IGCP Project 641 (Mechanisms, Monitoring and Modeling Earth
Fissure generation and Fault activation due to subsurface Fluid
exploitation - M3EF3) held its second international workshop from
November 2 to 6, 2016, in Puerto Vallarta and included a two-day
field trip to Guadalajara and Jocotepec in the Mexican state of Jalisco.
M3EF3 is aimed at i) understanding the mechanisms that
cause the formation of "ground ruptures", as a response to changes in
the stress state in the subsoil, ii) monitoring their occurrence, and iii)
developing appropriate approaches to model their formation and growth.
Located in the Tran Mexican Volcanic Belt, a
major volcanic E-W structure in central Mexico, Jocotepec is a city
with approximately 40,000 inhabitants on the westernmost shore of
Lake Chapala, at an elevation of about 1,540 m above mean
sea level. Here, ground rupture associated with land subsidence due to
groundwater withdrawal and regional faulting is the main geologic
hazard.
