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
floods.Jökulhlaups cause by melting due to hot pyroclastic flow

Amplitude Measurement (RSAM) data are one of the most
important tools utilized in volcano observatories worldwide. The IMO’s monitoring office is
no exception, as this type of real-time data shows mid- to long-term trends, which is especially
important for monitoring active volcanic systems. The RSAM methodology was developed by
the USGS in 1989 (Murray & Endo, 1989) to plot averaged amplitude

The 1994 swarm began on 11 May and lasted until 27 June. Between 120 and 130
earthquakes were located during that period, mostly beneath the northern flank of the
volcano. Dahm and Brandsdóttir (1997) analyzed 15 selected earthquakes from the 1994
swarm which were also recorded on a temporary network. Lacking a velocity model for

The hazards associated with each volcano are related to the type, location and intensity of an eruption. Public vulnerability to volcanic hazards increases as the number of people exposed to the hazard grows. A key issue in mitigating volcanic risk is the capability to detect, interpret, and communicate volcanic signals before and during a volcanic eruption.

vent. The type and style of the eruption also affect the
plume altitude as well as the size of the erupted material. Pyroclastic
material in the plume is subjected to two main forces: the force of gravity and
the drag of the rising gas stream. Small pyroclastic material will then be
transported to the top of the plume, whereas larger particles will lose
momentum quicker and will abandon
