A web service providing parametric data from cryo-generated seismic events in Greenland

We here present a web service that provides parametric data from cryo-generated seismic events in Greenland, detected, processed and analysed at the Geological Survey of Denmark and Greenland – GEUS. The web service consists of two web listings, one with a simple CSV listing of time and location and one including all the parametric data of the cryo-generated events, e.g. location uncertainties and arrival times and amplitudes of the seismic waves at the seismic stations. Here we outline the background for seismic monitoring of sources related to the dynamics of the cryosphere, the observation of glacial earthquakes, and the initiation of the ongoing GLISN project. We describe the process of extracting the parametric data from the seismic recordings in Greenland for the database that is linked to the web service. We describe how to access and use the web service. The nature of seismic signals from the cryo-generated events, provided by the web service, are often tremor signals with unclear or multiple P- and S- phases, the uncertainty of the location of the events is therefore also addressed.
