Michelle Coombs

Michelle Coombs is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Michelle Coombs rather than just read about it. In short: Michelle Lynn Coombs is a geologist at the Alaska Volcano Observatory (AVO). She was the Scientist-in-Charge from 2016 to 2023.

Key takeaways

Michelle Coombs belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Michelle Coombs to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Michelle Coombs from memory before moving on to harder problems.

Reference excerpt

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

Education 1994: B.A. Geology (Williams College) 2001: Ph.D. Geology (University of Alaska Fairbanks)

Personal life Coombs is married to USGS geologist Evan Thoms. Michelle is originally from Maine, where Coombs is a common last name.

Career Coombs was the Scientist-in-Charge (SIC) of AVO from 2016 to 2023. As the SIC, she was in charge of coordinating emergency responses to volcanic eruptions, and guides the process of monitoring volcanic activity in Alaska. She is frequently quoted in the news as a subject-matter expert on volcanoes in and around Alaska. 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. She is the second woman in AVO history to serve as the Alaskan SIC, as Terry Keith held the position from 1994–99. 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. She has worked with the AVO since 2004, before which she worked for the USGS's Volcano Hazards Program out of Menlo Park, California; which she joined after completing her Ph.D. 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. Coombs was the advisor to a 2011 internship studying the 2006 eruption of Augustine Volcano. She had previously co-edited a 2010 U.S. Geological Survey Professional Paper on the eruption. Coombs has also been a participant of a volcanic eruptions workshop from the National Academies.

Research Coomb's main research focus is volcanology. Much of her research is on volcanic geology in Alaska, but she has also published research on volcanoes in Hawaii, and her doctoral dissertation was on Mount Desert Island, Maine. Coombs is an expert on the geology of the Aleutian Arc, having published extensively on it. In 2019, Coombs and a group of collaborators were awarded a NSF grant to model eruptions of Alaskan volcanoes.

Affiliations 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. 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). She has also served as a Steering Committee member for the Community Network for Volcanic Eruption Response (CONVERSE).

Worked examples

Example 1 — a first encounter with Michelle Coombs

Start with the simplest possible case. Write down what Michelle Coombs claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Michelle Coombs before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Michelle Coombs ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Michelle Coombs

In research: Michelle Coombs appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Michelle Coombs in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Michelle Coombs is common in secondary-school and first-year university syllabi. It links to neighbouring topics American volcanologists, American women geologists, Fellows of the Geological Society of America, so understanding it makes those chapters shorter.
In everyday life: Look for Michelle Coombs outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
