than 30,000 earthquakes at 5–7 km depth, advancing in short bursts at 0.3–4.7 km/h. Following each
surge forward, the seismicity behind the dyke tip dropped, implying that the subsequent dyke opening
was mostly aseismic. More detailed analyses of the seismic data recorded by a dense network around
the Vatnajökull icecap have revealed small magnitude, long-period (LP or B-type) events which
