Slow Slip and Tremor Detected at the Northern Costa Rica Seismogenic Zone

Figure: Tremor locations (small green dots) between May 17 and June 4, 2007. The box indicates the horizontal projection of the fault plane assumed in inversion of the GPS data for slip during the May 2007 slow slip event. The red circle estimates the location of maximum slip (up to 9 cm) during this event. Red squares represent the location of deep and surface seismic sites and large green dots borehole seismic stations. S. Schwartz1, J. Walter1, T. Dixon2, K. Psencik2, J. Protti3, V. Gonzalez3, M.
