This image shows the byte stream structure of a SEG-Y file, with rev 1 Extended Textual File Header records. Since the first SEG-Y standard was published, many companies dealing with seismic data have produced variants of the SEG-Y standard which have run contrary to the aims of defining a standard for universal interchange, thus generally causing confusion and delay when data received by a ...

The main scientific goal of the centre is the definitive compilation of earthquake information and the readings on which they are based. Collection of reports of earthquake effects is also an important part of its operation and the Centre recomputes the location and occurrence time of earthquakes worldwide, making use of all available information.
For land acquisition, different types of sources may be used depending on the acquisition settings. Explosive sources such as dynamite are the preferred seismic sources in rough terrains, in areas with high topographic variability or in environmentally sensitive areas e.g. marshes, farming fields, mountainous regions etc. [4] Such type of sources needs to be buried (coupled) into the ground in ...
They also contain important information on ground conditions at particular locations, the underlying geology, radiation pattern of the seismic waves, and the response of different types of buildings. They form an important part of the macroseismic approach, i.e. that part of seismology dealing with noninstrumental data.
