Volcano and Aurora in Iceland
Credit: Sigurdur H. Stefnisson
Explanation: Sometimes both heaven and Earth erupt. In Iceland in 1991, the volcano Hekla erupted at the same time that auroras were visible overhead. Hekla, one of the most famous volcanoes in the world, has erupted at least 20 times over the past millennium, sometimes causing great destruction. The last eruption occurred only six years ago but caused only minor damage. The green auroral band occurred fortuitously about 100 kilometers above the erupting lava. Is Earth the Solar System's only planet with both auroras and volcanos?作者: 夜空 时间: 2006-2-7 15:00
解释: 有时天空和地球同时在喷发。1991 年的冰岛, Hekla 火山 喷发的同时,极光也同时在天空中可见。Hekla, 世界最著名的火山之一, 在过去的一千年至少喷发过20次, 有时导致巨大破坏。最后一次爆发发生在六年前但仅仅造成较小损失。绿色极光 偶然地发生在喷发的熔岩大约100 公里之上。难道地球是太阳系中唯一有极光和活火山行星吗?作者: 夜猫子 时间: 2006-2-7 20:50
