The 5 September 2018 (UTC time) Mw6.6 earthquake of Tomakomai, Japan has triggered about 10,000 landslides with high density, causing widespread concern. We attempted to establish a detailed inventory this slope failure and use proper methods assess landslide susceptibility in the entire affected area. To end we applied logistic regression (LR) support vector machine (SVM) for study. Based on high-resolution (3 m) optical satellite images (planet image) before after earthquake, delineated...
This study constructs a preliminary inventory of landslides triggered by the MS 6.8 Luding earthquake based on field investigation and human-computer interaction visual interpretation optical satellite images. The results show that this at least 5 007 landslides, with total landslide area 17.36 km2, which smallest is 65 m2 largest reaches 120 747 m2, an average about 3 500 m2. obtained are concentrated in IX intensity zone northeast side seismogenic fault, density point 13.8%, 35.73...
Abstract Background On September 5, 2022, an Ms 6.8 earthquake occurred in Luding County, Ganzi Tibetan Autonomous Prefecture, Sichuan, China. The casualties and economic losses caused by the are huge. Most of landslides triggered this small medium-sized rock collapses destructive debris flows, with a number large-scale landslides. Results There 5007 coseismic VII-degree area above, total 17.36 km 2 . generally distributed along NW-SE direction. highest landslide density is 13.8%, point...
On August 8, 2017, a magnitude Mw6.5 (Ms7.0) earthquake occurred in Jiuzhaigou County, Aba Prefecture, the northern part of Sichuan Province, China, with focal depth 20 km and an epicenter located at (33.2°N, 103.8°E). Due to significant earthquake, large number coseismic landslides were triggered. Despite previous research conducted by experts on caused actual has been severely underestimated previously published papers. Through field surveys visual interpretation high-resolution remote...
Abstract The Qinling Mountains in China frequently experience geological disasters, with large‐scale landslides being particularly prominent, causing severe economic losses to the local area. To gain a comprehensive understanding of disaters distribution region, we conducted extensive research on entire Mountains, covering an area approximately 380,000 km 2 . By employing methods such as literature review, data collection, and interpretation remote sensing images, have successfully created...
Rainfall-induced landslides pose a significant threat to the lives and property of residents in southeast mountainous area. From 5 10 May 2016, Sanming City Fujian Province, China, experienced heavy rainfall event that caused massive landslides, leading loss life property. Using high-resolution satellite imagery, we created detailed inventory triggered by this event, which totaled 2665 across an area 3700 km2. The majority were small-scale, shallow elongated, with dominant distribution Xiaqu...
The 2013 heavy rainfall event (from June to July) in the Tianshui area triggered most serious rainfall-induced group-occurring landslides since 1984, causing extensive casualties and economic losses. To better understand characteristics triggers of these loess landslides, we conducted a detailed analysis relevant influencing factors. Based on landslide database obtained using visual interpretation remote sensing images before after rainfall, correlation between occurrence different factors...
After a major earthquake, the rapid identification and mapping of co-seismic landslides in whole affected area is great significance for emergency rescue loss assessment seismic hazards. In recent years, researchers have achieved good results research on small scale single environment characteristics this issue. However, earthquake-affected with large complex environments, correct rate extracting remains low, there no ideal method to solve problem. paper, Planet Satellite images spatial...
Rainfall-induced landslides pose a significant threat to the lives and property of residents in southeast mountainous hilly area; hence, characterizing distribution pattern effective susceptibility mapping for rainfall-induced are regarded as important necessary measures remediate damage loss resulting from landslides. From 10 June 2019 13 2019, continuous heavy rainfall occurred Longchuan County, Guangdong Province; this event triggered extensive landslide disasters villages County. Based...
Rainfall-induced landslides pose a significant threat to human life, destroy highways and railways, cause farmland degradation in the Loess Plateau. From 19 June 2013 26 July 2013, continuous heavy rainfall events occurred Tianshui area, Gansu Province. This strong process included four short-term serious long-term intermittent rainfall, triggering many shallow loess landslides. To improve our understanding of this as mechanism landslides, we conducted physical-based spatiotemporal...
