Niihau Island HistoryHistory of Niihau Island
McMurtry's crew found two younger and slightly smaller tidal wave reservoirs in South Point on the Hawaiian island, one 50,000 years old and one 13,000 years old. It proposes that the spring of Tzunami are the two Ka Le U-boat landslips from the sides of the near-by Mauna Loa Vulcano. Fatal mudslide -induced tidal wave events occur on vulcanic islets around the globe and pose a threat to the eastern United States.
"We' re finding them everywhere, but we don't know of any historic cases, so we have to go back in time," said Anthony Hildenbrand, a volcanoologist at the University of Paris South in France who assisted in identifying the old cemetery. Whilst landslide-like tidal waves can have a disastrous effect locally, they loose their strength in the open sea and do not damage remote shorelines like seismic tidal waves.
Hildenbrand said to OurAmazingPlanet that the huge landslips seem to occur in times of increasing ocean floor temperatures, even though the weather is hotter and damp. Scientists are speculating that the shift from lower to upper ocean floor could destabilise the sides of a volcano island and heavy rainfall could steepen its precipitous hillsides and cause landslips.
The Hawaii Islands have seen at least 15 huge mudslides over the last 4 million years, the last of which took place just 100,000 years ago, according to the U.S. Geological Survey. A boulder that's slipped off Oahu is the greatness of Manhattan.
The invasion of the island of Lehua seems to have disappeared after officers carried out a conservation effort to save endangered sea birds.
The invasion of the island of Lehua seems to have disappeared after officers carried out a conservation effort to save endangered sea birds. The' iswa or Great Frigatebird sweeps deep over a group of lorries, stacking of gear and a Jet Ranger chopper at the north end of Niihau. When I followed its black-wing shape with the binocular, the square pointer made several passports and then went back to its place to sleep on Lehua Island, a grey-brown tufa conical island, just a thousand meters above the Kumukahi Canal of Niihau.
At the end of August and beginning of September, a team of wild life pros worked in both Niihau and Lehua with a computer-controlled chopper to supply lures for the wild life on the jagged island. There are signs that there are no longer signs of life in Lehua one months after use. Surveying crews find no feetprints on caves or other signs of rodent activities, according to Sheri Mann, director of the Kauai Bureau of the State Department of Forestry and Game.
Lehua Island is designed to enhance the habitats for frigate birds and a dozen other birds and plants on the small island, just as the fauna has grown after similar extinctions on other off-shore Hawaiian Isles such as Mokolii Island off Oahu and Mokapu off the coast of Molokai. Following the extermination of African dark rats on Mokolii, the success of storm-divers was spread, Shore Nazaka germinated, and marine rat-influenced varieties such as pipipis and an Amazon shrimp became plentiful.
In the Palmyra Atoll just South of Hawaii, long gone sea bird populations successfully nested after rats were removed, coastal crustaceans blossomed and indigenous seed germinated where it was once ate. Now Lehua has received three uses of light navy rats pellet containing Diphacinon - less than a poundage of anti-coagulant in several thousand quid of food-grade grains such as grain and oat and other rat-friendly foods.
Lehua's affiliates are the State Department of Land and Natural Resources, the U.S. Department of Agriculture in Hilo, the National Wildlife Research Center of the U.S. Department of Agriculture in Hilo, Niihau Ranch, the U.S. Coast Guard, the National Tropical Botanical Garden and various other affiliated organisations and authorities.
Hundreds of small islets from the Ecuadorian Ocean to the Antarctic have been freed from worms and other invaders. Might there be an island? Although their area is small, they are important jars of biodiversity - home to many threatened and once home to many extirpated varieties. I could see through my telescopes the whitish, browns and blacks of storm birds, large frigates, gannets, noddies and other birds moving on the thermal over Lehua's oblique back.
Meanwhile, one type, the minute Sturmschwalbe, is completely absent - probably because it is particularly susceptible to rivals due to its small height and its loud nesting customs. Maybe it can reestablish itself on a rat-free Lehua. Hawaii is already in the process of developing a much greater plan to rid Kahoolawe Island of kinds such as the mouse that are hindering the replanting of the island.
