Hurricane causing numerous deaths and forcing hundreds of thousands of people from their homes. So what’s a hurricane? What’s the difference between a hurricane and a mere storm? A hurricane is a severe tropical storm that forms in the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, or the South Pacific Ocean east of 160E. Hurricanes need warm tropical oceans, moisture and light winds above them. If the right conditions last long enough, a hurricane can produce violent winds, unbelievable waves, heavy rains and floods. Hurricanes rotate in a counterclockwise direction around an “eye”. A tropical storm becomes a hurricane when winds reach 74 miles per hour. The Atlantic hurricane season begins June 1 and ends November 30. The East Pacific hurricane season runs from May 15 through November 30, with peak activity occurring during July through September. When hurricanes move onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars.

Originally, the interior of the earth is filled with hot magma. Under tremendous pressure, the hot magma will break through the earth's crust and spouts out, causing the volcano. 原来，地球内部充满了热的岩浆。在巨大的压力下， 滚烫的岩浆会冲破地壳，喷出，造成火山。
Flash floods occur suddenly due to rapidly rising water along a stream or lowlying area. 山洪突然出现是由于迅速上涨的水沿着小溪或低 洼地区奔流而下。

How does a typhoon happen?
When lots of sea water gets hot in the summer sun, it evaporates（蒸发）into the air.This makes the air hotter. When the air gets warm enough,it starts to move higher up into the sky. Then,cooler air around it rushes in.It fills the space that is left. After the air gets warmer, it starts to move quickly,making wind. The wind goes in circles, and it keeps moving higher in the sky. The warmer the air gets, the quicker the wind moves. And when the wind moves faster than 30 meters a second, a typhoon begins.

Peak Monthes and the Landing Area
The typhoons of China mostly come from the northwestern Pacific ocean. The landing time mostly from July to November.The earlist one would land in May, while the last one ofen occurs in December.

1. tsunami
• A tsunami, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater, landslides, and other disturbances above or below water all have the potential to generate a tsunami.
The damage
• Tsunamis cause damage by two mechanisms: the smashing force of a wall of water travelling at high speed, and the destructive power of a large volume of water draining off the land and carrying a large amount of debris with it, even with waves that do not appear to be large.
4.volcano
• A volcano is a rupture in the crust of a as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

• A huge tsunami on March 11th, 2011, which caused by the earthquakes in Japan influenced the Mexico's Pacific coast, thousands of fishes assembled together, looks like a oil leakage(原油 泄漏）
Landslides& Mudflow Mitigation
• Get a ground assessment of your property • Minimize home hazards (plant ground cover on slopes, build retaining walls, and in mudflow areas, build channels or deflection walls to direct flow around buildings) Recognize landslide warning signs: • Doors / windows stick or jam for the first time, new cracks appear in plaster or foundations, outside walks, walls, or stairs pull away from buildings, underground utility lines break, bulging ground appears at base of a slope, ground slopes downward in one direction and may begin shifting in that direction under your feet; faint rumbling sound that increases in volume as landslide nears • Make evacuation plans, planning at least two routes allowing for blocked and closed roads • Develop an emergency communication plan and ask an out-of-state relative or friend to serve as the family contact • Purchase flood insurance.
