions, and guides the process of monitoring volcanic activity in Alaska.^[11] She is frequently quoted in the news as a subject-matter expert on volcanoes in and around Alaska.^[12] As the SIC, she was also the main contact from the media to AVO. Dr. Matthew Haney became the new SIC of AVO in August 2023, succeeding Coombs.^[13][14]

She is the second woman in AVO history to serve as the Alaskan SIC, as Terry Keith held the position from 1994–99.^[15] When she became SIC in 2016, she was one of 3 women serving as a Scientist-in-Charge of a USGS-operated Volcano Observatory, but as of March 2023, she was the only one.^[16]

She has worked with the AVO since 2004, before which she worked for the USGS's Volcano Hazards Program out of Menlo Park, California;^[16][17] which she joined after completing her Ph.D.^[7]

While Coombs was in college, she was a field assistant to Judy Fierstein. Once she began working at AVO, she became a mentee of Terry Keith and Tina Neal.^[16]

Coombs was the advisor to a 2011 internship studying the 2006 eruption of Augustine Volcano.^[18] She had previously co-edited a 2010 U.S. Geological Survey Professional Paper on the eruption.^[19]

Coombs has also been a participant of a volcanic eruptions workshop from the National Academies.^[20]

Coomb's main research focus is volcanology.^[21] Much of her research is on volcanic geology in Alaska, but she has also published research on volcanoes in Hawaii,^[22] and her doctoral dissertation was on Mount Desert Island, Maine.^[23]

Coombs is an expert on the geology of the Aleutian Arc, having published extensively on it.^[24]

In 2019, Coombs and a group of collaborators were awarded a NSF grant to model eruptions of Alaskan volcanoes.^[25]

As well as currently being a fellow to the Geological Society of America (GSA), she stood on the Student Awards Committee for the American Geophysical Union (AGU) from 2011–2015.^[26]

Coombs was an Associate Editor for the Bulletin of Volcanology (2013–2016), and was on the editorial board of Journal of Volcanology and Geothermal Research (2007–2018).^[24] She has also served as a Steering Committee member for the Community Network for Volcanic Eruption Response (CONVERSE).^[27]
