Earthquakes are a terrible natural disaster that can cause massive losses and damages. They happen when the ground shakes violently due to sudden movements of the earth's crust. One of the major reasons that can trigger earthquakes is the lack of water in the soil, which makes it dry and hot. And the soil gets dry due to Ground Water Depletion. Ground water gets depleted due to over exploitation of ground water resources leading to increase in the Earth crust temperature.
Ground water recharging - Most Countries worldwide face this problem of water scarcity and wastage. They do not have enough sources of water to meet their needs, and water usage is not monitored and not consumed wisely to recycle the water. Dumping waste water (Grey water and black water) into sewers, which take it away from the land.
Urbanisation and construction - In order to build houses, roads, offices and other structures using construction materials that do not allow water seepage in the soil / ground. This creates a situation where the top layer of the soil becomes dry and hard, and the lower layers become hot and unstable. This leads to gradual extinction of under ground creatures which feed on the water received from the top layer.
One of the ways to prevent this problem is to practice rainwater harvesting and seepage. This means collecting rainwater and storing it for later use, or letting it soak into the ground through natural or artificial methods. This can help replenish the water in the soil, and keep it cool and moist. This can reduce the chances of earthquakes, and also improve the ground water levels, help save water for other purposes.
