It covers a geographic area of 38,863 km2. On the west is the Arabian sea along its 587.8 km long coast line and in the eastern side of the State lie the mountains of the Western Ghats. Forests of the Western Ghats played a major role in providing biomass for diverse agricultural practices. However, land-use changes, particularly conversion of natural forest for other uses, impacted ecological functions of the forest ecosystem, and brought about drastic changes in the soil chemistry, setting in motion to the process of forest degradation and affecting Kerala’s life line of forty-four rivers.

In addition to property damage, heavy rainfall (36% above normal) and multiple landslides (4728) killed 48 people in 2018. This tendency continued throughout the monsoon seasons of 2019, 2020, and 2021, resulting in the deaths of over 100 people. Anomalous precipitation is ascribed to the frequent development of low-pressure in the surrounding oceans. Using ground real data and satellite imagery, we evaluated the features of three large landslides in the state of Kerala, which occurred during the monsoon season of 2021. Our investigation found that the Kokkayar landslide was triggered by anthropogenic-related agricultural activities, the Plappally landslide by geomorphic and tectonic processes as well as human involvement, and the Kavali landslide by forest fragmentation with dense vegetation on thin soil. The triggering mechanism for all three of these landslides, however, is the intense rainfall of 266 mm in less than 24 h. Thus, an accurate and precise forecast of rainfall can be used to define a threshold for an early warning, which will be vital for saving lives.
