LDEO Participation In The EU-Sponsored Iceland Volcano Survey

9526233门克这项研究是欧洲科学家正在计划进行的冰岛大西洋中部山脊实验(MARIE)火山危险评估调查的辅助实验，该地区也是地震活动区。将部署几个地震阵列，以补充欧洲的覆盖范围，并针对使用横波来确定板块边界的地壳深层分段。关键的问题是，作为温度指标的地壳下部横波衰减是否沿平行于山脊的方向变化，以及这种变化是否与表示地表分段的中央火山有关，和/或与莫霍面上的热传输有关。这项研究是国家减少地震灾害计划的一部分。***

9526233 Menke This research is an ancillary experiment to the Mid-Atlantic Ridge in Iceland Experiment (MARIE) volcanic hazard assessment survey being planned by European scientists for the mid-Atlantic plate boundary in North Iceland, which is also an area of seismic activity. Several seismic arrays will be deployed that supplement the European coverage and which are directed to using shear waves to define the deep crustal segmentation of the plate boundary. The critical questions are whether lower crustal shear wave attenuation, which is taken as a proxy for temperature, varies along the ridge-parallel direction and whether this variation is related to the central volcanoes that express the surficial segmentation, and/or to heat transport across the Moho. This research is a component of the National Earthquake Hazard Reduction Program. ***
