The blowhole has promoted tourism in the area, and a viewing platform has been erected for the tourists who visit the region. The blowhole generates a spectacular water fountain in intervals of several minutes which can shoot up to 98 feet depending on sea conditions. The Hummanaya Blowhole is the world’s second largest of this landform, and it is located in Sri Lanka. This blowhole is notably known for causing several deaths through suction in the returning water or falling into the hole. The blowhole is located near Poelua Bay, and its name translates to “the leaning” in the local language. Water jets from this blowhole can reach a height of 100 feet. The world’s largest blowhole is found in Nakelele Point in Hawaii. The jet sprays often create a loud noise as they gush out. Water enters these crevices when there are powerful waves in the sea, and it is released in the form of jet sprays through the blowhole. Such areas have been mapped out as lying along fault lines and on islands. Where Are Blowholes Located?īlowholes are mainly located in regions with crevices in the coastal rocks. The landform manifests as a crack or fissure once formed. A blowhole can also be formed when lava flows make openings in the ground which extend towards the sea. Hydraulic pressure, built up by a succession of waves, eventually carves out a hole at the top of the cave to create an opening for water pressure to be expelled as a jet of spray. These caves are regularly exposed to waves. Parts of weakness in the cliffs are weathered out by wave action thereby forming large cavities known as sea caves. Sea Caves are a common feature along the coasts and are formed through mechanical erosion of cliffs. A blowhole is characterized by an opening on the ground and a connection to an opening which interacts with the sea, mostly a cave. The activities of the blowhole depend on the sea conditions as well as its geometry and that of the sea cave. ![]() ![]() Water often gushes out at the top part of the landform when waves move to the sea cave with significant force. When sea caves grow towards the land and upwards creating a vertical shaft that exposed on the surface, it results in a blowhole. Coastal Landforms: What Is A Blowhole?
