DOI: 10.1007/s00445-021-01442-7
Abstract: Understanding interactions between tectonic faults and a nearby active volcano is often realized by combining seismic and field observations. A good example of such an interaction is the Caviahue caldera. It is located in an… read more here.

DOI: 10.1016/j.jvolgeores.2021.107321
Abstract: Abstract Deep low-frequency earthquakes (DLFs) beneath volcanoes are possible evidence for deep-seated magmatic activity in the mid-to-lower crust and uppermost mantle. After the 2011 Tohoku-oki earthquake (Mw 9.0), the number of DLFs beneath the Zao… read more here.

DOI: 10.1785/0220200429
Abstract: We examine earthquake hypocenters, focal mechanisms, and the state of tectonic stress in the Lower St. Lawrence Seismic Zone (LSZ), a paleorift zone in eastern Canada. The largest earthquake recorded in the region is the… read more here.
