由于P波和S 波以不同但相当恒定的速度传播，它们到达的间隔与到震源或初始破裂点的距离成比例地增加。
Because P and S waves travel at different but fairly constant speeds, the interval between their arrivals increases in proportion to the distance from the earthquake focus, or initial rupture point.
但是震源仅仅距地面5千米，是上次的一半，距离震中仅仅10千米，而上次则是30千米。
But at 5km (3 miles) down, its focus was at half the depth—and the epicentre a mere 10km from the city compared with 30km last time.
拥有70万人口的康塞普西翁市(concepcion)，距离震源115公里，一幢15层的公寓倒塌，100人被困。该市大学的生化实验室也发生了火灾。
In concepcion, a city of 700,000 people, 115km from the quake's source, a 15-storey block of flats collapsed, trapping 100 people, and a biochemical laboratory at the city university caught fire.
此次地震的震中距离中心城市仅20公里之遥，震源深度只有10公里，整个城市剧烈晃动。
With the epicentre only 20km from the central city and the quake only 10km deep, the whole city got a mighty shaking.
据报道，震中距离巴东海岸30英里，震源深度约53英里。
Its epicentre was reported to be about 30 miles offshore from Padang, at a depth of about 53 miles.
据美国国家地理调查局的调查，这次地震的震央在距离智利首都200英里(325公里)的圣地亚哥，地震源深度为22英里(35公里)的地下，发生时间是格林威治东部时间上午1点34分。
The quake hit 200 miles (325 kilometers) southwest of the capital, Santiago, at a depth of 22 miles (35 kilometers) at 3:34 a.m. (0634 GMT; 1:34 a.m. Est), the U.S. Geological Survey reported.
很明显，最大干扰距离与震源类型和激发条件有关。
Obviously, the maximum interference distance is related to source mode and shooting conditions.
在地表地震采集中，指震源到检波器的水平距离。
In surface seismic acquisition, the horizontal distance from source to receiver.
在垂直地震剖面中，偏移距是震源和井口之间的水平距离。在斜井的情况下，偏移距是震源和检波器在地表的投影之间的距离。
In a vertical seismic profile, offset is the horizontal distance between the source and the wellhead or the surface projection of the receiver in the case of a deviated well.
从震中到震源的距离叫震源深度。
From the epicenter of the distance to the source told focal depth.
震源浅的地震造成的破坏性更大，因为能量的释放距离地面更近，引发的震动更剧烈。
Shallow quakes cause more damage because the energy is released closer to the earth's surface and triggers stronger shaking.
震源浅的地震造成的破坏性更大，因为能量的释放距离地面更近，引发的震动更剧烈。
Shallow quakes cause more damage because the energy is released closer to the earth's surface and triggers stronger shaking.
