From 2016 to 2021, the INTAROS project examined monitoring gaps related to earthquakes and
other seismic events in the Arctic region and provided examples of how to close these monitoring gaps.
Stakeholders were engaged through the project, and policy briefs and information sheets were developed for
policy makers, regulators and the general public, giving recommendations on how to handle natural hazards
with a seismic signature. Earthquake data was collected using Ocean Bottom Seismometer (OBS) systems at
several locations in the North Atlantic, citizen based monitoring (CBM) was initiated in both Greenland and
Svalbard, and an earthquake bulletin and a station catalog were constructed for the region. The outcomes,
data, bulletin and catalog, are now available through the INTAROS iAOS (integrated Arctic Observing
System https://catalog-intaros.nersc.no/), including a bulletin web service providing various search options
and output options such as QuakeML and Nordic Format. In this presentation, we will provide information
on how to access the data and give examples using the data. The CBM units (Raspberryshake) were shipped
to local residents in Greenland, where they were deployed, providing important contributions to the seismic
monitoring of the region and new knowledge on the local ambient seismic noise levels. The CBM units in
Svalbard, were installed in public buildings with a high noise level, thus providing limited data on the seismic
monitoring in the region, but important information on the challenges in sensor installations in buildings
in permafrost areas.

The INTAROS project received funding from H2020 grant number 727890, see also
