Seasonal Slow Landslide Displacement Is Accommodated by mm‐Scale Stick‐Slip Events

چکیده
Like faults, landslides can slip slowly for decades or accelerate catastrophically. However, whereas experimentally derived friction laws provide mechanistically based explanations similarly diverse behavior on little monitoring exists over the temporal and spatial scales required to more clearly illuminate mechanics of landslide friction. Here we show that displacement an active slow is accommodated primarily through mm-scale stick-slip events recur timescales minutes hours asperities are small (<100 m) relative landslide. The frequency tracks both velocity pore fluid pressure. nature demonstrates by itself governed, at least in part, velocity-weakening frictional asperities. This observation, combination with sensitivity pressure scale asperities, suggests similarities between episodic along faults.

Study on displacement prediction of landslide based on neural network
In recent years, the economic losses caused by landslides were as high as several billion dollars. Therefore, the study of landslide risk has become a hot topic today. Landslide displacement prediction is a highly nonlinear and extremely complex issue. In most cases, it is difficult to use mathematical models to describe the process clearly. Data mining technology, which uncovers the hidden dat...
متن کاملLandslide Displacement Monitoring by a Fully Polarimetric SAR Offset Tracking Method
Landslide monitoring is important for geological disaster prevention, where Synthetic Aperture Radar (SAR) images have been widely used. Compared with the Interferometric SAR (InSAR) technique, intensity-based offset tracking methods (e.g., Normalized Cross-Correlation method) can overcome the limitation of InSAR’s maximum detectable displacement. The normalized cross-correlation (NCC) method, ...
