Meeting: Fault2SHA 2019 workshop in Barcelona (Spain).
We presented an interpretation of the high-resolution seismic 3D seismic dataset in the offshore Southern California between Los Angeles and San Diego. The results show the presence of a complex fault system developed in a shear zone along the Newport-Inglewood Rose Canyon fault.

Meeting: Fault2SHA 2019 workshop in Barcelona (Spain).
We report evidence of left-lateral strike-slip displacement along the Al-Idrissi fault, characterize their fault segments and demonstrate that the fault was the source of the 2016 events.

Meeting: AGU 2018 Fall meeting in Washington DC (US).
We presented a preliminary interpretation of the high-resolution seismic 3D seismic dataser in the offshore along the Newport-Inglewood Rose Canyon fault, in the offshore Southern California between Los Angeles and San Diego.

Meeting: AGU 2018 Fall meeting in Washington DC (US).
Using state-of-the-art 3D geophysical tools, we have created high-resolution maps of structures along the Newport-Inglewood Rose Canyon fault. Using these maps we show examples of how fault segments tend to distribute strain and the crustal deformation that is created in the process. .

Meeting: RAUGM 2018 Annual Meeting in Puerto Vallarta (Mexico).
A study of the Coulomb stress transfer has been done to show the influence of the 1912 Acambay earthquake, produced in the Acambay fault in the Trans-Mexican Volcanic Belt, to understand the distribution of the regional seismicity after the earthquake and reveal the faults that accumulated stress due to this event and that could be close to rupture in a future event.

Meeting: SCEC 2018 Annual Meeting in Palm Springs (US).
To test different interpretations for the evolution and structure of the WTR, we used Trishear forward modelling. The Trishear models are a good first-order match to published geologic maps and well data. The modelling of multiple cross-sections argues that all of the observed deformation can be explained by an evolving fold and thrust belt, which includes a regionally extensive decollement underlying the observed thrusts and folds.

Meeting: ESC 2018 General Assembly in Valletta (Malta).
We report evidence of left-lateral strike-slip displacement in the Al-Idrissi fault, characterize their fault segments and demonstrate that this is a basement fault and the source of the 2016 earthquake events. Located along a lithospheric boundary, the Al-Idrissi Fault System is a young structure.

Meeting: Iberfault 2018 in Alicante (Spain).
We present an overview of the three largest continental strike-slip fault systems in the Alboran Basin: Carboneras, Yusuf and Al-Idrissi. Our dataset results from an integration of different types of acoustic and seismic data. This data is used to map and characterize better the active fault systems.

Meeting: EGU General Assembly 2018 in Vienna (Austria).
In this study, we estimate the total slip accommodated by the most prominent tectonic structures in the Alboran sea since the earliest Pliocene. Results show that estimated total slip accommodated by the main fault system may be similar (with error bounds) to the estimated plate convergence value since the Messinian time.

FAULT2SHA WORKSHOP

Earthquake ruptures can be accommodated in a complex manner by interaction among faults of very different characteristics and within a broad system, as it has been observed on recent large earthquakes (e.g. 2010 El Mayor Cucapah earthquake; 2016 Kaikoura earthquake). Modern seismic hazard assessment should thus be aimed at modeling fault-sources as an interacting system.
This 4th workshop of the Fault2SHA ESC Working Group was be devoted to complex-interacting earthquake fault systems, including discussion on available data (paleoseismological, geodetic, seismological, case histories) as well as on approaches for their modelling and integration into SHA. The meeting’s motto was “InterAction”. Not just because we wanted to debate about fault interaction as one of the main processes leading to complexity in active fault systems, but because we were looking forward to achieve effective communication between data providers, modelers and hazard analysts.
Program
The workshop consisted of three sessions, a roundtable and a debate session:
Session 1 – The EBSZ (SE Spain) lab: advances in earthquake geology research and seismic hazard modelling. The aim of this session was to analyze and discuss recent research work done specifically in the EBSZ and particularly on earthquake geology topics with implications in SHA, as well as seismic hazard models of the area.
Session 2 – Earthquake fault rupture and slip complexities: How-To OBSERVE them from field data. This session encompassed field research showing observations of complexity of earthquake fault systems: multi-fault ruptures, slip variations, ruptures on previously unknown faults, triggered ruptures, clustered and episodic behavior.
Session 3 – Earthquake fault rupture and slip complexities: How-To MODEL them in SHA. This session was devoted to research done on modelling multi-fault complex ruptures, as well as slip complexity, in fault hazard analysis.
