Hawaii Volcanoes National Park

only once every eleven months.

The Hawaii Volcanoes National Park lies to the south-east of the Island of Hawaii and was founded in 1916. It includes a large part of Mauna Loa, all of Kilauea, including its eastern and southern sides, as well as the Puna Coast - in all, a considerable area of 21sq.miles/54sq.km.

The most accessible part of the national park is the Kilauea Caldera region which is signposted off road 11 when traveling from either Hona or Hilo.

The last violent eruptions of the Kilauea crater occurred in 1790 and 1924, since when it has not appeared active. However, the neighboring Halemaumau crater in the middle of Kilhauea Caldera, is more active. Eruptions on the slopes and in the thick forests are described only as flank eruptions, which are not as spectacular as summit eruptions as they usually bring only lava and are not accompanied by rivers of fire.

Lava flows have caused permanent changes to the landscape around Kilauea. Red-glowing magma, reaching temperatures of some 2200°F/1200°C, forces its way almost constantly through lateral channels to the outside, streams out of holes down the sides of the volcano and leaks out of weak spots known as fissures. One of these stretches out from the crater in a southerly direction as far as Ka'u, another east-north-east via Puna to the sea.

Lava sometimes flows through small valleys, which become filled in, and can destroy entire forests. But at the same time a new floor forms on which vegetation can grow, as demonstrated by the Destruction Trail in the National Park.

Lava masses bring great destruction - time and again houses are buried and roads made impassable. In April 1990 all the houses in the coastal village of Kalapana and the greater part of the world-famous Kaimu Black Sand Beach were destroyed. Since then road 130 between Kupaahu and Kalapana has also been partly destroyed. Only one of the village's two churches, the Star of the Sea Painted Church, could be successfully dismantled before the lava reached it; it was later rebuilt on stilts near the end of the road.

Despite all this the recent eruptions are considered mild compared with earlier ones. It was reported in 1790 that Keoua, a Hawaiian island chief and opponent of Kamehameha I, was resting with his troops near Kilauea when they were surprised by an eruption. The majority of the army died, leaving Kamehameha's troops little difficulty in defeating the remainder.

Current methods of assessing natural phenomena such as volcanoes and earthquakes have prevented any loss of life through volcanic eruptions on Hawaii in recent times.
