Potentially induced earthquakes during the early twentieth century in the Los Angeles Basin
Susan E. Hough, Morgan T. Page
2016, Bulletin of the Seismological Society of America (106) 2419-2435
Recent studies have presented evidence that early to mid‐twentieth‐century earthquakes in Oklahoma and Texas were likely induced by fossil fuel production and/or injection of wastewater (Hough and Page, 2015; Frohlich et al., 2016). Considering seismicity from 1935 onward, Hauksson et al. (2015) concluded that there is no evidence for significant induced activity...
