7 in) was estimated. It was attributed to the right fault along the Late Quaternary Fault. The Creek is a tributary of the San Andreas Fault system. The proximity of the epicenter to the Coachella Valley segment, a particularly dangerous part of the San Andreas fault, immediately raised concerns that it could be a precursor to a larger earthquake. This prompted the California Department of Emergency Services to issue a warning of possible future activity in the local counties shortly after the earthquake.

The Governor's Office of Emergency Services issued advisories to six counties telling officials in Riverside, San Bernardino, Imperial, Los Angeles, Orange, and San Diego counties that they should be on alert for another, larger quake. 433:

Of the 170 public school facilities in the earthquake's geographic area, 10 had minor structural damage, ranging from cracks in plaster to hairline cracks in masonry walls. 48 bridges were inspected after the earthquake, and 13 showed signs of movement, nine of which were slightly damaged. None of the bridges suffered damage severe enough to affect its traffic.

Although this earthquake did not have surface faulting that was observed, the rupture propagated northward 12 miles (19 km) to the town of Joshua Tree, where it caused damage. It caused minor damage to several bridges and minor architectural damage to public school buildings. A supermarket was

The magnitude 6.2 earthquake that occurred in Joshua Tree, California, on April 22, 1992, was a previously unmapped north-facing earthquake located about 20 km south of the Mount Pinto fault and about 10 km northeast of the mission and a maximum fault slip of 0.8 m (2 ft

The Joshua Tree mainshock struck at 9:50:25 p.m. It was caused by north-northwest-trending, right-lateral strike-slip faulting on the Eureka Peak fault which is at least 15 km (9.3 mi) long and possibly handles a significant portion of the slip transferred from the
