Blowhole (geology)

They are found at intersecting faults and on the windward sides of a coastline where they receive higher wave energy from the open ocean.

The arrangement, angle and size of these three features determine the force of the air to water ratio that is ejected from the port.

Strong reverse draughts in response to pressure changes in a connecting littoral cave can send wind speeds upwards of 70 km/h.

The main factors that contribute to littoral caves formation are wave dynamics and the parent material’s rock property.

[9] La Bufadora is a large example of a blowhole located in the Punta Banda Peninsula of Baja California, Mexico.

It consists of a littoral cave with a thin opening that has a recurrence eruption interval of 13 -17 seconds, ejecting water up to 100 ft. above sea level.
