active system in Iceland. The activity has changed in terms of frequency and type of eruptions with time. The period 9000-7000 years ago was dominated by effusive basaltic volcanism, the period 7000-3000 years ago was characterized by infrequent but large explosive silicic eruptions at the central volcano, and the last 3000 years have been dominated by more frequent and smaller mixed silicic

Usually the transport time is shorter, but if the slope gradient

away from the eruption site, but it can also accumulate around the site. Increased accumulation leads to the reservoir becoming unstable and the release of a jökulhlaup. Jökulhlaups from Eyjafjallajökull in 2010 are an example of this type of flood. In large eruptions, such as Katla eruptions underneath Mýrdalsjökull, ice melting can be very rapid and substantial in volume, resulting in large

"There's tremendous change all around us," says Matthew J. Roberts, glaciologist at the Icelandic Meteorological Office, in an interview taken on Solheimajokull. "This is a type-site for glacial retreat in Iceland and, in fact, globally."
Sólheimajökull is one of several valley glaciers extending

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
