Dear colleagues,
EGU abstract submission deadline is getting closer, and we would like to invite you to submit an abstract to the session: Earthquake processes in volcanic environments (SM6.1/GD3.5/
Invited speakers:
Christopher Bean (Dublin Institute for Advanced Studies),
Michelle Parks (University of Iceland).
We encourage all contributions focusing on seismic signals recorded on volcanoes (either from the earthquake or volcano seismology).
Hope to see you in Vienna,
Vala, Stína, Halldór, Ivan, Ozgun
______________________________
Please be aware about the below dates for the EGU General Assembly, Vienna | Austria | 23–28 April 2017.
Abstract submission deadline: 11 Jan 2017
Note that Vienna will be extremely busy just before and during EGU because of the Vienna Marathon (on April 23) and another conference at the same time as EGU. Please make your bookings way in advance (i.e. as soon as possible).

Earthquake processes in volcanic environment
Convener: Vala Hjörleifsdóttir, Kristín Jónsdóttir, Halldór Geirsson , Ivan Lokmer , Ali Ozgun Konca
Abstract submission Seismicity at volcanoes is fundamental for monitoring and understanding volcanic systems, their structure and the processes that occur therein. A diverse range of volcanic processes produce measurable elastic waves, including magma intrusions and dike propagation, caldera deformation, faulting, landslides, explosive activity, fluid flow and more. Earthquakes in volcanic environments are often anomalous, resulting in unusual source mechanisms which challenge interpretation and common methods of analysis. In addition, seismic catalogues from volcanic settings tend to deviate from those collected in tectonic environments, raising questions about our understanding of earthquake processes and the effect the different environments have on various catalogue data distributions.
Recent studies in volcano seismology pose interesting questions, on e.g. the source mechanisms of the caldera collapse related Bárdarbunga earthquakes and the origin of repeating small tremor-like earthquakes that occur at unusual depths, many km below were most brittle earthquakes occur. Another example of the seismicity under debate are LP events, for which recent studies suggest that may be linked to slow slip faulting in the weak uppermost part of the volcano.
This session aims to bring together a range of Earth Scientists, who employ different techniques, within the field of seismology and high-rate deformation studies, based on GPS-, strain-, accelerometer- and/or tilt-data to study earthquake processes that occur in volcanic settings. We welcome contributions assessing the study of earthquake source mechanism, seismic tremor as well as the study of earthquake catalogues where the aim is to reveal the underlying processes that take place in volcanic environments.
