Kaimū[1] was a small town in the Puna District on Island of Hawaiʻi that was completely destroyed by an eruptive flow of lava from the Kūpaʻianahā vent of the Kīlauea volcano in 1990.

[3] The lava flow that destroyed Kaimū and nearby Kalapana erupted from the southeast rift zone of Kīlauea.

The bay was world-famous for its black sand beach which was surrounded by shady palm trees.

A large section of State Route 130 (Kaimu-Chain of Craters Road) was also covered by the lava.

There is also the New Beach, black sand like the old, where locals and visitors are bringing sprouted coconuts and planting them to restore the lost trees.
