offset is the distance between the shot_point and the observing point.
It is a type of Radon transformed data. In tau-p domain it is easy to delineate the events form the multiples and hence its is easy to identify and remove the multiples. This data again transformed back to X-T domain.

Seismic data is acquired to image and understand subsurface geological structures and properties. It helps in locating oil and gas reservoirs, assessing potential drilling sites, and aiding in various geophysical and geological studies.
Seismic stratigraphy is a geologic approach to the interpretation of seismic data, allowing their application based on physical stratigraphy. Primary seismic reflections parallel the surface and nonconforming surface of the strata.
A seismic trace is a graphical representation of seismic data collected during seismic surveying. It shows how the amplitude of seismic waves changes over time and can be used to identify subsurface structures like rock layers or hydrocarbon reservoirs. Seismic traces are essential in geophysics for interpreting subsurface geology.

To calculate a rolling offset, you first define the time period over which you want to analyze the data, such as daily or weekly. Then, you shift the data series by a specified number of periods (the offset) while maintaining the alignment with the original series. This is often done using statistical or data analysis software, where functions like shift() in Python's pandas library can be employed. Finally, you can perform calculations, such as averaging or summing, on the shifted data to derive insights from the rolling offset.

A seismograph records seismic waves generated by earthquakes, explosions, or human activities. It captures data such as the time, duration, and amplitude of these seismic waves to provide information about the location and magnitude of the seismic event.

How seismic waves travel.:)
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
The seismic stations record data on the other side of the planet by disturbing the timing of the electrical current. The horizontal magnetic directions are hit by a shock wave, allowing information about the area closer to the earthquake. The seismologists average their data and do final calculations. Within two weeks, they have their data.
