Dike-Fault Interactions during the 2009 Harrat Lunayyir Dike Intrusion

The northwester Saudi Arabia was regarded as seismically quite region, but between April and June 2009 a swarm of more than 30000 earthquakes with a peak Mw 5.7 shock on May 19, took place in at the Harrat Lunayyir, one of the lava fields in the province. The main swarm period and the late stages of the swarm have been studied using multiple Envisat, ALOS and TerraSAR-X data [Pallister et al., 2010; Baer et al., 2010]. A series of Envisat data in wide swath mode before the main period of deformation are also available, which have not been investigated. They will probably be able to tell us the evolution of dike opening. In this project, I am going to use these data to study the deformation precursory to the 2009 Harrat Lunayyir dike intrusion as well as ground deforamtion during post-diking period.
