Matt Loewen ’08 puts his Puget Sound education to work studying active volcanoes.

Matt Loewen ’08 studies the rocks he finds in some of the most remote corners of Alaska to help him understand volcanoes.

Loewen is a research geologist with the U.S. Geological Survey; he and his colleagues at the Alaska Volcano Observatory monitor dozens of active volcanoes across the country’s largest state. (Since records began to be kept in 1760, more than 50 volcanoes and volcanic fields have been active in Alaska.) Loewen’s field work—about four to six weeks each year—takes him from the observatory’s base in Anchorage to the western Aleutian Islands, some 1,500 miles away. The work can demand long days spent in less-than-luxurious lodgings.

For Loewen, it’s a dream job.

“I get to do incredible field work all the time,” he says. “In terms of experiences, this job is like a vacation. I get to go to unbelievably beautiful places that very few people get to go.”

Matt Loewen ’08 at Great Sitkin.

Loewen (shown here at Great Sitkin after its eruption in 2021) often collects samples just weeks after a volcano erupts.

When working at volcanic sites, such as a trip in 2019 following the eruption of Veniaminof—“The lava flow was still still quite warm”—Loewen studies the chemistry and the mineral composition of volcanic rocks. With each eruption, he says, “We try to understand why it did what it did, and you can look at rock composition to understand that.”

The most practical application of the work is to steer aircraft away from life-threatening volcanic ash clouds. “If we can prevent one aircraft encounter,” Loewen says, “that pays for what we do.”

Loewen credits the geology department at Puget Sound with launching his passion for volcanology. As an undergraduate working with Professor Jeff Tepper, Loewen studied volcanic activity that occurred 40 million years ago in northeast Washington.

"What I’m doing now,” he says, “isn’t all that fundamentally different from what I started doing as an undergrad."
