Which earthquake had a magnitude of 7.3 and resulted in one death while triggering movements on 10 additional faults?

The earthquake being referenced is the Landers earthquake, which occurred on June 28, 1992. This significant seismic event had a magnitude of 7.3 and is notable not only for its intensity but also for the relatively low human impact, reflected in the reported one death. Additionally, it was unique in that the earthquake triggered movements on multiple other faults in the region—specifically, it activated ten additional faults. This phenomenon is often referred to as fault interaction or complex seismic response, where the stress changes from one earthquake lead to failure on neighboring faults.

Understanding the context of major earthquakes and their impacts helps in assessing both their direct effects and the broader implications on fault systems. The Landers earthquake serves as a case study for examining fault behavior in a geologically complex area, demonstrating how one significant seismic event can influence the stability of surrounding fault lines.
