A new coordinated project, composed by three subprojects led by fault2sha members of the Eastern Betics fautl2SHA-lab has been funded by the Spanish Ministry of Science and Innovation (PID2021-124155NB-C31).
Project Title: SHaKER, Seismic Hazard Knowledge for Earthquake Resilience
IPs: José A. Álvarez Gómez, José J. Martínez Díaz (UCM, subproject model_SHaKER), Carolina Canora (UAM, subproject paleo_SHaKER) and Alejandra Staller (UPM, subproject Geo_SHaKER)
The main objective of the SHaKER project is to advance in the knowledge of the seismogenic processes of seismic sources with the final objective of improving urban resilience to seismic disasters. To achieve this, we delve into the characterization of seismogenic source models with the integration and correlation of a number of disciplines in an interdisciplinar and multidisciplinar approach. To characterize the seismic sources we will use geological, geochemical, geotechnical, geodetic and geophysical data in addition to the development of numerical modelling and data analyses through machine-learning techniques. The numerical modelling will allow us to get insight into the complex, nonlinear, relations between the faults of the system, but also including external geological processes and tectonics in the long term evolution of fault systems.
These seismic source models are the basis for the development of new seismic and tsunami hazard and risk assessment studies, whose results will be essential to establish new proposals for improving urban resilience. The SHaKER project will help to estimate the faults seismic cycle and transient behaviours and characterize those seismogenic sources, including their kinematics and mechanical properties. These data will help us to quantitatively assess the sensitivity to uncertainties, thus contributing to reach the UN SDG11 in terms of the improved assessment of seismic risk, making the cities more inclusive, safe, resilient, and sustainable. In concordance with this aim we will develop also better assessments of earthquake triggered slope instabilities, earthquake surface ruptures and liquefaction.
We will continue the studies carried out in previous projects in two seismically active and densely populated zones, with different tectonic behaviours and transcurrent faults of special interest: the Eastern Betic Shear Zone (EBSZ) and the El Salvador Fault Zone (ESFZ). The EBSZ is one of the areas with the highest seismicity in the Iberian Peninsula where the largest populations (Lorca, Totana, Alhama de Murcia) are located directly above the fault traces. The need for a detailed study of the behaviour and geological history of these faults became evident after the 2011 Lorca earthquake, moderate magnitude event that caused important damage. The ESFZ is a system of strike-slip faults with significant seismic activity and a medium to high deformation rate, aligned within the volcanic arc, where a large part of the country’s population is concentrated. In this case, we will try to improve the knowledge of the ESFZ in the less studied areas, expanding our study to the Nicaraguan and Guatemalan volcanic arcs (including the Jalpatagua fault).
The SHaKER project will be backed by a multidisciplinary research team made up of geologists, geochemists, geophysicists, mathematicians, civil engineers and geomatics engineers. This guarantees the integration and correlation of diverse data sources, as well as the establishment of different approaches to assess the seismic hazard and its relationship and influence on the seismic risk and future urban planning. The results of the project will help to reinforce the resilience of cities in terms of seismic risk, generating products and tools that will be useful for public institutions and decision-makers, who work in emergency planning before de disaster.

The Fault2SHA Ex-Com would like to
welcome José Antonio Álvarez Gómez as a new member. His broad interests in many of the topics discussed within Fault2SHA will certainly enhance the link between fault data provider and fault data modelers.
thank Julián García-Mayordomo who has decided to leave the Ex-Com. Julian has been an active member of the Fault2sha Ex-Com since the creation of the Working Group. He will remain a very active member of the working group, in particular with our Colombian collegues. We wish him all the best for the future.
We are excited to announce that a new project based on the Fault2SHA approach has been funded, led by two of the fault2sha members and involving mostly researchers of the Eastern Betics fautl2SHA-lab (but not only!).

Project Title: NSOURCES: New approaches to earthquake source characterization and their effective integration into fault-based seismic hazard models. Case studies in areas of low-to-intermediate activity of eastern Iberia
IPs: Raimon Pallàs and Eulàlia Masana (Univ. of Barcelona)
Main Partners: From Spain: Universidad Complutense de Madrid; IGME; Universidad Autónoma de Madrid; Centro Tecnológico del Mármol, Piedra y Materiales; ICGC; Centro Nacional de Investigación en Evolución Humana (CENIEH); SOLDATA IBERIA S.A.; Abroad: IRSN and Univ. of Montpellier (France); Univ. degli Studi G. d’Annunzio-Chieti-Pescara (Italy), UNAM (Mexico); San Diego State University (USA), Helmholtz Institute (Germany); Univ. of Manchester (UK)
The Eastern part of the Iberian Peninsula is one of the most seismically active areas in Europe. Although at a smaller rate compared with other active settings, highly damaging earthquakes also occur in Western Europe, where large uncertainties in seismic hazard combine with low societal awareness to result in increased seismic risk. In Eastern Iberia, some of the seismogenic sources remain poorly studied. This is often due to the subtle expression of active slow faults, especially those located in highly erosive environments or not associated to large nor active fluvial drainages.
