The charts Today are showing extreme stress building up after yesterdays 5+ quake everyone please make sure you have your emergency supplies Water, food , batties,flahlights ect. up to Date Todays Report...The overall effect is that lithospheric stress is higher than what it was prior to the revised M5.1 earthquake epicentered near Ludlow, CA. The situation has now become more ominous with the increased normal, or compressional stress level being much higher in amplitude.Overstressed faults may now begin reacting to the high compression level taking place along the Pacific-North American Plate Boundary within the region from Wrightwood, CA to the Salton Sea. Regimes that are local to the stress buildup include the San Jacinto Fault, Eastern Sierra Madre-Cucamonga Fault, Banning Fault, Pinto Mountain Fault, Cleghorn-Silverwood Lake Fault, Santa Ana Fault, Northern Frontal Thrust Fault, Lenwood Fault, and the Helendale Fault. The Southern San Andreas Fault from east of Wrightwood to the Coachella Valley is also under advisory to be prepared for more local seismic activity, which may include another moderate to strong earthquake closer in to populated areas within the Inland Empire.A Warning level means that frequent updates during the next 72 hours are absolutely required.As we all know earthquakes can not be predicted with 100% accuracy ....however the conditions that may prelude/ lead up to a quake are well documented This does not mean a quake is imminent just that conditions are right...better to prepared than not ...when one lives in EQ country

More info No available Shear Stress nucleating through the ECSZ indicates the Mojave Desert Block remains in a high lithospheric state of stress. The M5.1 earthquake provided no relief to what's been observed to be in the buildup phase for the past several months. Seismic activity epicentered north of the Mojave Desert Block is also increasing without movement of upper level shear stress through the ECSZ, which remains in a locked compressional condition. Meanwhile seismic activity along its peripheral edge is going to be increasing in both magnitude and intensity while this locked state continues to be in effect. The Buildup in compressional stress to the south near the Cajon Pass is also a major development in regard to the plate boundary's management of lithospheric stress. The usual mechanism for stress transfer into the secondary fault system has stopped working, and that will allow the Southern San Andreas Fault Zone to increase its stress level beyond what's considered normal. The stress regime remains in a compressional mode. Normally, the compression would be converted into upper level shear stress, which migrates into the secondary fault system at the Cajon Pass, and helps decrease the threat for having the next great earthquake. If the current buildup in compressional stress continues for much longer, that may be its end result.
