(1) Karawwa is one of the main areas where gem mining taken place. Most of the areas in Kahawatta town are damaged by gem mining. http://www.srilankagemautho.com ] } Because of the underground holes dug for gem mining the area is dangerous. (2) One of the buildings of Kahawatta base hospital has already been submerged and out of use. The area is often suffered by land slidings which may also be as a result of this underground cavities. Gem miners dig a basic pit of 10 to 15 feet in diameter until they find the strips of "illam"( the special stratum of soil, in which precious stones are liable to be found).As that is a stratum it exists horizontally, hence miners have to dig borrows called "dona" horizontally. After all the illams have been taken off the mine is refilled with soil, but donas remain seme.Those donas make the area dangerous.
