Beach Type

Honokalani Black Sand Beach is closer to the plate boundary and close to tectonic activity. Because of this, the beach is an active coast, meaning it is the leading edge of the continent where it's crashing into an oceanic plate.

It is a primary coast, meaning it is a younger coast created by land processes. It is classified as a primary coast because its features are created by volcanic forces.

The black sand beach is an emergent coast, meaning it has been rising relative to sea level since its existence.

Sand & Origin

The Honokalani Black Sand Beach is covered in black sand. The sand comes from Basalt (igneous rock) fragments. When the volcanoes erupted and the lava contacted water, it cooled rapidly and shattered into sand and fragmented debris.

Beach Features

The Honokalani Black Sand Beach is famous for its beautiful black sand, tidal caves, and its native plants. The beach is open to the ocean with no outside reef to break the force of waves and currents, making the forces of the water very strong. This makes the beaches dangerous to swim at, so swimming at the Honokalani Beach should be avoided. The black sand beaches are also known for their rugged, irregular topography as a result of the beach being formed by volcanic forces.
