Erratic rain pattern, topography behind Kerala’s vulnerability to disasters

Hindustan Times  

A day after landslides flattened entire settlements in Kerala’s Wayanad, experts said the monsoon’s changed character due to climate change has made several parts of the country susceptible to climate disasters, and Kerala especially so because of its unique location and topography. The immediate reason for continued heavy rainfall over Kerala in the last few days is an active off-shore trough along Kerala coast with a cyclonic circulation in the lower levels over the South-East Arabian Sea and adjoining Lakshadweep Islands off Kerala coast, India Meteorological Department explained. The monsoon moisture flow moves over hilly regions and gets uplifted, forming multi-cell clouds leading to large amounts of rainfall,” explained Roxy Mathew Koll, climate scientist at Indian Institute of Tropical Meteorology. Human intervention definitely did not cause the landslide but I think the river banks and floodplains along Choolarmala, etc are not suitable for settlements or construction,” added KS Sajin Kumar, Kerala based geologist.
