1 ReWARD (Refraction/Wide-Angle Reflection Database): The Calabrian Arc subset The ReWARD Working Group The ReWARD Working Group GNGTS-22° Convegno Nazionale Roma, novembre 2003 Istituto Nazionale di GEOFISICA e VULCANOLOGIA Sezione di Sismologia Applicata-Milano M. Maistrello, G. Musacchio, A. Gassi: INGV – MI (Milano) C. Marcocci: INGV-CNT (Roma) G. Gaudiosi: INGV-OV (Napoli) I. Guerra: Università di Cosenza

2 From the old DOL project: From the old DOL project: more than 200 profiles (> km) more than SEALAND data The Project Structured archive of Italian controlled source seismological data (Refraction and Wide Angle Reflection data only) Structured archive of Italian controlled source seismological data (Refraction and Wide Angle Reflection data only)

3 The DATA Old analog data (60s to 90s) have been digitized Old analog data (60s to 90s) have been digitized Accessory data Accessory data Georeferenced maps Georeferenced maps Cross sections (bitmaps) Cross sections (bitmaps) Models Models Bibliography Bibliography High resolution wide-angle digital data (SEALAND) High resolution wide-angle digital data (SEALAND)
