    en.wikipedia.org/wiki/SEG-Y

    SEG-Y Files are stored in a hierarchical byte-stream format that combines both textual and binary data segments. The following chart shows the byte stream structure of revision 1 (2002), [5] with revision 2 (2017) only adding an optional data trailer for 1 or more 3200-byte records at the end: [6] [7]

    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.

    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.

    An animation detailing how earthquake warning systems work: When P waves are detected, the readings are analyzed immediately, and, if needed, the warning information is distributed to advanced users and cell phones, radio, television, sirens, and PA systems/fire alarm systems before the arrival of S waves.

  9. Endurance time method - Wikipedia

    en.wikipedia.org/wiki/Endurance_time_method

    The basic concepts of the endurance time method were published in 2004. [8] Application in linear seismic analysis appeared in 2007. [2] ET was subsequently extended to nonlinear analysis of single degree of freedom (SDOF) and multi degree of freedom systems. [9]
