The new online maps show red quadrants indicating known fault zones laid over a California map. LOS ANGELES -- After the 1971 Sylmar earthquake, California began to map faults across the state.

The location and geologic circumstances of the Whittier Narrows earthquakes have demonstrated once again that damaging earthquakes occur almost anywhere in the Los Angeles region. Larger image SCEC Community Fault Model This map shows the 3-dimensional structure of major faults beneath Southern California. The Elysian Park Fault is located approximately 15 to 20 miles north of the City in the Montebello and Monterey Park areas. The magnitude 6.0 Whittier Narrows earthquake back in 1987 was generated from this fault system, and historical evidence shows that this fault system has generated at least four magnitude 7.2-7.5 earthquakes in the past 11,000 years. Still considered moderate at magnitude 5.9, that quake killed eight people and did more than $350 million in damage. Figure 2. One seismologist stated that Friday's quake occurred in almost the exact same location as the Whittier Narrows earthquake in October of 1987. Figure simplified from Rollins et al. Fault segments are labeled as LA (Los Angeles), SF (Santa Fe Springs) and CH (Coyote Hills). Elysian Park Fault. 1987. Where Is The Whittier Fault? Find parking costs, opening hours and a parking map of Whittier Narrows Recreation Area 750 Santa Anita Avenue as well as other parking lots, street parking, parking meters … Black lines are faults, dashed where blind. The Puente Hills fault system was previously unknown to scientists when it ruptured in 1987, causing the magnitude 5.9 Whittier Narrows earthquake that caused $358 million in … It was recorded at a depth of about 10.9 miles. The October 1, 1987, Whittier Narrows earthquake (M L = 5.9) was located at 34°2.96′N, 118°4.86′W, at a depth of 14.6±0.5 km in the northeastern Los Angeles basin.The focal mechanism of the mainshock derived from first motion polarities shows pure thrust motion on west striking nodal planes with dips of 25°±5° and 65°±5°, respectively. In 1987, the fault caused the Whittier Narrows earthquake. The other big ones here are Sylmar at 6.6, Whittier Narrows at 5.9, Sierra Madre at 5.8 and Northridge 6.7. Explain your answer using information from the map. Welcome to Whittier Narrows Golf Course. There is also the Whittier Narrows fault which is probably same distance to the Northeast. Significant Earthquakes and Faults Chronological Earthquake Index ... How well is this boundary characterized by the single line of the San Andreas Fault? A series of quakes caused significant damage and multiple deaths in the 1980s and 1990s, including the 1987 Whittier Narrows fault, a 5.9-magnitude temblor that … The PHT comprises three, north-dipping ramp segments that are overlain by contractional fault-related folds. One questions: Did the temblor make quakes more likely along more dangerous fault lines, such as the Whittier — which produced the deadly 1987 Whittier Narrows quake? It is not intended to list every notable fault, but only major fault zones. (2002). of the 1987 Mw 6.0 Whittier Narrows focus. Background shading is a measure of material stiffness at the surface based on the Community Velocity Model [Shaw et al., 2015]. There are no Maps at this time. Thanks to Mapbox for providing amazing maps. It was believed to be located (felt strongest) in the area of East Whittier, which had ($50,000-$350,000) damage. Geometry of the uppermost 7 km is constrained by high-quality petroleum-industry seismic reflection data, whereas the deeper fault geometry is constrained by the location of the 1987 mainshock focus and relocated aftershocks.

Line 1 was also situated for imaging the blind thrust fault system that caused the 1987 Whittier Narrows earthquake, the Sierra Madre fault system that caused the 1991 Sierra Madre earthquake, and the San Andreas fault. The 1987 Whittier Narrows earthquake occurred in the southern San Gabriel Valley and surrounding communities of southern California, United States, at 7:42 a.m. PDT on October 1. Scientists are particularly interested in the Whittier fault because it's connected to the Elsinore and runs under heavily populated areas. Based on the page Whittier Narrows. Whittier. Seismologists warned that a bigger earthquake from the Puente Hills thrust fault, which caused Friday night’s magnitude-5.1 quake in La Habra and … ... Whittier Narrows. In most maps of tectonic plates, this plate boundary is drawn along the San Andreas Fault, which stretches 1300 km (800 miles) across western California. The inset map shows the study area relative to downtown Los Angeles (LA), and the location and focal mechanism of the 1987 Whittier Narrows earthquake (M6.0). A sizable quake struck this fault in 1933 creating extensive damage. The moderate 5.9 magnitude blind thrust earthquake was centered several miles north of Whittier in the town of Rosemead, had a relatively shallow depth, and was felt throughout southern California and southern Nevada. The fault line is a branch of the quiet giant Elsinore Fault, and going east-to west the fault begins just north of SR 91, up and above Gypsum Canyon Road at Bryant Ranch Park near Bryant Ranch Elementary School in Yorba Linda. See this page's contributions. Wilson quadrangle, for example – will produce a grainy black-and-white map, a slender tangle of thin black lines running diagonally into the San Gabriel Valley mountains. 5.9. Studies have shown that this blind thrust fault can cause an earthquake of a magnitude ranging from 6.6 to 7.5. The Whittier Narrows quake occurred along a then-unknown fault that runs from Chino Hills to Whittier and is part of the larger Puente Hills Fault, which stretches from just west of … The Elysian Park Fault produced the 1987 Whittier Narrows 5.9 magnitude earthquake. Whittier Narrows (moment magnitude [M w] 6.0) earthquake and extends for more than 40 km along strike beneath the northern Los Angeles basin. The magnitude 5.6 Whittier Narrows earthquake in 1987, which caused destructive damage and killed eight people and $358 million in damage, actually occurred on the underground Puente Hills thrust fault, which lies under downtown L.A., the southern San Gabriel Valley and southeast L.A. County. It … A major quake occurred on this fault back in 1988 or 89. The park extends over the 60 Freeway and home to recreational facilities and activities that include a shooting range, equestrian trail, fishing area, picnic area, softball and soccer fields, bike paths as well as paved airstrip. This list covers all faults and fault-systems that are either geologically important or connected to prominent seismic activity. The focal point of the earthquake was almost the same location as the M5.9 Whittier Narrows earthquake in 1987, according to seismologist Dr. … The first earthquake attributed to the Whittier Fault and felt strongly in the Whittier area was an earthquake July 8, 1929 at 8:45am with an estimated magnitude of 4.7.
