The 1999 Hector Mine earthquake in southern California (magnitude 7.1) occurred only 20 km from, and 7 years after, the 1992 Landers earthquake (magnitude 7.3). This fault geometry and slip pattern presents a puzzle, because the northwest branch of this system should be in the stress shadow of the north branch, upon which nucleation likely took place. The surface rupture and seismicity patterns of the 1999 Hector Mine earthquake present somewhat of a puzzle to earthquake modelers. The October 16, 1999 Hector Mine earthquake provided an opportunity to test those procedures (Dreger and Kaverina, 2000). The 1999 Hector Mine earthquake occurred on October 16 at 02:46:50 PDT with a moment magnitude of 7.1 and a maximum Mercalli intensity of VII (Very strong).

On October 16,1999 I was first out,sound asleep, in room 259 in the Union Pacific's Yermo Railroad Inn, affectionatly known as THE BEANERY. Stress changes in the crust due to an earthquake can hasten the failure of neighbouring faults and induce earthquake sequences in some cases1,2,3,4,5. Up Next. Two recent large earthquakes in the Mojave Desert, California-the magnitude 7.3 1992 Landers and magnitude 7.1 1999 Hector Mine earthquakes-have each been followed by elevated crustal strain rates over periods of months and years. At about quarter to 3 AM a 7.1 earthquake woke me and a lot of other people up. The 1999 Hector Mine earthquake occurred on October 16 at 02:46:50 PDT with a moment magnitude of 7.1 and a maximum Mercalli intensity of VII (Very strong). The train was traveling near the epicenter when the quake struck. However, by the time of the Hector Mine earthquake the rapid postseismic deformation due to the Landers earth- These articles not only build and expand upon the preliminary results of USGS, SCEC, and CDMG (2000), but they also describe and analyze crustal deformation before, during, and after the earthquake The Hector Mine earthquake occurred in the central Mojave Desert and produced several meters of slip along faults of total length ~40 km. HYPOCENTRAL DEPTH: 0.01 km 1999 Izmit, Turkey (Toksoz et al., 1999), and 1999 Hector Mine, California (Scientists from the USGS et al., 2000), events have emphasized that strike-slip earthquakes com-monly take place on faults that display multiple offset fault segments with gaps and different orientations. But within about 10 seconds it was over, having ruptured in both directions (bilaterally) from the epicenter: north along the Lavic Lake fault for about 15 kilometers, and south along the Lavic Lake fault and the central Bullion fault for another 26 kilometers. Interactive Map. to the 1999 Hector Mine earthquake, its effects, and the re-gional geologic and tectonic setting. 41 km (26 miles) However, two major earthquakes have occurred in the Mojave Desert in 1992 (Landers) and 1999 (Hector Mine). To install click the Add extension button. Earthquake.
