The relatively small size of the islands - no more than a speck in the vast sheet of the ocean - the basis of the traditional tourist fears: earthquakes, tsunamis, hurricanes and eruptions.
The presence of an active volcano on the Big Island is hundreds of oscillations per year. Most imperceptible to humans, especially on other islands. The last earthquake in 2007? Year (6 points on the Big Island, at about 4 points. Oahu) and caused no damage and casualties. Earthquakes in Hawaii where safer California: there - the collision of giant tectonic plates causes large earthquakes here - out of the magma through cracks in the slab - small and local.
Unpredictable and frightening phenomenon (in the light of the tragedy in Indonesia), tsunamis periodically come to the Hawaiian Islands. More or less significant tsunami affected islands approximately every 25 years. Waves pose the greatest threat to the Gulf coast and low-lying areas of the coast. Hawaii all such areas marked with warning signs, set on the shores of the islands of the siren. Hawaii ravernuta most advanced system in the world warning of a tsunami. In the Pacific Tsunami Warning Centre conducted four-hour duty.
Hurricanes - relatively rare in Hawaii. From 1832 to 1949 was recorded only 19 tropical cyclones. However, strong gales visited the main Hawaiian islands since time immemorial. The first officially recognized by the hurricane occurred in August 1950. Since that time, Hawaii was recorded five hurricanes or tropical storms, causing serious damage. Hurricane Nina (1957) was accompanied by a strong wind record in Honolulu. Hurricane Dot (1959) caused damage to the island of Kauai. Hurricane Estelle (1986) caused a very high waves on the island of Hawaii and Maui, and flooding on the island of Oahu. On the island of Kauai came the main force of the hurricane Willow (1982), brought the damage to 234 million dollars. The destructive power of hurricanes demonstrated Hurricane Inika (1992). The epicenter of the hurricane passed over the island of Kauai. The strength of the wind reached 200 kilometers per hour, with damage estimated at $ 2.3 billion.
As can be seen, on the Hawaiian island comes a surprisingly small number of hurricanes. In part, this is due to the fact that the island is very "small target" in the midst of a vast ocean. In addition, the islands are located in the central Pacific Ocean, with cooler than in tropical areas, water. Since hurricanes gain energy from the warm waters of the tropics, a storm in the central Pacific Ocean is less intense than in the Atlantic. There are other factors that prevent the appearance of hurricanes in Hawaii. The interaction of the trade winds blowing from the east, with the rotation of hurricanes counterclockwise causes that hurricanes are shifted far to the south of the Hawaiian ostorovov.
