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. ***

小行星9526233 这项研究是欧洲科学家计划在冰岛北部中大西洋板块边界进行的冰岛中大西洋海岭实验（玛丽）火山危险评估调查的辅助实验，冰岛北部也是一个地震活动区。 将部署几个地震台阵，以补充欧洲的覆盖范围，目的是利用剪切波确定板块边界的地壳深部分段。 关键的问题是，是否下地壳剪切波衰减，这是作为一个代理的温度，变化沿着洋脊平行的方向，以及这种变化是否与中央火山，表达的表层分割，和/或热输运跨越莫霍面。 这项研究是国家地震减灾计划的一个组成部分。 ***
