Correlation of Phreatomagmatic Depositional Features with Eruptive Events at the Ukinrek Maars, Alaska

拟议的项目将把存款和个人 有记录的火山喷发事件的地层 阿拉斯加的Ukinrek Maars，为了了解 与蒸汽岩浆的喷发和就位有关 存款 我们的研究结果将提供一种推断 不同的蒸汽岩浆喷发风格， 火山爆发地的沉积物特征 没有观察到。 这项研究的根本原因是 是为了帮助理解 危险评估。 火山喷发通常 包括最具破坏性的“爆炸”事件 和所有喷发的危险。 具有根本 危险评估必须认识到这些 存款，因为他们通常被误认为是重新加工 火山沉积物

The proposed project will correlate deposits and individual strata with recorded hydrovolcanic eruptive events at the Ukinrek Maars, Alaska, in order to understand the processes involved in eruption and emplacement of phreatomagmatic deposits. Our results will provide a means for inferring diverse phreatomagmatic eruption styles from the characteristics of deposits in places where the eruptions were not observed. The underlying reason for this research is to aid understanding of hydrovolcanic processes for hazards assessments. Hydrovolcanic eruptions commonly include "blast" events that are among the most devastating and hazardous of all eruptions. It is of fundamental importance for hazards evaluations to recognize these deposits, as they are commonly mistaken for re-worked volcanic deposits.
