Figure 3. Epicenters (Ml > 1.7) beneath the Mýrdalsjökull glacier and the cumulative number of Ml > 1.7
earthquakes and strain release west of Goðabunga (western Mýrdalsjökull) from 1999 to 2002. This magnitude
range represents a relevant comparison of the seismicity, since the detection level has been lowered during the
last years. Triangles denote SIL seismic stations. Below, earthquake magnitude versus time for the same period.
