...second largest freshwater lake in the world in surface area.
It is located in the same region as Africas Great Rift Valley System, an area of tectonic

GPS Could Help to Identify High Risk Zones
...associations, claimed that GPS has been used to reveal the location of a locked zone to the west of Seattle.
Locked zones occur where adjacent tectonic
plates appear 'locked' together as a result of the friction between them. When the plates eventually overcome the friction and break free, the release...

The structure and dynamics of Earth's mantle are of great importance because they determine the forces acting upon tectonic
plates. Imaging the deep Earth is accomplished through seismic tomography, where variations in seismic wave travel times help to map out elastic heter...

Closure of the Isthmus of Panama involved a protracted sequence of volcanic and tectonic
