1986年春阿拉斯加圣奥古斯丁火山喷发期间，人们担心火山的一部分坍塌到库克湾浅水中可能会引发海啸。在1883年的一次喷发中，火山和随之而来的海浪也发生了类似的建筑物倒塌。世界各地沿海火山喷发还产生了其他海浪，造成了巨大的生命和财产损失。尽管圣奥古斯丁火山在这一喷发周期中完好无损，但1883年事件的可能重演刺激了对1883年海浪的数值模拟。这一模拟产生了对潜在波高和旅行时间的预测，所基于的方法可以普遍适用于其他沿海火山。
During an eruption of the Alaskan volcano Mount St. Augustine in the spring of 1986, there was concern about the possibility that a tsunami might be generated by the collapse of a portion of the volcano into the shallow water of Cook Inlet. A similar edifice collapse of the volcano and ensuing sea wave occurred during an eruption in 1883. Other sea waves resulting in great loss of life and property have been generated by the eruption of coastal volcanos around the world. Although Mount St. Augustine remained intact during this eruptive cycle, a possible recurrence of the 1883 events spurred a numerical simulation of the 1883 sea wave. This simulation, which yielded a forecast of potential wave heights and travel times, was based on a method that could be applied generally to other coastal volcanos.
