Slow Slip in Costa Rica

Article

As more real-time GPS gets deployed, we are finding slow-slip events at lots of places. This first became well known around Vancouver, where they were finding frequent 'slow quakes'. These are fault slip events that happen too slowly to produce seismic waves. Nobody really knows what impact they have on real earthquakes, but it is assumed that they build up stress on the 'stuck' portion, until the 'Big One'.
