Volcanologist Dr. Marie Edmonds has dev漫画大全之无彩翼漫免费ised sensors that monitor the underground activity of magma to better predict future eruptions on the Caribbean island of Monserrat, the site of the massive 1995 eruption captured for this film.

Dr. Joshua Wurman and his team chase tornados in trucks equipped with Doppler rad另类 专区 另类 在线 视频ar in an attempt to probe the interior of a tornado just as it is born.
