The Great Alaska Earthquake, which struck on March 27, 1964, had a magnitude of 9.2 on the Richter scale. It is the most powerful earthquake recorded in North American history and caused significant destruction and loss of life. The earthquake lasted for approximately 4.5 to 5 minutes, generating extensive tsunamis that affected coastal regions across the Pacific.

Is it possible for an earthquake to be off the scale?
Yes, it is possible for an earthquake to exceed the maximum intensity values on standard earthquake measurement scales like the Richter scale. In such cases, the magnitude may be estimated using other methods such as moment magnitude (Mw) or the earthquake may be classified as "great" or "major" based on its impact.
What is the maximum intensity of earthquake in the whole world?
The maximum intensity of earthquakes is typically measured using the Moment Magnitude Scale (Mw), with the strongest recorded earthquake being the 1964 Great Alaska Earthquake, which had a magnitude of 9.2.
