smc format

Post by sanami »

Hi Seismosoft.
Could you please guide me about accelerograms with sac format? I don't know how can I calculate delta-t and scale factor for importing this format to seismosignal.
Is this format type suitable for dynamic time history similar to PEER format (*.dat)?

Hello sanami,
Unfortunately, we are not aware of the details of the SAC format.
SeismoSignal has a number of settings for reading acceleration values from text files. Refer to the program's help system for details and you will probably be able to open and read the files correctly.

SMC file format details may be found at the USGS web site.

https://escweb.wr.usgs.gov/nsmp-data/smcfmt.html

There is a free utility available at the COSMOS web site to convert smc files to Excel and various other formats.

http://www.cosmos-eq.org/VDC/index.html

In my experience with smc files, I have found it best to convert to Excel using the COSMOS utility, then copy and paste the time series into a text file for opening in SeismoSoft programs. Having said that, if you study carefully the data fields in the smc format info, you may well be able to directly use the smc file in Seismo software.

Best of luck.
