What was the magnitude of the Johnson Valley / Landers earthquake?

The Johnson Valley/Landers earthquake, which occurred on June 28, 1992, was magnitude 7.3. This earthquake was notable not only for its size but also for the impact it had on the region, resulting in significant surface rupture and alteration of the landscape.

A magnitude of 7.3 indicates a major seismic event capable of causing considerable damage, especially in populated areas. This specific earthquake is often studied in seismology due to its characteristics and the tectonic setting of Southern California, which is characterized by complex fault systems and historical seismic activity.

Understanding the magnitude helps in assessing the potential damage and risk associated with such events, highlighting the importance of accurate seismic data in planning and response efforts following significant earthquakes. This event also contributes to the body of knowledge used for earthquake preparedness and building regulations in seismically active regions.
