Aftermath of the 2011 Tōhoku earthquake and tsunami highest in the world). This additional spending could hurt demand for government bonds. 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 Beroza, a seismologist with Stanford University, made several distinctions regarding the 1906 and 1989 events. Near Loma Prieta, the 1906 rupture was more shallow, had more strike-slip, and occurred on a fault that was near vertical. The 1989 event's oblique-slip rupture was at 10 km and below on a fault plane that dipped 70° to the southwest. Because much of the slip in 1989 occurred at depth and the rupture propagated up dip, Beroza proposed that the overlying San Andreas Fault actually inhibited further rupture and also maintains that the occurrence of an event at the location that was forecast
