Earthquake Summary Posters - 2026

small example of poster — Small example of an earthquake summary poster.

Each poster in the Earthquake Summary Poster series contains multiple panels showing the epicentral area, plate tectonic environment, earthquake history, and generalized seismic hazard of the region. These posters are approximately 36x24 inches (width x height).

The posters should be considered preliminary. They are neither completely definitive (the earthquake data are those available in the first few days after the event) nor totally accurate (the map base may contain obsolete information, for example).
