Please consider submitting an abstract to session TS5.4/NH4.8/SM6.6
“Advances in understanding earthquake processes and hazards in regions of
slow lithospheric deformation (co-organized)” at the EGU General Assembly
in Vienna, Austria (April 23-28, 2017).
Dan Clark (Geoscience Australia) has accepted an invitation to give a
solicited presentation in this session, with a focus on recent advances in
understanding seismogenic intraplate deformation in Australia.
– Session Description –
Earthquakes that occur within regions of slow lithospheric deformation (low
strain regions) are inherently difficult to study. The long interval
between earthquakes coupled with natural and anthropogenic modification
limit preservation of such events in the landscape. Low deformation rates
push the limits of modern geodetic observation techniques. The short
instrumental record challenges extrapolation of small earthquake recurrence
based on modern seismological measurement to characterize the probability
of larger, more damaging earthquakes. Characterizing the earthquake cycle
in low-strain settings is further compounded by temporal clustering of
earthquakes, punctuated by long periods of quiescence (e.g. non-steady
recurrence intervals). However, earthquakes in slowly deforming regions can
reach very high magnitudes and pose significant risk to populations.
This session seeks to integrate paleoseismic, geomorphic, geodetic,
geophysical, and seismologic datasets to provide a comprehensive
understanding of the earthquake cycle. This session will draw upon recent
advances in high-resolution topography, geochronology, satellite geodesy
techniques, subsurface imaging techniques, longer seismological records and
other high-density geophysical networks and unprecedented computational
power to explore the driving mechanisms for earthquakes in low-strain
settings. We welcome contributions that (1) present new observations that
place constraints on earthquake occurrence in low-strain regions, (2)
explore patterns of stable or temporally varying earthquake recurrence, and
(3) provide insight into the mechanisms that control intraplate earthquakes
via observation and/or modeling.
