Silicon wafer production has been suspended at factories owned by Shin-Etsu Chemical and MEMC Electronic Materials, which together account for 25% of the global silicon wafer production. The suspension is expected to drastically impact semiconductor production, which is contingent on wafer availability. Some economic analysts consider that, ultimately, the catastrophe will improve Japan's economy, with increased job availability during restoration efforts. An analyst at JPMorgan Chase, citing the 1989 Loma Prieta earthquake in the San Francisco Bay Area and the Southern California 1994 Northridge earthquake, noted that
1989 Loma Prieta earthquake is the most studied fault on Earth. Andrew Lawson, a geologist from the University of California, Berkeley, had named the fault after the San Andreas Lake (prior to the occurrence of the 1906 San Francisco earthquake) and later led an investigation into that event. The San Andreas Fault ruptured for a length of during the 1906 shock, both to the north of San Francisco and to the south in the Santa Cruz Mountains region. Several long term forecasts for a large shock along the San Andreas Fault in that area had been made public prior to 1989 (the event and
