Seismic sections show the response of the earth to seismic waves. 地震剖面是地殼對地震波的響應。
Seismic waves move out from the focus of an earthquake in all directions. 地震波從震中向周?chē)母鱾€(gè)方向傳播。
When the blast wave expands, it breaks the bubbles and thereby loses energy. 爆震波擴張時(shí)，會(huì )由氣泡吸收，因而喪失能量。
When this happens, seismic waves travel faster than usual through the rock. 當這種情況發(fā)生，震波穿過(guò)巖石的移動(dòng)速度要比往?？?。
By sheer coincidence, a trio of earth-monitoring satellites gave modelers the pristine, undistorted wave heights they needed for the Indian Ocean tsunami. 十分巧合的是，有一組地球觀(guān)測衛星提供了最原始且如實(shí)的海嘯波高值，這是模型設計師模擬印度洋海嘯時(shí)不可或缺的。
