“…The horizontal velocities were estimated from displaced alluvial fans and stream channels to be of less than 1 mm/yr (Achmon, 1986) with a left-lateral sense. A sinistral sense of displacement also characterizes some of the earthquake epicentres detected along the CF (Hofstetter et al, 1996). Recent geodetic results based on GPS observations in the same sites show controversial displacement rates and senses, ranging from 3.5 mm/yr dextral (Agmon, 2001), through 1 mm/yr sinistral (Ostrovsky, 2005) to about 4 mm/yr sinistral (Shahar and Even Tzur, 2005).…”

International audienceThe existing knowledge about the recent crustal deformations along the Carmel Fault in Northern Israel which passes the city of Haifa is to a certain degree ambiguous. Depending on geological, geophysical or geodetic sources the movement rates and senses range from 1mm/yr sinistral up to 4mm/yr dextral. In this paper we analyze GPS data from a regional network observed between 1999 and 2009 and derive global and regional velocities for 23 sites along the fault. The regional site velocities were estimated with respect to a local datum that was defined by a stable cluster of sites on one side of the fault and the horizontal velocity field shows deformations of up to 4.5mm/yr dextral. In combination with an S-transformation the site velocities were used to estimate the parameters of a dislocation model based on elastic half space theory. We compare the results with expectations from slip rate analysis of seismicity parameters. In addition the resulting fault slip field is used to derive a fault-related velocity field

“…According to geophysical studies the surrounding area of the CF is a relatively high seismic active region (Hofstetter et al, 1996). Geological studies (Zviely et al, 2009) on sedimentary rocks show maximum vertical offsets of about 0.06 mm/yr in the last 600 thousand years.…”

“…Many authors locate the main Carmel fault onland along the southwestern side of the Yizre'el Valley (through the Jenin region) toward the Fari'a graben (N. Milhan) (Fig. 2;Nur and Ben Avraham, 1978;Hofstetter et al, 1996;Fleischer and Gafsou, 2005;Rotstein et al, 2004). Others locate the main fault somewhere within the Yizre'el Valley downfaulted structure (Garfunkel, 1981;Hatzor and Reches, 1990;Shaliv, 1991).…”

“…In some studies the CGF reaches the end of the continental shelf (Ginzburg et al, 1975;Ben-Avraham and Hall, 1977), whereas in others it continues further into the Levant basin (e.g. Ben-Gai and Ben-Avraham, 1995;Hofstetter et al, 1996). Abdel Aal et al (2000) and Ben-Avraham et al (1988) continue the CGF up to the Latakia Ridge.…”

“…Most of the current seismic activity from these sources has magnitude (M L ) less than 3 and occurs at focal depths of 5 to 25 km. The seismicity exhibits a pronounced clustering in the Dead Sea fault zone and the Carmel Fara fault ( VAN ECK and HOFSTETTER, 1989;HOFSTETTER et al, 1996). Joint focal mechanism analyses carried out on several groups of events along the Dead Sea fault system indicate a north-south strike-slip faulting mechanism ( VAN ECK and HOFSTETTER, 1990).…”

A computerized application of an integrated seismological GIS model is presented. An object oriented approach of the GIS topology is introduced and the special functions and features of this system are described. A network topology was selected to simulate the network characteristics of seismological data management and analysis. Each seismological entity is considered as a graphical data object, which is associated to other objects by predefined relationships. The graphical user interface introduced by GIS enables to handle seismological software routines and data in a more intuitive way. Examples of interactive processing of seismic waveforms for detecting, locating and characterizing seismic events using GIS visualization capabilities are presented. The benefits of this system during a passive seismic survey in the framework of the CTBT are highlighted.
