| Zusammenfassung |
| To realize the deformation behavior around the Caucasus area, a suture zone of
Arabia-Eurasia continental collision, a cooperating project between Taiwan and Georgia has
built up the campaign-mode GPS stations between greater and lesser Caucasus
since 2007, and start to establish 12 Continuously Operating Reference Station
(CORS) collaborated with Institute of earth Science, Ilia State University, Tbilisi,
Georgia and Georisk, Yerevan, Armenia in 2012. The preliminary result shows the
shorten rate reach 4 mm/yr in Javakheti Fault, 6 mm/yr in Lesser Caucasus and
3 mm/yr in greater Caucasus, with respect to station ZECK, located in Eurasia
plate. A 2-D dislocation model is carried out to invert the locked depth and slip rate
along the major N-S trending thrust fault. In addition, we use C-band Envisat radar
images and PS-InSAR technique to analyze the deformation pattern in Javakheti
highland. The average deformation rate is about 5-10 mm/yr along line of sight towards
satellite (LOS), this result infers that the extensional or transtensional deformation is
dominant in Javakheti highland. A significant uplifting is observed in the Ararat basin. |
