What this page is. The station's automated detector flagged a burst of ground motion at this time, and matching it against the USGS ANSS catalog identified it as this earthquake. Magnitude and location are USGS's — a single home station cannot compute them. The one thing measured here is how hard the ground in Soquel moved.
