根据一项新研究，沿地壳构造板块边缘的地震带远比缺乏活动的地带更可能产生伟大的远古文明，研究者称这种联系说明通常被视为破坏性的地质能量，比如地震，在人类历史中或许也起过建设性作用。

Researchers say the relationship suggests that forces typically viewed as destructive--such as earthquakes--might have also played a constructive role in human history.

在板块的边缘发现世界上多数的火山，那儿的地质活动很剧烈。

Many of the world's volcanoes are found at the edges of plates, where geologic activity is intense.
