What is the magnitude of the Blind Thrust / Northridge earthquake?

The Northridge earthquake, which occurred on January 17, 1994, had a magnitude of 6.7. This magnitude was determined through seismological studies and has been widely accepted in literature and by geological organizations.

Understanding the significance of a 6.7 magnitude earthquake is crucial, as it provides insight into the energy released during the event and the potential effects it had on the surrounding areas, such as infrastructure damage and human safety. The Northridge earthquake was particularly notable due to its impact on the San Fernando Valley and Los Angeles areas, causing widespread destruction and resulting in numerous casualties.

The other magnitudes listed do not accurately represent the recorded magnitude of the Northridge event based on seismic data. Recognizing the correct magnitude helps in evaluating the seismic risk and planning for future earthquake preparedness in similar geological settings.
