Five samples from an overlying peat and underlying silt and mud layers within the most recent surface rupture at the Burro Flats Trench Site northeast of the town of Banning in Southern California were submitted for pollen analysis. The analysis was performed in order to determine whether the rupture can be associated with the 1812 Wrightwood earthquake or the Coachella Valley earthquake, circa 1700.
