John Lyons
I study infrasound and seismic data from restless and erupting volcanoes in Alaska and around the world. Analyzing geophysical data from volcanoes helps me better understand the processes that generate the signals and informs the hazards associated with those processes. My research also aims to identify and develop better tools for monitoring changing and potentially hazardous eruptive activity.

Science and Products
Magmatic degassing, lava dome extrusion, and explosions from Mount Cleveland volcano, Alaska, 2011–2015: Insight into the continuous nature of volcanic activity over multi-year timescales
Seismic envelope-based detection and location of ground-coupled airwaves from volcanoes in Alaska
Long period seismicity and very long period infrasound driven by shallow magmatic degassing at Mount Pagan, Mariana Islands
Long period (LP) seismicity and very long period infrasound (iVLP) were recorded during continuous degassing from Mount Pagan, Mariana Islands, in July 2013 to January 2014. The frequency content of the LP and iVLP events and delay times between the two arrivals were remarkably stable and indicate nearly co-located sources. Using phase-weighted stacking over similar events to dampen noise, we find
