Around 51 landslides were reported in the year 2018 and 2019. Heavy rains for two weeks before the July 30 incident are also a reason. Although rain cannot be considered the main reason, but yes, there is definitely an underlying reason. But the real cause of the landslide came to light in a report by the Kerala Forest Research Institute (KFRI).
Landslide caused by heavy rain
It rained in Wayanad, Kerala on the midnight of 30th July. Heavy rains caused landslides and the landslides created a horrific scene of devastation. More than 300 people lost their lives in this incident. Many families have lost their loved ones in this incident. Landslides are not a big deal in the hilly areas of Wayanad district. Similar reports of landslides have been coming from this area before as well. However, the death toll in these incidents was much less than the recent incident. In such a situation, the question is why is this southern district getting affected by landslides? By understanding this, we will also know what are the other reasons for landslides.
It rained continuously for two weeks before the landslide
About 51 landslides were reported in the year 2018 and 2019. Heavy rains for two weeks before the incident on July 30 are also a reason. However, rainfall alone cannot be considered the main reason. But yes, there is definitely an underlying reason. But a report by the Kerala Forest Research Institute (KFRI) states that the real cause of the landslide was digging in the hills. The reason for this is that digging mostly takes place anywhere. Such incidents keep coming up there every day.
Excavations in the mountains
In hilly areas, explosions are used to carve hills or break mountains. This type of explosion produces a type of vibration. This vibration causes the mountain to collapse. But the effect of earthquake tremors is not limited to mountains only. Its effect is felt over an area of several kilometers. Due to a powerful explosion, the earth shakes and then a slight crack appears. After this, if there is heavy rain somewhere, water enters these cracks and a big flood occurs.
rainfall pattern is changing
The incidence of landslides is increasing continuously in God's kingdom Kerala. Apart from the digging of mountains, there are many other reasons for this. One reason for this is deforestation. The state of Kerala is known for its tea cultivation since the last century. But in recent times, forests are also being cut down rapidly. Due to which the environment of the state has changed. And due to this the pattern of rain has also changed. Due to which the incidence of landslides is increasing in the sloping areas.
Flooding occurs quickly in loose soil
This district is located on the slope of the Western Ghats. The slope is very steep. There are many valleys and hills in these areas. Due to which the possibility of landslides also increases in such areas. Wayanad receives heavy rainfall during the monsoon season. Sometimes it rains more than 2000 mm here. Due to which the soil there becomes saturated. Due to which the soil starts eroding. Most of the soil in the district is laterite soil. This means very weak and eroded soil. When it is saturated with rain, its weight increases. But with the increase in weight, the strength of this soil decreases, which increases the possibility of landslide incidents.
