In Kerala’s Wayanad, 200 people have died in major landslides triggered by heavy rain on Tuesday (July 30) and hundreds are still trapped under the debris, raising fears of more fatalities.

During the last decade, Kerala has suffered the most due to landslides in India, according to data released by the Union government.

These landslide data were collected by GSI through onsite field investigations under the Post-Disaster Studies programme taken up annually by GSI in all the landslide-prone states and Union territories as per GSI’s Standard Operating Procedure, mainly in response to the requests received from the concerned state governments.

According to the Union government, out of the 3,782 major landslide incidences, Kerala witnessed the highest with 2,239 landslides during the period 2015-2022.

Field validation

For all these landslides, during field validation, GSI collected vital preliminary geoparametric attributes for each of the landslides, including studying its impacts, future vulnerability, and indicating the requirements for future detailed geoscientific investigations, if any. The Centre said all the data are also used for updating GSI’s existing national landslide inventory.

Jitendra Singh said that avalanches and landslides are natural phenomena that cannot be prevented. However, early warnings and forecasts for rainfall and snowfall are being issued by various institutions under the Ministry of Earth Sciences and the Ministry of Defence.
