We've only been running software for continuous sudden motion sensor monitoring
software on a single Mac laptop for a few months. Unfortunately, our initial
software was not stable, so we had many significant gaps in data coverage that
unluckily happen to correspond to several regional earthquakes. The first earthquake we
recorded with our preliminary software was an ml 3.7 event on August 8th,
2007.
This figure shows (blue) the significance level and (red) the vertical
component.
