Seismic hazard assessments must consider different aspects that are involved in an earthquake process and affect the surface ground motion. Those aspects can be classified into three main kinds. 1) the source effects are related to the rupture process and the release of energy. 2) the path effects related to the propagation of energy inside...

Summary In 1906, an earthquake with a magnitude estimated between Mw 8.4 and 8.8 occurred in the subduction zone along the coast of Ecuador and Colombia. This earthquake caused extensive damage on the coast but had a rather small impact on the capital city of Quito, situated 180 km away. At that time, the city of Quito extended over a small...

The city of Quito (3M inhabitants), capital of Ecuador, is prone to seismic hazard and the associated risk is increasing due to its growing. The city has been damaged several times in the past by earthquakes that occurred on crustal faults around Quito or in the Cordillera (Beauval et al., 2010). As far as we know, the earthquakes that occurred...
