Dear colleagues,

We would like to remind the community of the upcoming session on *Earthquake
Dynamics and Interactions* at the 4th Regional Assembly of the Latin
American and Caribbean Seismological Commission (*LACSC*), to be held this
year *October 3-5, in Quito*, Ecuador. The deadline for submitting
abstracts* has
been extended to Monday 18 of July*. Please consider submitting an
abstract to our session at the following link:

*LACSC-7 - Earthquake Dynamics and Interactions*
A variety of mechanisms have been invoked to explain the underlying physics
driving earthquake nucleation and slip, including co-seismic static and
dynamic stress changes, aseismic deformation, fluid-driven processes caused
by underground injection of fluids, and other general fluctuations in
background stress states. What is less certain is how or if this wide range
of processes may be linked on multiple spatial and temporal scales, and by
studying these interactions, reveal a fundamental earthquake rupture
process. In this session, we seek studies ranging from the theoretical to
the observational that may address: (1) To what extent can the potential
for static and dynamic triggering be differentiated, and is that difference
relevant? (2) What are the mechanisms and time scales by which medium
changes (changes in damage profile, permeability/porosity, or seismic
velocity) operate on and modulate background seismicity? (3) What changes
in stress conditions stored on ancient faults are needed to trigger an
earthquake from external perturbations (i.e., fluid injection), and could
all faults reactivate with local stress changes? (4) What are the
frictional conditions that govern the final size of an earthquake and can
these conditions be observationally gleaned beforehand? and (5) Are there
paradigmatic or computational blind spots that must be addressed before
progress can be made in these areas?
