Abstract

Palmer Seismological Observatory has primary responsibility for tsunami warning in Alaska for Alaskan earthquakes. Large earthquakes can occur anywhere along the 2300 miles of coastline from Shemya to Sitka. The measurement of large earthquakes occurring in the net has prompted the development of several schemes for determining magnitude. Acceleration is considered here as a tool in the measuring of large earthquakes near Palmer. The ML method is related to acceleration graphically and mathematically. The largest earthquake available in this study is M 7.7 and it is barely in the range of events under consideration in this study. It is felt that acceleration eventually may be used in magnitude determination.
