volcanic tremor.
The main objective of this project was to develop a new open source python- and RSAM-based
early warning software that provides an audio alarm for the onset of volcanic eruptions, by
using known signatures of seismic eruption tremor signals. The new module Tremv-ALERT,

(cGPS) data recoded on Heimaey since 2000 until November 2018 shows no significant de-
formation signals related to magmatic movements. Periodic analyses of gases released at Eldfell
and Surtsey show that the gases contain primarily steam (water) with little magmatic signature.
