The ruptures rarely spread to shallow depths. Scientists believe the fault's odd behavior is explained by its varied textures -- corrugated patterns created by subduction activity."Our new imagery shows large variability in the conditions along the megathrust, which may be linked to a number of earthquake phenomena we observe in the re...

Finally, he packed his bags, determined to make his future in Miami i
