On January 30, 1901, the world’s tallest geyser was identified. Waimangu was described by Dr. Humphrey Haines, and located on the North Island of New Zealand. Eruptions from this geyser, active from 1900 to 1904, could reach 488 meters (1,600 feet) in the air. That is 10 times as high as Yellowstone National Park’s Old Faithful. It is also higher than the Empire State Building.
A geyser is an underground hot spring that periodically erupts through the surface in a spray of hot water and steam. The eruption is caused by hot underground magma, or molten rock, heating the spring’s water. Waimangu, which means “black waters” in the native Maori language, was named for the chunks of black rock it hurled into the air with each eruption.
