Excess pore pressure under seismic loadings has always been a main concern in geotechnical engineering practices. Undergoing the phenomenon in a soil can cause the effective stress and hence the shear strength of the soil to decrease considerably and large deformations happen in the area. Generally, increasing the pore pressure occurs under the undrained condition. If it can be formed the drain...

The Ms 8.0 Wenchuan earthquake, occurred on 12 May 2008 in Sichuan Province, caused enormous property damages and human casualties. Right now, the secondary disasters caused by strong earthquake, especially landslides, have drawn much attention in the affected area. For this reason, it is necessary to research on susceptibility assessment in Wenchuan which is helpful to decrease landslide damag...

Windstorms can cause significant damage to non-engineered structure and infrastructure due the lack of consideration wind force in design construction. Historical windstorm events reflect that is different than most other dynamic forces such as earthquakes, floods, tsunamis, landslides. Bhutan frequently observes major structures infrastructures. Between April 2008 May 2021, 51 were recorded Bh...

On 8 August 2009, the extreme rainfall of Typhoon Morakot triggered enormous landslides in mountainous regions of southern Taiwan, causing catastrophic infrastructure and property damages and human casualties. A comprehensive evaluation of the landslides is essential for the post-disaster reconstruction and should be helpful for future hazard mitigation. This paper presents a systematic approac...

Debris flows are unpredictable phenomena, listed among the hugest natural hazards, since they can cause important damages to humans and structures. Rainfall trigger this type of movements, as it provokes pore water pressure increasing, so soil strength reduction. The phenomenon modelling is a key aspect predict prevent damages. This article shows an approach for triggering runout analysis: stud...

Landslides cause damages and affect victims worldwide, but landslide information is lacking. Even large events may not leave records when they happen in remote areas or simply do not impact with vulnerable elements. This paper proposes a procedure to measure spatial autocorrelation changes induced by event landslides in a multi-temporal series of synthetic aperture radar (SAR) intensity Sentine...

Background: The 2008 Wenchuan earthquake triggered many rapid and long runout landslides, which directly caused great loss of property and human lives and were responsible for a large percentage of total damages caused by the earthquake. It is very important for the purposes of landslide disaster prevention and mitigation to understand the earthquake triggered mechanism of initiation and motion...

distinguishing the susceptible areas to landslide using different landslide susceptibility mapping (lsm) models is one of the primitive and basic works to reduce probable damages and reduce risk. the main purpose of this research is the efficiency evaluation of four methods including information value (winf), valuing area accumulation (wa), analytical hierarchy process (ahp), kopta-joshi propos...
