Kīlauea is an active volcano in the Hawaiian Islands, one of five shield volcanoes that together form the Island of Hawaiʻi. In Hawaiian, the word kīlauea means "spewing" or "much spreading", in reference to the mountain's frequent outpouring of lava. Lava has been issuing continuously at Puʻu ʻŌʻō since January 1983. In 1998 Kīlauea was said to be the most active volcano on the Earth, an invaluable resource for volcanologists, and was said to be the planet's most visited active volcano. The volume of erupted material could pave a road across the world 3 times. Lava less than 1000 years old covers 90% of Kilauea.

Kīlauea is the most recent of a series of volcanoes that have created the Hawaiʻian Archipelago, as the Pacific Plate has moved and is moving over the Hawaiʻi hotspot. An eruption that started in 1983 is ongoing. These eruptions occur in the Puʻu ʻŌʻō vent. Thirty-three eruptions have taken place since 1952 not including the current episode.

In local belief the volcano is the home of the Hawaiʻian goddess of volcanoes, Pele. Legend says that eruptions take place whenever the goddess is angry. These concepts are included in tribal chants practiced by residents of the region.

基拉韋厄火山(Kīlauea)是夏威夷島上的五個盾形火山(Shield volcano)之一。是目前世界上觀光客流量最大的火山,也是最活躍的火山。根據統計,在20世紀內,該火山就爆發了45次。

創造夏威夷群島的一連串火山中,基拉韋厄是最新的一座,太平洋板塊也朝向夏威夷熱點移動。 基拉韋厄的意思是“噴出”或“傳播”,即頻繁源源不斷的熔岩。自1952年以來該火山爆發了33次,1983年的爆發至今未停,其熔岩一直發出不斷流出。 在1998年,基拉韋厄據說是地球上最活躍的火山及寶貴的火山研究資源。該爆發的熔岩可以鋪世界各地的道路3倍。少於1000年歷史的熔岩涵蓋90%的基拉韋厄。

當地人相信火山是夏威夷火山貝利女神的家,而其之所以爆發是由於女神發怒。
