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

hail, lightning and dust storms. There is no clear trend in the annual
numbers of tropical cyclones. {WGI 3.2, 3.8, 4.4, 5.3, SPM}

SISZ, three and a half days and approximately 17 km apart. Seismicity greatly increased in
all Southwest Iceland and during 2000, roughly nineteen thousand microearthquakes were
recorded there. The aim of this research is to relocate the earthquakes using a double-

) is monitoring the region.
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.
