Sumatra Data Now Available

Following the magnitude 9.0 event on Dec. 26, 2004, many of the SG groups in GGP are making available files for the months of December 2004 and January 2005 on this website.

 

The data are in two formats, 1 minute data and second data, each in separate directories. All files have headers that contain the metadata (including station latitude, longitude, and instrument calibration factors for gravity and pressure).

*dd contains either a single day of the month (e.g. 05), or is set to 00 if the whole month is in the file

Note there is no repair code for second data (it is implicitly always 00). All second data files are zipped.

 

Log Files

Some stations report log files (*.log) indicating events at the station that may show up in the data. These are put in the 1 minute directory.

*stations such as WE have a dual sphere sensor, separated vertically by several cm. Each sensor generates an independent data series identified by a letter and a number, e.g. W1 for the lower sensor and W2 for the upper. 

For most stations, only 1 sensor series is available

**no pressure included in second data
