IF IT SOUNDS LIKE A VOLCANO

Kilauea,Hawaii,1872
                   Kīlauea is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaiʻi. Located along the southern shore of the island, the volcano, at 300,000 to 600,000 years old and going above sea level about 100,000 years ago, it is the second youngest product of theHawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain. Because it lacks topographic prominence and its activities historically coincided with those of Mauna Loa, Kīlauea was once thought to be a satellite of its much larger neighbor. Structurally, Kīlauea has a large, fairly recently formed caldera at its summit and two active rift zones, one extending 125 km (78 mi) east and the other 35 km (22 mi) west, as an active fault line of unknown depth moving vertically an average of 2 to 20 mm (0.1 to 0.8 in) per year.

         Kīlauea's eruptive history has been a long and active one; its name means "spewing" or "much spreading" in the Hawaiian language, referring to its frequent outpouring of lava. The earliest lavas from the volcano date back to its submarine preshield stage, and have been recovered by ROVs from its submerged slopes; other flows have been recovered through core samples. Lavas younger than 1,000 years cover 90 percent of the volcano; the oldest exposed lavas date back 2,800 and 2,100 years. The first well-documented eruption of Kīlauea occurred in 1823, and since that time the volcano has erupted repeatedly. Most historical eruptions have occurred at the volcano's summit or its southwestern rift zone, and are prolonged and effusive in character; however, the geological record shows that violent explosive activity predating European contact was extremely common, and should explosive activity start anew the volcano would become much more dangerous to civilians. Kīlauea's current eruption dates back to January 3, 1983, and is by far its longest-lived historical period of activity, as well as one of the longest-lived eruptions in the world; as of January 2011, the eruption has produced 3.5 cubic kilometres (0.84 cu mi) of lava and resurfaced 123.2 km² (48 sq mi) of land.

          Kīlauea's high state of activity has a major impact on its mountainside ecology where plant growth is often interrupted by freshtephra and drifting volcanic sulfur dioxide, producing acid rains particularly in a barren area south of its southwestern rift zone known as the Kaʻū Desert. Nonetheless, wildlife flourishes where left undisturbed elsewhere on the volcano and is highlyendemic thanks to Kīlauea's (and the island of Hawaiʻi's) isolation from the nearest landmass. Historically, the five volcanoes on the island were considered sacred by the Hawaiian people, and in Hawaiian mythology Kīlauea's Halemaumau Crater served as the body and home of Pele, goddess of fire, lightning, wind, and volcanoes. William Ellis, a missionary from England, gave the first modern account of Kīlauea and spent two weeks traveling along the volcano; since its foundation by Thomas Jaggar in 1912, the Hawaiian Volcano Observatory, located on the rim of Kīlauea caldera, has served as the principal investigative and scientific body on the volcano and the island in general. In 1916 a bill forming the Hawaii Volcanoes National Park was signed into law by President Woodrow Wilson; since then the park has become a World Heritage Site and a major tourist destination, attracting roughly 2.6 million people annually.

        The noise made by the bubblng lava is not great,heard as we heard it from our lofty perch.It makes three distinct sounds-a rushing,a hissing,and a coughing or puffing sound;and if you stand on the brink and close your eyes it is no trick at all to imagine that you are sweeping down a river on a large low-pressure steamer,and that you hear the hissing of the steam about her boilers,the puffing from her escape pipes,and the churning rush of water abaft[behind] her wheels."The Great Volcano Of Kilauea",Mark Twain.
