A Scripps Institution of Oceanography seminar scheduled for Oct. 21 focused on using small earthquakes to investigate how the central Andes deform. Sankha Subhra Mahanti, a postdoctoral scholar at Scripps' Institute of Geophysics and Planetary Physics, was the announced speaker. Seminar abstract.
The research described in the program combines reprocessed seismic records with machine-learning detection and dense instrument arrays. Those methods seek to reveal events that can be missed where seismic stations are widely spaced.
Small earthquakes can help researchers trace both deformation of the Earth's crust and movement associated with magma. The presentation was organized around three different tectonic settings in the central Andes, connecting detailed local observations with broader questions about mountain building.
The in-person session was listed for 2:30 to 3:30 p.m. in the Munk Conference Room. Research scope and schedule.
