| Abstract: | The Steim2 compression algorithm,based on SEED volume format,is a widely-used algorithm in the transmission and local storage of seismic data.However,it has obvious advantages and disadvantages.One advantage is that it is an algorithm specially in accordance with the characteristics of long period of seismic quiescence and long intervals between earthquakes,suggesting its unique feature.One disadvantage is that it is useless during seismically active period or during the time when earhtquakes strike unexpec... |
