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.
