Turn the Eldest Seismograms into the
Electronic Original Ones

Teseo² is a software tool for quick and accurate digitization of seismogram traces from raster files.

This is the official web site of the Teseo², and contains information about downloading, installing, using, and enhancing it. Teseo² is developed in respect to the "Open-Source" philosophy and it is freely distributed under GPL license. It is cross-platform and the sources, the binaries for Linux, Windows and Mac OS X are periodically provided by the web site http://teseo.rm.ingv.it/pub/teseo/ (the current stable version is 2.0.16).

Teseo² is a plug-in for GIMP. The GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages.

Teseo² is part of Sismos project at Istituto Nazionale di Geofisica e Vulcanologia (Italy)

Teseo 2.0.7 beta release 2005-09-19

Beta version 2.0.7 of Teseo² is now officially released. It will be presented at the 1st Workshop on the Digital Vectorization of Historical Seismograms and it is available from http://teseo.rm.ingv.it/pub/teseo.

1st Workshop on the Digital Vectorization of Historical Seismograms 2005-06-20

20-23 September, 2005 - Grottaminarda (AV), Italy

Historical seismograms vectorization is of primary importance for the reanalysis of past earthquakes using modern approaches. This is important in order to refine earthquake size and mechanism and, in general, for the reappraisal of seismic hazard.

In the past years, INGV-Sismos personnel has developed the Teseo² software for seismogram vectorization (Pintore et al, in press). Recently, a new version of the software named Teseo², has been developed. Teseo² has been found very effective in performing vectorization from raster, high-resolution, seismogram records images. In addition, this new version is available on a variety of operating system platforms (Unix-like, Mac OS X and Windows ). Teseo² is an open source development project.

The aim of this workshop is to introduce the participants to the use of Teseo² for seismogram vectorization. This effort is integral part of the "EuroSeismos project" supported by the European Seismological Commission working group on "History and Data of Instrumental Seismology".

The participants that would like to bring their own record raster images are recommended to contact the organizers.
