The Back-projection of teleseismic waves has been proven efficient at resolving rupture durations and source extents of large seismic sources. It requires no prior knowledge of fault geometry, fault dimension, or focal mechanism. In addition, this observation-driven method takes advantage of the entire P wavetrain, and the calculation of synthetic seismograms is not needed.

The purpose of the manual is to roughly show how our Back-projection procedure works. In particular, the whole programs are written or supported by these tools: SAC, Fortran Language, GMT 4 and Linux system.

Here, the back-projection program is divided into a few parts. In every part, we mainly narrate how to run our program step by step, and show some suggestive codes. Please look over full scripts and relative files by clicking here. Please contact me to look over full scripts and relative files. In scripts, we add annotations in detail. In some parts, you can replace our scripts with your method flexibly.

Outline

Example

In the manual, we take the 2011/03/11 Tohoku great earthquake as an example, using seismic data recorded in Unite State array, to introduce our method in detail.

Besides, I will analyze most large earthquakes using the method and upload results here, and you also can visit real-time back-projection website results maintained by Dun Wang.
