Right after a large magnitude earthquake occurs, some areas near its epicenter experience an increase in seismic activity. Furthermore, increases in seismicity have also been observed in places very distant from large earthquakes the moments after they occur. This phenomenon is known as dynamical or remote triggering of seismicity. This is explained as the result of physical changes caused by the passing of the seismic waves (from the large earthquakes) that bring faults closer to failure. In this work, we present new observations of dynamic triggering of earthquakes and tectonic tremor in Mexico and the USA caused by the Mw=8.1, 2017 Chiapas (Tehuantepec) Mexico Earthquake.

Key Words
