2000年三宅岛火山爆发，三宅岛的植被遭到严重破坏。为了掌握三宅岛植被长期和广泛的影响，分析了四个卫星图像。第一个可见的植被破坏是山顶上的植被灭绝，沿着形成了一个破火山口。在2000年7月至2000年8月火山活动的主要阶段，岛上几乎所有植被都受到火山灰的破坏。火山口周围植被破坏极其严重，火山灰存款较厚。在山脚下，火山灰造成的植被破坏正在逐步恢复。2000年秋季以来，植被破坏向东、西南部地区蔓延。这种植被的主要可能因素是自2000年9月以来排放的火山气体。
Vegetation in Miyake Island was severely damaged by the 2000 Miyake Island volcano eruption. Four satellite images were analyzed for the purpose of grasping the long-term and extensive effect on vegetation of Miyake Island. The first visible vegetation damage was extinction of vegetation on the top of the mountain along with a caldera formation. During the main phases of volcanic activity occurred from July 2000 to August 2000, almost all vegetation in the Island were damaged mainly by volcanic ash. The vegetation damege was extremely severe around the crater where volcanic ash deposit was thick. On the foothill of the mountain, vegetation damage caused by volcanic ash was gradually recovered. However, vegetation damege was spreading out to the eastern and southwestern area of the mountain since autumn 2000. The main possible factor of this vegetation is volcanic gas emitted since September 2000.
