Sea-based blowhole Land-based blowhole. In geology, a blowhole or marine geyser is formed as sea caves grow landward and upward into vertical shafts and expose themselves toward the surface, which can result in hydraulic compression of seawater that is released through a port from the top of the blowhole.

A blowhole is a cavity formed when a joint between a sea cave (formed by erosion) and the land surface above the cave becomes enlarged. The sea cave and the land surface become conjoined when the roof of the cave collapses. Blowholes are formed by the process of erosion.
The Pancake Rocks are a heavily eroded limestone formation where the sea bursts through several vertical blowholes during incoming swells, particularly at high tide. The limestone was formed in the Oligocene period (around 22–30 million years old), a period in the geological history of New Zealand where most of the continent of Zealandia was submerged beneath shallow seas.

Blowhole may refer to: Blowhole (anatomy), the hole at the top of a whale's or other cetacean's head; Blowhole (geology), a hole at the inland end of a sea cave
The blowhole is most active when the tide is high and the winds are strong, [3] and it can shoot sea spray up to thirty feet high in the air. [ 4 ] Hālona Point is a tourist spot, with visitors coming for the scenery, the beach at the cove, and in the winter as a spot to go to see humpback whales or Honu turtles (Hawaiian Green Sea Turtles).
Forget drones through fireworks, this is way more beautiful.
Watermelons can offer a nice explosion of flavor in your mouth, but they shouldn’t be spontaneously combusting. Oddly enough, that’s exactly what some fans of the popular fruit are worried ...
In cetology, the study of whales and other cetaceans, a blowhole is the hole (or spiracle) at the top of the head through which the animal breathes air. In baleen whales , these are in pairs. It is homologous with the nostril of other mammals , and evolved via gradual movement of the nostrils to the top of the head. [ 1 ]
