geologically

Apollo astronauts used seismometers during their visits to the Moon and discovered that the gray orb isn't a totally dead place, geologically speaking..阿波罗航天飞船的宇航员们登月时使用地震检波器发现：这个灰色的星球，从地质学角度上讲，并不完全是一个死气沉沉的地方。

"It know it sounds horrible to say this, but geologically speaking, it was not a big earthquake at all," says Alessandro Martelli, a professor of antiseismic engineering at the University of Ferrara..我知道这样说可能让人反感，但从地质学角度看，这并算不上太严重的地震，费拉拉大学地震预防工程师亚里山大.马特利说。

The Nabro volcano has not erupted in recorded human history, but lava flows near the volcano are relatively recent geologically..在有人类记载的历史中，纳布诺火山并未喷发，但火山附近的熔岩流是相对较新的地质。
