] Fault or Balcones Fault Zone is an area of largely normal faulting [1] in the U.S. state of Texas that runs roughly from the southwest part of the state near Del Rio to the north-central region near Dallas [2] along Interstate 35. The Balcones Fault zone is made up of many smaller features, including normal faults, grabens, and horsts. [3]

The Edwards Plateau is a geographic region forming the crossroads of Central, South and West Texas, United States.It is named in honor of Haden Edwards. [2] It is bounded by the Balcones Fault to the south and east; the Llano Uplift and the Llano Estacado to the north; and the Pecos River and Chihuahuan Desert to the west. [3]
A map of the Juan de Fuca plate with noted seismic incidents, including the 2001 Nisqually earthquake. The Juan de Fuca plate is bounded on the south by the Blanco fracture zone (running northwest off the coast of Oregon), on the north by the Nootka Fault (running southwest off Nootka Island, near Vancouver Island, British Columbia) and along the west by the Pacific plate (which covers most of ...
These lines allow tectonic plates to move and earthquakes occur when two plates slide past each other. The Ramapo Fault System is the longest in the northeastern U.S., stretching from Pennsylvania ...
A simulation of a plausible major southern San Andreas fault earthquake — a magnitude 7.8 that begins near the Mexican border along the fault plane and unzips all the way to L.A. County's ...
The fault that ruptured beneath New Jersey on Friday morning was likely an ancient, sleeping seam in the Earth, awakened by geologic forces in a region where earthquakes are rare and seismic risks ...
Wonder Cave is a show cave located in the Balcones Fault in San Marcos, Texas. Its entrance is one mile southwest of the Hays County Courthouse. The cave is reported to be the only commercially operated dry-formed cave in the United States ("dry-formed" because the fissure was opened not by erosion but by the earthquake that produced the ...
