Large sections of land on either side of the San Andreas fault are moving up or down every year by a few millimeters, a major form of motion that researchers report in a new study that sheds light on the mechanics of the famous fault line.
Compared to the more predictable horizontal movement of the fault in between earthquakes, the vertical motion of the land on either side of the fault has been more mysterious, according to the study. The pattern the researchers found was hard to detect in the messy data, which came from an array of GPS sensors, so the scientists used a statistical method to make sense of it.
The up and down motion occurred in patches of land so big— about 125 miles wide— they can be described on the county level. Santa Barbara County, San Luis Obispo County, and a big section of San Bernardino County are rising at a few millimeters per year, The Los Angeles Times reported, while Orange County, San Diego County, and a large part of the Los Angeles Basin are sinking.
