2021 Cumbre Vieja volcano eruption (La Palma, Spain) SfM DSM, Sep 2021

Digital surface model of the Cumbre Vieja new volcano edifice and lava flows (La Palma, Spain) as of 27 September 2021, produced from 915 UAS derived aerial photographs using the Structure-from-Motion method. The 2021 eruption of Cumbre Vieja volcano is the largest eruptive event in recorded history for La Palma Island (Canary Island, Spain). Over almost 3 months (September 19 - December 13, 2021), the volcano produced profound morphological changes in the landscape affecting both the natural and the anthropic environment over an area of tens of km2. The model shows numerous volcanic features including the new main edifice, lava flows, rafted material on lava flows, and tephra deposits.

基于2021年9月27日所摄得的915张无人机航空照片，运用结构光运动法构建的Cumbre Vieja新火山构造及熔岩流数字表面模型（位于西班牙拉帕尔马岛）。2021年Cumbre Vieja火山爆发是该岛（西班牙加那利群岛）有史以来最大的喷发事件。在几乎3个月的时间（2021年9月19日至12月13日）内，该火山引发了地貌的深刻变化，影响范围达数十平方公里，涉及自然环境和人文景观。模型展示了众多火山特征，包括新主构造、熔岩流、熔岩流上的漂移物质以及火山灰沉积物。
