New Observations and Modeling of Triggered Seismicity
After a large earthquake occurs the seismic rate increases in its epicenter’s surroundings in the form of aftershocks. This is the most recognized form of triggered seismicity. However, many questions still remain open regarding the physics of aftershocks, including the aftershock’s maximum magnitude, their spatio-temporal distribution, the effects of fluid in the aftershock region and the role of the stress changes caused by previous mainshocks. Furthermore, observations show that other forms of seismicity can be also triggered, including slow-slip events, tectonic tremor, volcanic seismicity and icequakes. In addition, seismicity – both slow and fast – can be triggered dynamically thousands of kms from the source event.
 
In this session we invite contributions focused on new observations and the numerical or theoretical modeling of the different types of triggering of seismicity, in the near-field and the far-field (remote triggering). Understanding the different processes that can trigger seismicity, as well as the type of seismic events that can be triggered, is essential towards gaining a better understanding of the physics of earthquakes.
