SeisMonitor in Colombia

We applied it to Colombia using nearly 7 years (2016–2022) of seismic data, successfully revealing significant tectonic structures and crustal faults.

Earthquake Detection & Phase Picking

We used EQTransformer to detect earthquakes and pick phases.

Mesetas Earthquake Detection

Phase Association

We used GaMMA to associate phases and obtained our first catalog.

GaMMA Catalog

NLloc Catalog

Although preliminary GaMMA locations are good enough to allow us to visualize the main seismic activity, we use NLLoc to further improve earthquake locations

Colombian Seismicity

It stands out for its computational efficiency, as well as its earthquake detection and location performance, demonstrating a high level of quality that effectively highlights key tectonic features and seismicity trends in northern South America.
