Project description

In the Central Apennines (Italy) there are many active normal faults throughout the Abruzzo and Umbria regions, these have been active for the past couple of million years and contribute to the high seismic hazard in the region. Earthquakes that occur are typically around magnitude 6, these earthquakes often cause damage to buildings in villages and cities, leading to the loss of lives in affected communities

During the course of my PhD, I will be investigating a series of earthquakes from 1703. Three earthquakes occurred between the 14th January and the 2nd February 1703 AD on three adjacent faults in series (from the NW to the SE). This sequence has an excellent record of damage to the surrounding villages, and it is unique in the catalogue of historical earthquakes in Italy, because these events are likely to have triggered each other in sequence. Part of my PhD aims to test this hypothesis, using structural mapping, Coulomb modelling and cosmogenic dating to try and understand how this sequence occurred. Faults further to the north-west and south-east (along strike) did not rupture in this sequence, so I also aim to try and understand why these faults did not rupture, even though they experienced an increase in stress. I will also be structurally mapping several faults in Umbria, to obtain the kinematics of these poorly studied faults, to add to existing strain maps of the region.
