Some sections of the San Andreas Fault system in San Francisco Bay Area are locked, overdue

  1. 1. Regarding this sentence from the article: "Monitoring of creep on Bay Area faults has expanded in recent years"

    • Good. Saving lives is important.

    • I'm glad they're monitoring it and I certainly don't want to see Californians die, but I wonder if this recent expansion uses tax dollars courtesy of President Hussein Obama.

    • Scientists shouldn't be playing God. If the Lord intends for Californians to die in a massive quake, so be it.

    • I hate California too much to read this article. California sucks.

Four urban sections of the San Andreas Fault system in Northern California have stored enough energy to produce major earthquakes, according to a new study that measures fault creep. Three fault sections – Hayward, Rodgers Creek and Green Valley – are nearing or past their average recurrence interval, according to the study published in the Bulletin of the Seismological Society of America (BSSA).

The earthquake cycle reflects the accumulation of strain on a fault, its release as slip, and its re-accumulation and re-release. Fault creep is the slip and slow release of strain in the uppermost part of the Earth's crust that occurs on some faults between large earthquakes, when much greater stress is released in only seconds. Where no fault creep occurs, a fault is considered locked and stress will build until it is released by an earthquake.

...

Monitoring of creep on Bay Area faults has expanded in recent years. The alignment array measurements made by the San Francisco State University Creep Project and recently expanded GPS station networks provide the primary data on surface creep, which the authors used to estimate the average depth of creep for each fault segment.

...

According to the study, four faults have accumulated sufficient strain to produce a major earthquake. Three creeping faults have large locked areas (less than 1 mm or .04 inches of creep per year) that have not ruptured in a major earthquake of at least magnitude 6.7 since the reporting of earthquakes by local inhabitants: Rodgers Creek, northern Calaveras and southern Green Valley. The southern Hayward fault, which produced a magnitude 6.8 earthquake in 1868, is now approaching its mean recurrence time based on paleoseismic studies.
