Exercise 2 Hayward Fault On-line Pre-Exercise Assignment Jong Park 1a. 1868 was when the last major earthquake occurred on the Hayward Fault. Its magnitude was 7.0. 1b. six to seven million people are threatened by a large earthquake on the Hayward Fault. 2a. The most recent estimate of the probability that one or more magnitude 6.7 or larger earthquakes will occur in the Bay Area in the next 30 years is 62%. 2b. The probability that one or more magnitude 6.7 or larger earthquakes will occur on the Hayward/Rodgers Creek fault segment in the next 30 years is 27%. 3a. Two types of movement that occur along faults are the catastrophic rupture and fault creep or tectonic creep. The catastrophic rupture can cause up to about three feet rupture in the fault. It is a visible breaking and displacement along the trace of fault. The breakage seen during a sudden earthquake would be an example of a catastrophic rupture. The fault creep, which is a very slow movement of the fault, can be observed by a few millimeters or a fraction of an inch a year deformation in streets and buildings. 3b. To say that the Hayward fault is a “right lateral” fault means that the fault causes a horizontal offset of the ground to the right side. (The right-side movement when one is facing the breakage)
