The pre-meeting field trip of the 2026 PATA Days starts from Antigua Guatemala with 40+ people from 15 countries.
Three days of paleoseismology, archaeoseismology, and active faults ahead of us.

#patadays Day 3. Another spectacular evidence of Motagua fault, in a complex structural bending at La Laguna. Trastensive cinematic, well expressed in a paleoseismological trench.
