600 英里的卡斯卡迪亚俯冲带已被绘制，能够引发 9.0 级地震和 40 英尺高的海啸。 600-mile Cascadia subduction zone mapped, capable of generating 9.0-magnitude earthquakes and 40-ft tsunamis.
科学家们以前所未有的详细程度绘制了卡斯卡迪亚俯冲带地图，这是一条位于太平洋西北海岸 600 英里的地质边界。 Scientists have mapped the Cascadia subduction zone, a 600-mile geological boundary off the Pacific Northwest coast, in unprecedented detail. 该区域从加利福尼亚州北部延伸到温哥华岛，是一个板块滑动区，可能引发灾难性的 9.0 级地震和 40 英尺高的海啸。 The zone, which stretches from Northern California to Vancouver Island, is a tectonic plate slip area that can generate a catastrophic 9.0-magnitude earthquake and 40-foot-high tsunamis. 为了更好地了解地质状况并帮助政策制定者制定保护人们的建筑规范，研究人员一直在分析断层的几何形状并评估整个地区的风险。 To better understand the geological state of play and help policymakers devise building codes that protect people, researchers have been analyzing the fault's geometry and assessing the risk to the entire area.