In this project, seismic hazard assessment of Eastern Iberia aims to be improved by incorporating new and more precise data on the source seismic parameters of three study areas; the Eastern Betic Shear Zone (EBSZ), High Pyrenees (HP) and the Baix Ebre basin (BEB). The main targets are the Maladeta-Bedous fault system (in the HP), the Palomares fault (in the EBSZ) and the Baix Ebre fault (in the BEB), among others. The improved characterization of their seismic parameters will be achieved with a paleoseismological approach enhanced with new tools in geochronology, geodesy and geophysics, that include i) accurate fault slip-transects and refined fault mapping using LiDAR data, photogrammetry and field work; ii) combination of chronological tools as Schmid hammer, cosmogenic isotopes and violet stimulated luminescence that will sum up with more classical methods; iii) refined location of the paleoseismic event horizons with the use of hyperspectral images; iv) obtention of new geodetic (GPS and CGPS) and InSAR data; v) geophysical characterization of the fault geometry by a joint interpretation approach (Reflection Seismics, Magnetotellurics, Electrical Tomography and GPR).
As a final aim, all the new information on source parameters will serve to perform new probabilistic seismic hazard calculations (fault-system approach in the EBSZ and single-faults in the HP and BEB). Along with this new fault-based PSHA results, educational and information strategies will be undertaken to increase the local population awareness on seismic hazard. The project will make possible the training of young researchers with the implementation and testing of new tools on active tectonics as well as fault-based seismic hazard analysis.
The workshop in Pisa (IT) “Hands-on fault-based PSHA: data and approaches to build models” is over. For many of us it was the first in-presence meeting after a long period of restrictions due to COVID-19.We hope it could represent the first of many other opportunities, for this enlarged community! We thank all the speakers, participants, INGV and Italian Civil Protection Department for the chance given both of discussing scientific topics and sharing technical issues. The Fault2SHA EXCOM believes it is time to think and organise the 6th Fault2SHA meeting, isn’t it? You will be asked soon to choose about two options that seems to be feasible for next Spring, in 2022. Your vote will drive the choice, then ……..stay tuned!
We would like to invite you to submit an abstract to the session “S14: Imaging and modeling 3D fault complexities in FAULT2SHA” at the 37th General Assembly of the European Seismological Commission.The ESC will be held virtually on 19-24 September 2021. (https://www.erasmus.gr/microsites/1193). The deadline for the abstracts submission is on April 19, 2021.
S14: Imaging and modeling 3D fault complexities in FAULT2SHADefining the 3D geometries of faults and their structural and rheological complexities not only presents challenges for field geologists, but also for seismic hazard assessment (SHA). Roughness of the fault plane, friction, asperities and bends constitute primary controlling parameters in physics based earthquake rupture models. Advanced seismic-cycle and earthquake rupture simulations incorporating these variables in 3D models have shown the occurrence of complex earthquake ruptures. Meanwhile, structural and field geologists are analyzing data at micro- and macro-scales, revealing that microscale observables can influence earthquake ruptures, or that, for example, strain partitioning, propagation of earthquake rupture or the seismic/creeping behavior can be influenced by steps, bends, gaps and barriers within and between faults. Modeling the 3D geometry incorporating the variability of these fault parameters along-strike and down-dip is the new frontier that earthquake scientists are beginning to explore, and a key scientific target of the Fault2SHA community. Finally, as the assessment of seismic hazard is ultimately concerned with the expected ground motion, to what extent are empirical ground motion prediction equations and physics-based ground motion simulations capable of capturing these complexities? This session welcomes contributions from: (i) earthquake geologists, seismologists and structural geologists exploring fault geometry and behavior, including detailed imaging of fault properties along-strike and down-dip; (ii) simulations of complex ruptures and earthquake recurrence through dynamic and multi-cycle simulations; (iii) incorporation of characteristic of 3D fault based ruptures into SHA; (iv) and ground motion modelers (empirical and physics-based) investigating the influence of such complex micro- and macroscale 3D complexities.
