地质学者认为断层是震源在地表的表现。
Geologist thinks that fault is the surface expression of focus.
地质监测数据显示最新一次地震震源距地表6.2英里。
Data from the geological survey indicated that the epicenter of the latest earthquake was 6.2 miles beneath the earth's surface.
但并不是所有的地表断裂都直接与震源的运动相联系，它们也可能是由于地震波造成的次生影响。
However, not all the fault surface and the source directly linked to the movement, they also may be due to seismic waves caused by secondary impact.
从震源垂直向上到地表的地方叫震中。
Source upward from the vertical to the surface where is the epicenter.
地震震源处，其温度和压力与地壳浅处及地表不同，温、压越高，共轭破裂角越大。
The temperature and pressure at the focus is different from the shallow of the crust and the ground. The higher temperature and pressures, the larger conjugate rupture angle.
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.
但并不是所有的地表断裂都直接与震源的运动相联系，它们也可能是由于地震波造成的次生影响。
However, not all the fault surface and the source directly linked to the campaign, they also may be due to seismic waves caused by secondary effects.
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.
