Hi Badal

I have heard of landslide hazard map. But, not the dynamic one. If it is dynamic, I believe that it should be changing with time and reflecting the current hazards.

Best regards

Hi Sinnappoo (Ravi) Ravindran,

Thank you for your answer

....Hello M. Alvioli,

Thank you so much for the description. Yes, it does answer my question. I had heard from few professors regarding "Dynamic Landslide Hazard Mapping". I thought the theory behind this is to include some time-dependent factors and prepare the model. Your answer made it clear.

Thanks

Hi Badal.

Dr M. Alvioli addressed the question very well. However, I have a few comments in addition.

In my perspective, I think, in addition to the integration of temporal factors in landslides susceptibility assessment e.g. rainfall (the most dominant one) or some other fluctuating variables with time, and assessing their scenarios makes a dynamic hazard map, however, at present we also need to consider about the variation with "strength", in case of earthquakes. For example, most earthquakes triggered landslide susceptibility models suffer the lack of scenarios for variation of ground accelerations due to different magnitudes or rupture nature and other dynamic earthquake parameters, while their further links to the variations of basic landslide susceptibility parameters are still there. So, in my perspective, the dynamic landslide susceptibility maps involves a temporal variation of parameters e.g. rainfall, groundwater levels, etc. while it can also involve the driving force variation e.g. ground acceleration scenarios, fault rupture scenarios, etc .in the case of earthquake-triggered dynamic landslides. However, much work still needs to be done in the latter kind. From a wide perspective, however, the latter part can also be a temporal phenomenon but the present research has still a way to go further.

Dynamic landslides here could be related to areas with intensive rainfall all over the year and a higher probability of landslides occurence ..these area usually in tropical region such as Malaysia and Southeast Asia countries where the major factor of landslides occurence is rainfall

Thank you all for your answers. They are really helpful .

What about the use of geospatial technology to plot the relative slope of geographic areas using lidar or similar techniques to map areas most susceptible to landslides, particularly after widespread ground cover fires using aircraft or drones equipped with lidar equipment? Dan
