雷雨中闪电殛树,把树劈断、烧焦、劈成碎块、把树皮从梢到根劈裂的现象有不少人见到过。可是闪电直接击到地上又会怎样呢? 不久前,美国密歇根有两个小孩在危南斯湖附近玩时,发现一个奇怪的东西半埋在地里,他们刮去附着的泥土后,看到一根直插入地的玻璃质长管,约5米长,为白、绿、灰色。两个孩子较懂事,以为是恐龙化石而没有敲碎,就让他们父母给密歇根大学古生物博物馆打电话,D. C. 菲舍尔博士去了一看,发现是闪电熔岩管。 Thunderstorm lightning trees, the tree split, scorched, split into pieces, the bark from the shoot to the root split phenomenon that many people have seen. But what about lightning going straight to the ground? Not long ago, when two children in Michigan, Michigan, were playing near Lake Guernsey, they found a weird thing half buried in the ground. They scrape off the attached soil and saw it A glass tube inserted straight into the ground, about 5 meters long, white, green, gray. The two children were more sensible, thought to be dinosaur fossils without cracking, and asked their parents to call the University of Michigan Paleontology Museum. Dr. D. Fischer looked at it and found it to be a lightning lava tube.
