Alaskan earthquakes of 1899

Abstract

Introductory THE EARTHQUAKES AND THEIR RESULTS The severe earthquakes in the Yakutat Bay region, Alaska, in September, 1899, were accompanied by faulting, tilting and warping, by changes of level along the coast, and by glacial oscillations, some of which are still in progress. These have already been described. 2 The earthquakes themselves, however, were only briefly referred to in the reports published. It is the purpose of the present paper to describe these earthquakes. They lasted 27 days—September 3 to 29, 1899—and included four or five world-shaking disturbances and hundreds of minor shocks. During four weeks there was almost constant palpitation of this part of the earth’s crust. The shocks were most severe on September 3, 10, and 23, and were great on the 15th, 17th, 26th, and 29th (figure 6). On the 10th there were over 50 small shocks and two world-shaking disturbances. The greatest faulting took place on September . . .
