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.

#patadays Day 2. The rupture of 1976 eq. on the Motagua fault, and his offset along a canal

#patadays in Guatemala. Day 1 of the pre-congress field trip. Paleoseismological trench of 1976 left lateral strike slip of Motagua fault.

If you were far away from the Earth, on a line that intersects the centers of the Sun and the Earth, here's the sunlit half of the Earth you would be seeing during the June and December solstices. Two very different views of Earth! 🧪
