I investigated rifts in multiple stages of their formation, from the failed Mid-Continent Rift (MCR), to the active Red Sea Rift. Each rifting stage presents its own challenges but by studying each stage individually I have gained insight into the rifting process. The MCR, an an…

A rifting episode started in September 2005 with an intrusion of a 60 km-long mega-dike along the Dabbahu-Manda Hararo (DMH) rift segment in Afar, Ethiopia. Between 2005 and 2009 thirteen smaller volume dikes intruded different portions of the rift segment. Out of the 13 dikes, …

The reinforcement detailing of reinforced concrete frame and wall-frame structures, in regions where the probability of a seismic event is not significant, is characterized by lack of special consideration for meeting ductile response requirements. The buildings are normally des…

This dissertation presents a global strain rate model in which the style, direction and magnitude of crustal strain rates are determined jointly with a model surface velocity field as well. The model includes 2933 geodetic velocities from 50 different studies. Some Quaternary fa…

Identification and characterization of the Paleozoic Suwanee basin sedimentary sequence and the associated Pangea supercontinent transcurrent fault are critical in furthering our present understanding of tectonic history and its impacts today. However, explicit bounding of the S…
