Western Mediterranean Seismicity
Research Guide

What is Western Mediterranean Seismicity?

Western Mediterranean Seismicity studies earthquake distribution, stress regimes, and active fault systems along the Azores-Gibraltar transform and Tell-Atlas belt using seismicity catalogs, GPS data, and paleoseismology.

Researchers analyze seismic hazard and strain release patterns in this region. Key works include McKenzie (1972) with 2806 citations on Mediterranean active tectonics and Stich et al. (2003) with 266 citations on moment tensor solutions for Ibero-Maghreb earthquakes. Over 10 foundational papers from 1972-2014 provide data on plate motions and subduction history.

Key Challenges

Why It Matters

Mapping seismicity supports probabilistic hazard assessment for coastal populations in Portugal, Spain, Morocco, and Algeria. Stich et al. (2003) moment tensor inversions improve source mechanism understanding for the 1755 Lisbon earthquake recurrence risk. Faccenna et al. (2001) subduction models inform back-arc extension hazards in the Tyrrhenian Sea, while Baptista and Miranda (2009) tsunami catalog revisions guide NEAMTHM18 modeling by Basili et al. (2021) for evacuation planning.

Key Research Challenges

Sparse Seismicity Data

Low earthquake frequency in the Azores-Gibraltar transform limits catalog reliability (Stich et al., 2003). Moment tensor inversions for Mw 3.5-5.7 events require regional waveforms. Paleoseismology faces dating uncertainties in Tell-Atlas faults.

Complex Stress Regimes

Converging African-Eurasian plates produce variable fault plane solutions (McKenzie, 1972). GPS strain rates conflict with seismic moment release (Minster and Jordan, 1978). Back-arc extension complicates slab dynamics (Faccenna et al., 2001).

Tsunami Source Integration

Linking seismicity to offshore faults challenges probabilistic models (Baptista and Miranda, 2009). Historical tsunamis lack instrumental constraints (Papadopoulos et al., 2014). NEAMTHM18 requires unified earthquake-tsunami catalogs (Basili et al., 2021).
