A comprehensive study of the seismotectonics of the eastern Aleutian arc and associated volcanic systems
This report covers progress for a one-year period from April, 1989 to April, 1990 of an ongoing comprehensive research project of subduction processes of the Alaska-Aleution trench-arc system. Our studies range in scale from analyses of the tectonics of the entire Alaskan convergent system, to detai...

Summary: | This report covers progress for a one-year period from April, 1989 to April, 1990 of an ongoing comprehensive research project of subduction processes of the Alaska-Aleution trench-arc system. Our studies range in scale from analyses of the tectonics of the entire Alaskan convergent system, to details of individual earthquake ruptures in the Shumagin seismic gap and in the Gulf of Alaska. They range in time from the earliest recorded events along the arc to rapid computer processing of the latest seismic and volcanic events. By integrating results from many perspectives we seek new quantitative understanding of fundamental processes in subduction systems. 21 refs., 12 figs. |
