Natural Disasters

Is an effect from a natural hazards. They take a huge effect on the environment. They usually result in many deaths. Natural disasters usually are just natural if there is no human involvement.

TORNADO

ES

There are many types of tornadoes. A few of them are…. Supercell Tornadoes, Landspout,Gustnadoes, Waterspouts, Dust Devils and Firewhirls.

Supercell tornadoes- are the most powerful kind of volcano. They are great big thunder storms with such a strong wind they can throw ANYTHING Landspout- are generally

weaker than a supercell and are not related to a wall cloud. Gustnadoes-are very

weak and have a very few minute life to live. They usually follow the front of a thunder storm. Watercell- are formed

over a larger area of water. They create small thunder storms and rarely turn in to a supercell tornadoes.Dust devils – formed on

deserts on hot, dry, and lightly breezy days. They are not associated with clouds or thunder storms.

VOLCANOE

S

An eruption maybe a deadly disaster alone without the lava and ash. The lava is produced during the eruption is superhot rock and is crumbly and gluey. The volcanic ash. There are many volcanic dangers such as lava flows, pyroclastic flow, lahars, gases landslide avalanches and tsunamis.

Krakatoa

EARTHQUA

KES

Earthquakes are one of the most powerful event on the earth causing landslides and avalanches. They can also cause fires, and broken gas and power lines!!! An earth quake is when the tectonic plates move. This causes buildings to collapse, and cracks in the earth.

HELP!!!

HELP!!!

Blizzards

Blizzards are strong snow storms. This happens when the cold air is moved to warmer climates from the arctic. Most blizzards end with a very unusual warm period.

Floods

Floods cover a normally dry area of land most floods are harmful. They erode and carry away houses and a lot of other things. Most floods cost at least 1billion dollars to repair the damages.

Floods are created mostly from rainfall on snow, ice jams, rainfall and snowfall.

Tsunami Tsunamis are huge walls of

water that travel faster than jets. Tsunamis are created from earthquakes in the ocean and lifting up the water strongly then coming to shore heavily. The worst tsunami was Christmas 2004, it was a

9.2 earthquake so powerful it actually sped the rotation of Earth!

Drought

Drought is when the area common for rainfall has unusually dry weather. The effects are that the crop is reduced and increased livestock and wild life deaths.

This happens from drought!

Avalanches

An avalanche is a pile of rock debris and/or snow that moves rapidly down a mountain. The causes of an avalanche is a loud noise or voice causing the ground to vibrate making the snow/rock debris to loosen and move down hill
