## Resource

On Union College Week: How do we unravel the secrets of volcanoes? Holli Frey , professor of geosciences, examines tiny crystals to gather clues. Faculty Bio: Holli Frey is a professor of Geosciences from Union College (NY). She studies volcanoes, trying to understand the plumbing systems beneath them, looking for clues as to how and why they erupt. She is particularly interested in mineral chemistry and chronology and uses a variety of analytical tools to address fundamental questions about magma evolution. She has active field-based projects in the Caribbean (St. Vincent and Dominica) and Central Oregon (Tumalo Tuff) and previously did work in the western Trans-Mexican Volcanic Belt and plutons in coastal Maine. She enjoys mentoring students, who are frequently co-authors on her publications. Her most recent work is on the eruptions of St. Vincent and she is a project partner of Dr. Jenni Barclay (University of Bristol) on a funded, collaborative grant, “Ex-X: Expecting the Unexpected (Understanding Dangerous Volcanic Transitions)”. This summer, Dr. Frey will take several students to Dominica, continuing to explore the eruptive history of the island. Dr. Frey received her B.A. in geology from Franklin and Marshall College and her PhD in geosciences from University of Michigan, supported by a National Science Foundation Graduate Research Fellowship. Transcript: In early 2021, the volcano La Soufrière in St. Vincent in the Caribbean rumbled to life after more than 40 years. Thick lava slowly oozed out at the summit, not a real threat to the 16,000 people living in its shadow. Then, in April, everything changed. The shaking beneath the volcano shifted, prompting an evacuation. In less than 24 hours, powerful explosions began, sending ash high into the atmosphere. For tw…
