New Zealand geyser erupts, shooting water into the air
A geyser shot water high into the air from New Zealand's Lake Rotorua early on Monday morning, panicking some local residents.
The eruptions at about 04:30 (15:30 GMT Sunday) woke people living in Ohinemutu, in New Zealand's North Island.
Reports said the water reached heights of between seven and 30m (23-98ft).
The area is known for geothermal activity, but the location and size of the geyser is unusually large.
What happened?
The Rotorua Lakes Council said a build-up of steam and pressure caused the eruption, according to Radio New Zealand.
Locals reported hearing a series of loud thuds, followed by a spraying sound.
