9725405 Buffler The southern Red Sea-northern Danakil region of Eritrea is located at the northern apex of the Afar depression, which represents a major plate boundary triple junction underlain by an upwelling mantle plume. Here three active continental rifts converge and three major plates are separating with the formation of oceanic crust. Recent circumstances have allowed research efforts in this active area to address several tectonic rift processes, tectonic inversion, and controls on rift sedimentation and hominid paleontology. Results are expected to provide tectonic and geologic framework data in support of hominid studies as well as providing insight into near-triple point rift processes.

小行星9725405 厄立特里亚红海南部-北方达纳基尔地区位于阿法尔凹陷的北方顶点，这是一个主要的板块边界三联点，下面是一个上涌的地幔柱。 在这里，三个活跃的大陆裂谷汇聚，三个主要板块随着洋壳的形成而分离。 最近的情况下，允许在这个活跃的地区的研究工作，以解决几个构造裂谷过程，构造反转，裂谷沉积和古人类生物学的控制。 预计结果将提供构造和地质框架数据，支持人科动物的研究，以及提供洞察近三相点裂谷过程。
