Scientists from the U.S. Geological Survey may have information that suggests oil drilling may have triggered earthquakes in the Los Angeles region, including the 1933 tragedy that resulted in more than 100 casualties, according to The Orange County Register.
The researchers reviewed historical records, identifying several quakes in the 1920s and 1930s that could have been caused by industry activity. The study included the 6.4 magnitude quake that struck Long Beach in 1933.
The Long Beach quake occurred shortly after drillers began drilling at different angles. The complete findings appear in the Oct. 31 edition of the Bulletin of the Seismological Society of America.
Additionally, the study does not point directly to a current risk as drilling techniques have changes.
