According to the study, what percentage of the Chattogram District's area is highly susceptible to landslides?
|
9-12% |
|
The LSMs showed that almost 9–12 % of areas of the Chattogram district are highly susceptible to landslides. The highly susceptible zones cover the Chattogram district's hill ranges where active morphological processes (erosion and denudation) are dominant. |

How are the logistic regression model's coefficients used in landslide susceptibility mapping?
|
To assess the environmental impact |
|
Because landslides are a natural disaster that is difficult to prevent, we can reduce the risk factors and damage if we are well prepared and vigilant. |
