Geophysics The response of crustal rock to stresses is challenging to estimate yet vital for determining risks from events such as earthquakes. Moore et al. take advantage of the recent M w 7.1 Kumamoto earthquake in Japan to determine the rheology of crustal rocks in the region. The observed inversion of the crustal strain rates demonstrates that certain areas have stiff rock and others (e.g., under the Aso volcanic complex) have much weaker rock. The results match up with expectations, which means that the method can successfully measure rock properties over a wide range of strength and large spatial and temporal scales.

来自外太空的地壳岩石强度

地球物理学 地壳岩石对应力的响应具有挑战性，但对于确定地震等事件的风险至关重要。摩尔等人。利用日本最近发生的 M w 7.1 熊本地震来确定该地区地壳岩石的流变学。观察到的地壳应变率的反演表明，某些地区有坚硬的岩石，而其他地区（例如，在阿苏火山复合体下）的岩石要弱得多。结果与预期相符，这意味着该方法可以成功测量大范围强度和大空间和时间尺度上的岩石特性。科学，这个问题 p。[163][1][1]：/lookup/doi/10.1126/science.aal3422
