Question

The Northridge and Landers earthquakes may be part of a pattern of increasing seismicity prior to failure along the segment of the San Andreas opposite Los Angeles. True False

Answer 1

True

Step-by-step explanation:

The Northridge earthquake took place on January 17, 1994 in the County of Los Angeles. The earthquake could be felt as far as Las Vegas, Nevada, and it had a death toll of 57, with more than 8,700 injured. On the other hand, the Landers earthquake took place on June 28, 1992 in Southern California. It had a magnitude of 7.3, and was much more powerful than the Northridge earthquake. Both of these are considered to be part of a pattern of increasing seismicity of the San Andreas fault.

Answer 2

The answer is True.

Step-by-step explanation:

In a research that combined seismic, geologic and geodetic data regarding Northridge and Landers earthquakes, and assessed the two earthquakes, the Poissonian and seismic hazard models showed that there was between 80 and 90 per cent probability that Northridge and Landers earthquakes may be part of a pattern of increasing before any type of failure along the southern segment of the San Andreas.
