OVERVIEW:
I am a geophysicist whose research focuses on the earthquakes and sounds generated by volcanoes and landslides (and occasionally concerts). Many of the volcanoes I study are in the submarine environment, so my research often involves working at sea. I am always excited to hear from prospective graduate students, so if you enjoy math, physics, and geology, please reach out at caplanj@wwu.edu.
RECENT NEWS:
Honored to have participated in this study led by Dr. Dan Shugar at the University of Calgary. Our paper, recently published in Science, describes a multidisciplinary approach to studying the second-largest landslide tsunami ever recorded. The August 2025 Tracy Arm landslide generated a wave that sloshed across the fjord to heights exceeding 480 m (that's 2.5 Space Needles for you Pacific NW types). In our paper we describe the seismic signals that preceded and followed the event, and propose that events like this are likely to occur more frequently as human-induced climate change causes more glaciers to thin and retreat.
