EGU 2019 abstract deadline approaching

As every year just after the holidays, the abstract deadline for the EGU General Assembly in Vienna (April 7-12, 2019)  is approaching.  This year, it is on Thursday, 10 January 2019, 13:00 Central European Time.

This year, it seems that there is a strong focus on Earthquake Tectonics and Crustral Deformation (TS5) with 11(!) sessions focusing on this topic:

• Paleoseismicity, active faulting, surface deformation, and the implications on seismic hazard assessment (Fault2SHA) (co-organized) 
• Understanding fault growth and interaction over a range of spatial and temporal scales
• Integrated approaches to bridge Long-term Tectonics and Earthquake cycles: Observations, Experiments, and Models (co-organized)
• Earthquakes, active tectonics, and seismic hazard in regions of slow lithospheric deformation (co-organized)
• Crucial characteristics of earthquakes that generate tsunamis from geologic observations and numerical models (co-organized)
• Active Tectonics and Geodynamics of Anatolia
• Understanding large subduction earthquakes and tsunamigenesis by integrating geological and geophysical observations, laboratory results, and numerical modeling (co-organized)
• The Mechanics of Faulting from shallow to deep earthquakes: Interplay between multiple length scales. (co-organized)
• Earthquake foreshocks: identification, observation, modeling, and lessons to be learned (co-organized)
• Earthquake Source Processes: Recent Advances in Observation, Imaging, and Modeling (co-organized)
• Long-term evidence from past great earthquakes: critical observations and constraints for seismic hazard assessment (co-organized)

Each of them sounds exciting and worth contributing, so I am looking forward to a packed programm of earthquake tectonic – themed sessions!

However, if you cannot decide where to submit your abstract to, please consider our session on “Paleoseismicity, active faulting, surface deformation, and the implications on seismic hazard assessment” (TS5.1/GM4.5/NH4.16/SM3.10) at the following link:

Abstract

The study of active faults and deformation of the Earth’s surface has made, and continues to make, significant contributions to our understanding of earthquakes and the assessment of seismic related hazard.
Active faulting may form and deform the Earth’s surface so that records are documented in young sediments and in the landscape. Field studies of recent earthquake ruptures help not only constraining earthquake source parameters but also the identification of previously unknown active structures. The insights gleaned from recent earthquakes can be applied to study past earthquakes. Paleoseismology and related disciplines such as paleogeodesy and paleotsunami investigations still are the primary tools to establish earthquake records that are long enough to determine recurrence intervals and long-term deformation rates for active faults. Multidisciplinary data sets accumulated over the years have brought unprecedented constraints on the size and timing of past earthquakes, and allow deciphering shorter-term variations in fault slip rates or seismic activity rates, as well as the interaction of single faults within fault systems. Based on the this rich, but very heterogeneous knowledge of seismogenic faults, a variety of approaches have been developed to tranfer earthquake-fault geology into fault models suitable for probabilistic SHA. This session thus aims at linking field geologists, crustal deformation modellers, fault modellers, and seismic hazard practitioners.

In this session, we welcome contributions describing and critically discussing different approaches to study active faults. We are particularly interested in studies applying new and innovative methodological or multidisciplinary approaches. We hope to assemble a broad program bringing together studies dealing with on-land, lake or offshore environments, and applying a variety of methods such as traditional paleoseismic trenching, high-resolution coring, geophysical imaging, tectonic geomorphology, and remote sensing, as well as the application of earthquake geology in seismic hazard assessments. In addition, we encourage contributors describing how to translate fault data or catalogue data into fault models for SHA , and how to account for faults or catalogue issues.

We are looking forward to meeting you in Vienna,

best regards,
