A multimodal and multitemporal assessment of mud volcanism in Azerbaijan by drone and remote sensing

Merz, Lena; Huseynova, Ayten; Hilgers, Christoph

Abstract (englisch):
Understanding the impact of mud volcanism and associated hydrocarbon flow towards the surface is critical for safety of drinking water, agriculture and during hydrocarbons exploration. These natural phenomena are abundant in Azerbaijan as well as in other countries. Newest developments in drone-based analytical and mapping technologies, as well as freely available high-resolution satellite data, open new possibilities. The aim of our project is to map and evaluate migration pathways of fluids from the regional scale down to one mud volcano, and to evaluate the environmental impact of natural seepages of hydrocarbons.
The WNW-trending Greater Caucasus fold- and thrust-belt is characterized by S-SSW verging folds and associated thrusts (e.g. Devlin et al., 1999; Saintot et al., 2006). Horizontal tectonic stress is assumed to be oriented c. 30° with c. 10 mm/year movement velocity (Bonini and Mazzini, 2010). Muds and associated fluids migrate from overpressured shales in up to 5 km depth along faults and fracture networks to the surface and generate constant small seeps and degassing of methane (Guliyev, 2006).
We conducted lineament mapping based on ASTER-data and studied their dilation and slip tendency with 3DStress-software. ... mehr
