Abstract Geological structures identification using conventional optical remote sensing encountered some problems due to atmospheric and surface conditions. Therefore, we exploited the Synthetic Aperture Radar (SAR) in Ascending Descending orbits characterize lineaments related geological structures. We have analyzed two images from Phased Array type L-band (PALSAR) onboard Advanced Land Observ...

Chiang Khong Basin (CKB) is a northeast-southwest active basin in Rai province, northern Thailand. The bounded to the east by numerous fault segments of Mae Ing Fault Zone (MIFZ), where they have triggered several previous earthquakes and vicinities. Although slip MIFZ has some earthquakes, deformation landscape affected tectonic processes mainly unknown. According uniform lithologic climatic c...

Abstract Yogyakarta has experienced two devastating earthquake disasters: May 26, 2006, Mw6.4, and the penultimate event, June 10, 1867 Mw7.7. The active fault that is thought to be responsible for events Opak Fault. However, Fault still not been thoroughly well mapped yet. lack of a high-resolution image, dense vegetation cover, high sediment flux from Merapi volcano, human activities eroding ...

The 2020 Elliot Creek landslide-tsunami-flood cascade originated from an 18.3 Mm 3 rock slope failure in quartz diorite bedrock a valley undergoing rapid glacial retreat. We used airborne LiDAR and optical imagery to characterize the its surroundings. Using LiDAR, we determined that two rockslides (2020 older undated one) occurred on this shared common basal rupture surface. mapped main sets of...

Extraction and interpretation of tectonic lineaments is one of the routines for mapping large areas using remote sensing data. However, this is a subjective and time-consuming process. It is difficult to choose an optimal lineament extraction method in order to reduce subjectivity and obtain vectors similar to what an analyst would manually extract. The objective of this study is the implementa...

Studying hydrothermal systems in basement environments requires knowledge of fault and fracture network distributions. This study addresses this through multi-scale structural analysis the Têt its surrounding (Eastern Pyrénées) using remote sensing field data. aims to achieve through: 1) precisely mapping describing brittle network, 2) analysing distribution lineaments outcrop-scale fractures r...
