I’m from one of the most active subduction zones in the world, and I love earthquakes and landforms created by tectonic activity. I’m a Chilean Geologist living in Seattle, and I moved to the US to start my Ph.D. at the University of Washington (UW) in Fall 2020. I’m part of two research groups at UW: tectonic geomorphology and geodesy, and now I’m studying the landscape evolution of strike-slip faults in hyper-arid environments in Northern Chile. I’m trying to measure slip rates of these crustal structures using short-term data (GPS) and long-term records (geomorphology); test predictions of strike-slip models; understand the relationship between short and long-term deformation, and assess their seismic hazard. I found this project thanks to an email in my seismology class and I immediately started looking for information about it to apply as a volunteer. Knowing more about Cascadia is one of my goals during my Ph.D. I think that comparison is a great learning method for science and I want to apply my knowledge from Chile to Cascadia and about Cascadia to Chile when I get back there. There are so many things in common in these two areas! During fieldwork, my favorite part was driving through the macromorphologies: crossing from the valley at the east side, to the Coastal Range in the middle, and towards the west getting to the Coast. I enjoyed the great views at high altitudes that give you a big panoramic of the multiple geologic processes that had to happen to see the actual landscape of Oregon.
