Monday we began to study The Great Alaskan Earthquake of 1964. We used a copy of the seismogram (shown above) from the great earthquake to help us in our investigation. This earthquake (that registered 9.2 on the Richter Scale) and its aftershocks lasted for two days (March 27 & 28) and rendered over 1,000 aftershocks, countless tsunami waves, and numerous lives lost.
During this class today we discussed the different aspects of the seismogram and also discussed how to read it. By doing this we were able pin point at what time the first P-Wave was recorded (7:40 pm) and also track and record at what times the aftershocks occurred.
Listed below is a link to some great information about the earthquake, aftershocks and tsunami’s that occured on this Good Friday on March 27th 1964.
