Hi Tian, in my opinion speed of landslide is an issue for earthquake-induced landslide which is caused by plate movement or volcanic eruption. Geologists are the experts who can advise triggering mechanism of earthquake-induced landslide.

But, the volume of landslide is also important. Usually deep-seated landslides (which is caused ground water rise) triggered by heavy rainfall (during monsoon or long duration) produce larger movement/volume.

Tian-shun Hou According to me the triggering mechanism of high-speed remote landslides can be heavy rainfall.

According to me the triggering mechanism of high-speed remote landslides can be earthquakes, breakthrough of landslide dams, rapid melting of glaciers and other reasons.

A high-speed remote landslide, also known as a "rock avalanche", can be triggered by a number of mechanisms, including earthquakes, heavy rainfall, snowmelt, and human activities such as mining and construction. These triggers can cause instability in the slope, leading to the failure of rocks and soil to slide down the slope at high speeds. The exact triggering mechanism can vary depending on the specific slope and conditions, and it is an active area of research in geology and engineering.

Hello there, there are various triggering factors that have impact on landslide movements. Generally, rainfall and seismicity play key roles.
