For example, how earthquakes start and grow, what factors govern the size and location of slip, how one earthquake affects another. I have studied earthquakes over a wide range of magnitudes and frequencies in many tectonic environments. I worked in the Aegean, Southern California and New Zealand before coming to Boston. In particular I have focused on earthquake scaling and nucleation. I have also worked on attenuation and site effects. My aim is to understand the factors controlling seismic slip by studying earthquakes under a wide range of conditions (for example, on the San Andreas System, in subduction zones, and in the oceans). I am also using the relatively controlled environment of induced seismicity to understand the triggering of tectonic earthquakes.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>Since 2021, with <a href=\"https:\/\/www.usgs.gov\/staff-profiles\/annemarie-baltay\">Annemarie Baltay (USGS)<\/a> I have been leading a community collaboration to improve estimates of earthquake source parameters, focusing initially on spectral stress drop. The work is sponsored primarily by the <a href=\"https:\/\/www.scec.org\/events\/2025-scec-stress-drop-workshop\/\">USGS and SCEC<\/a>, and is ongoing.
