Seismicity Processes In The Charlevoix Seismic Zone, Eastern Canada, Azadeh Fereidoni
Seismicity Processes In The Charlevoix Seismic Zone, Eastern Canada, Azadeh Fereidoni
Electronic Thesis and Dissertation Repository
The Charlevoix Seismic Zone (CSZ) is the most seismically active region in eastern Canada, based on the historical and current rate of activity. Several papers contend that the current seismicity in the CSZ represents long-lived aftershock sequences of the 1663 M~7 earthquake, in which the aftershock activity has persisted for hundreds of years. The aim of this thesis is to explore the influence of the 1663 earthquake on the current seismicity in the CSZ. The first part of the thesis has focused on developing a comprehensive earthquake database required for analysis of seismicity. The second part of the thesis has …
Magnitude Estimation For Earthquake And Tsunami Early Warning Systems, Attieh Eshaghi
Magnitude Estimation For Earthquake And Tsunami Early Warning Systems, Attieh Eshaghi
Electronic Thesis and Dissertation Repository
In this study, different magnitude estimation methods were investigated for application to earthquake early warning (EEW) and tsunami early warning systems. This integrated study is divided into two main parts. First, I used strong motion accelerograms recorded by borehole and surface stations from the Kiban Kyoshin network (KiK-net) for Japanese earthquakes with moment magnitude (M) ≥ 5.0 in order to develop ground motion prediction equations (GMPEs). I developed new GMPEs for peak ground acceleration (PGA) and peak ground velocity (PGV) using two different catalogs. The first catalog included earthquakes with 5.0 ≤ M ≤ 8.1 from 1998-2010. In …
Statistical Analysis And Computer Modelling Of Volcanic Eruptions, Laura Anabelle Sanchez
Statistical Analysis And Computer Modelling Of Volcanic Eruptions, Laura Anabelle Sanchez
Electronic Thesis and Dissertation Repository
Volcanism is an important mechanism by which internal heat is transported to the Earth's surface and volcanic eruptions are the results of the dynamics of a complex system and are characterized by non-trivial temporal correlations. Understanding the processes involved in volcano formation and magma ascent are crucial to develop better hazard assessment techniques. This study focuses on three main points: understanding caldera formation in the solar system, investigating the global temporal behaviour of volcanic eruptions and understanding the nonlinear interactions taking place in the solid crust which lead to an eruption.
In chapter 2, I first examine the distribution of …
