| 41. | The Mount Diablo Thrust Fault is capable of generating an earthquake of magnitude M W = 6.7.
|
| 42. | The 1994 Northridge quake, linked to a blind thrust fault near Los Angeles, registered 6 . 7.
|
| 43. | Until now, most scientists believed blind thrust faults produced quakes of only up to 6 . 75-magnitude.
|
| 44. | They are thought to have combusted after the development of the Cerrej�n thrust fault and alluvial fan.
|
| 45. | Thrust faults lie at low angles, unlike the familiar vertical faults like the San Andreas and Hayward.
|
| 46. | Because of the lack of surface evidence, blind thrust faults are difficult to detect until they rupture.
|
| 47. | The hour explains how the Northridge temblor baffled the experts, coming on a previously unmapped thrust fault.
|
| 48. | Blind-thrust faults produce earthquakes when one block pushes upward over another, as if moving up a ramp.
|
| 49. | Thrust faults do so when one block pushes upward over another, as if moving up a ramp.
|
| 50. | They also hope to pinpoint previously unmapped thrust faults, like the one responsible for the deadly Northridge Earthquake.
