Collaborative Research: Kinematics and Dynamics of Kilauea Volcano from GPS Observations

9903766欧文研究人员将扩大他们在基拉韦厄火山上的持续记录全球定位系统（GPS）网络，以更好地了解火山和地震变形。 将在最近几次大地震的震中地区增加两个GPS台站，其中最大的一次是7.2级地震。 年度测量意味着在1997年6月M5.5级地震前的几个网站的变形模式的变化。 新的监测站将有助于限制成核区内的变形速率变化。 调查人员将测试1997年6月地震前收集的数据是否可以用基拉韦厄下方滑脱层滑动率的下降来解释。 将开发快速分析GPS数据的技术，以确定近实时的变形估计，并对这些数据进行建模，以更好地约束地震和岩浆过程。

9903766 Owen The investigators will expand their continuously recording Global Positioning System (GPS) network on Kilauea volcano to better understand volcanic and seismic deformations. Two GPS stations will be added in the epicentral region of the most recent large earthquakes, the largest of which was M7.2. Annual measurements imply a change in the pattern of deformation at several sites prior to a M5.5 earthquake in June 1997. The new stations will help constrain deformation rate changes within this nucleation zone. The investigators will test whether the data collected before the June 1997 earthquake can be explained by a decrease in slip-rate on the decollement beneath Kilauea. Techniques will be developed to rapidly analyze the GPS data to determine near real-time estimates of deformation, and to model these data to better constrain seismic and magmatic processes.
