南极洲Thwaites冰川附近探测到360多起冰山地震,表明与气候变化有关的冰雪迅速流失。
Over 360 iceberg quakes detected near Antarctica’s Thwaites Glacier, signaling rapid ice loss linked to climate change.
利用当地地震台站进行的一项新研究发现,南极洲Thwaites和松树岛冰川附近有360多起与冰山有关的地震,主要在Thwaites附近——称为“Domosday冰川”。
A new study using local seismic stations has detected over 360 iceberg-related quakes near Antarctica’s Thwaites and Pine Island glaciers, primarily near Thwaites—known as the "Doomsday Glacier."
这些冰川地震是由大规模冰山破裂和冰封化引起的,以前由于全球网络的低频信号而未被发现。
These glacial earthquakes, caused by massive icebergs breaking off and capsizing, were previously undetected by global networks due to their low-frequency signals.
2018年至2020年期间的峰值活动恰逢冰流加速,这很可能与海洋条件的变化相关联。
Peak activity from 2018 to 2020 coincided with accelerated ice flow, likely linked to changing ocean conditions.
松树岛冰川附近的第二个无法解释的集群突出显示了理解上的空白。
A second, unexplained cluster near Pine Island Glacier highlights gaps in understanding.
研究结果突出表明,有必要进行地方监测,以跟踪气候驱动的冰川变化和海平面上升风险。
The findings underscore the need for localized monitoring to track climate-driven glacier changes and sea-level rise risks.
