At nearly 1,500 acres, Whittier Narrows is one of Los Angeles County’s largest and most popular recreation areas. 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. Try visiting some of these mapping information sites: National Fire Situational Awareness; NOAA Map for animated smokeplumes 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?

export interchange files (.e00 filename extensions) and as standard ARC coverages. The Whittier Fault Zone extends approximately 24 miles from Whittier Narrows in Los Angeles County, southeast to Santa Ana Canyon where it merges with the Elsinore Fault Zone.

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. A sizable quake struck this fault in 1933 creating extensive damage. 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. One seismologist stated that Friday's quake occurred in almost the exact same location as the Whittier Narrows earthquake in October of 1987. 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. Welcome to Whittier Narrows Golf Course. Black lines are faults, dashed where blind. Fault segments are labeled as LA (Los Angeles), SF (Santa Fe Springs) and CH (Coyote Hills). Text is available under the CC BY-SA 4.0 license, excluding photos, directions and the map. fault is able to produce a seismic event of magnitude 6.0 or greater. It was recorded at a depth of about 10.9 miles. 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. Whittier Fault is exposed along the southern slopes of the Puente Hills and has a length of approximately 25 miles, between the Whittier Narrows at the northwest and the Santa Ana River to the southeast (Heathcote Geotechnical 2011). Whittier. 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 … Data from Shaw and Shearer (1999) and Shaw et al. There is also the Whittier Narrows fault which is probably same distance to the Northeast. 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. Explain your answer using information from the map. pictured in Figures 2 and 3 are shown as bold gray lines. 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. Where Is The Whittier Fault? of the 1987 Mw 6.0 Whittier Narrows focus. Based on an analysis of these folds, we produce Quaternary slip profiles along each ramp segment. https://www.alltrails.com/parks/us/california/whittier-narrows-recreation-area ... Whittier Narrows. Figure simplified from Rollins et al. It was believed to be located (felt strongest) in the area of East Whittier, which had ($50,000-$350,000) damage. 5.9. The Elysian Park Fault is located approximately 15 to 20 miles north of the City in the Montebello and Monterey Park areas. Studies have shown that this blind thrust fault can cause an earthquake of a magnitude ranging from 6.6 to 7.5. [2018]. 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. 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 … “Beach balls” show the locations and senses of slip of the 1971 Sylmar, 1987 Whittier Narrows and 1994 Northridge earthquakes. 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. 8.

Figure 2. This list covers all faults and fault-systems that are either geologically important or connected to prominent seismic activity. It … 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). Larger image SCEC Community Fault Model This map shows the 3-dimensional structure of major faults beneath Southern California. 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. Scientists have not detected an earthquake on the Whittier fault in modern history. 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. Vertical faults such as the San Andreas (red band from top left to bottom right) are shown as a thin strip. According to famed seismologist Dr. Lucy Jones, the quake was in almost the same location as the magnitude 5.9 Whittier Narrows earthquake in 1987.
