The amazing Blowhole in the world occurs when the tide fills underwater caverns with seawater. The caverns are caused by a geological process of shoreline erosion. This can happen through ‘hydraulic action’ where the waves cause pressure on the air pockets within the little cracks in the cliff, widening them further; ‘abrasion’ caused by the waves bashing rocks, pebbles, sand and other material into the cliff; chemical weathering caused by the acid content in seawater, especially lethal to rock compositions such as limestone; and ‘attrition’, a sandpapering effect caused by small loose circular rock debris. If the caverns have an aboveground opening; the pressure causes the water to push out periodically in a fountain, or ‘blow’. The timing and height of the water fountains from these blowholes are dependent on the tides and wave formations. This is how Hummanaya blow makes.
The blowhole itself is a natural crack in the rocks, and when the wind blows in the right direction the water shoots up the cliff and into the air the water shouted up above the cliffs in the monsoon seasons more than 30 M.
