It is the subduction of the Pacific Plate under the Okhotsk microplate (belonging to the large North America Plate) which drives the volcanic and seismic hazard in this remote area. The surface expression of the subduction zone is the 2100 km long Kuril-Kamchatka volcanic arc: a chain of volcanic isla ...[Read More]

GeoTalk: The mantle and models and measurements, oh my! Talking geophysics with Juan Carlos Afonso

This week in GeoTalk, we’re talking to Juan Carlos Afonso, a geophysicist from Macquarie University, Sydney. He explains how a holistic approach is crucial to understanding tectonic processes and how a little “LitMod philosophy” can go a long way to achieving this… First, could you introduce yourself and tell us a little about what you are currently working on? My name is Juan Carlos Afonso and I’ ...[Read More]
