On the ground and in the air volcanic eruptions pose a direct and indirect threat to people, and property. Pyroclastic flows, lava flows, falling ash, and debris flows are examples of direct flows. Pyroclastic flows are mixtures of hot ash, rock fragments, and gas. They are deadly because of their high temperatures of 850oC or higher and can reach speeds of 250 km/h or greater. Lava flows moves much more slowly and do not pose any direct danger to human life but can produce massive property damage. If volcanic ash comes into contact with rain, it can collapse roofs and damage crops. Debris flows travel quickly through valleys, destroying everything in their paths. During the 20th century pyroclastic and debris flows caused the most eruption-related deaths. Indirect hazards usually accompany or follow eruptions. Earthquakes, tsunamis, rainfall-caused debris flow, and post-eruption disease and famine are all examples of indirect hazards. During the 17th – 19th century tsunamis and post-eruption starvation and disease caused the most eruption-related disease.
One Benefit is that it helped form one of the most beautiful places in the world,Also known as Hawaii.And the dangers is that upon erupting it can kill people and has potential to create mass destruction!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Some of the dangers of volcanoes are that it could wipe out a town in a matter of minutes. Some of the benefits of volcanoes are that they are beautiful when they erupt! *pretty face*

Volcano Benefits The greatest resource from volcanoes is the land formed by the materials they erupt. Volcanic activity has created some of the most scenic and fertile regions on earth. Harnessing the natural heat of volcanic systems has provided a nearly pollution-free source of thermal and electric energy. The steam from The Geysers located in Northern California, which is the world’s largest geothermal field, is sufficient to meet the electrical needs of the city of San Francisco. Volcanic rocks and magmatic rocks also contain valuable ore deposits, such as copper, lead, zinc, gold, and silver. Crushed lava rocks, pumice, cinders, and other eruptive products are a source of raw materials for the road-building, constructing, manufacturing and landscaping industries.http://www.angelfire.com/rings/mibu/hazards.html
Pros- They own it up they produce ash that is great fertilizer they are weaker than a tsunamicons- they kill destroy everything in its path except tsunamis. Cons-The kill people, They break apart things with there lava.
There are a lot of dangers of volcanos some of them include death and destruction in minutes. There are very few benefits of volcanos they include new lava tubes and after it erupts it won't erupt for a while balancing the population.
BLAZING Volcanoes can create islands, which is completed, but volcanoes can cause earthquakes which would injure animal's and people's homes and lava can be dangerous to all life forms. SACRIFICE! SACRIFICE! SACRIFICE!
Benefits- They can severely injure your enemies, the volcanoes can make chemicals that can be made for industrial things, volcanic ash can improve the soil, and etc. (PS julia stole me idea. Only I can be that violent.)
Dangers- They can kill you and other people, the ash and dust can cause breathing problems, HOT LAVA HOT LAVA HOT LAVA, etc.

Although volcanoes have the reputation of being very dangerous, (Volcanoes can kill people and animals. They can be very destructive.) there nevertheless are advantages of living near a volcano.
Volcanoes provide resources for energy extraction, also called geothermal resources. Heat from the earth's crust is being converted to energy. The big advantages to this type of energy are that it is very clean and the resources are nearly inexhaustible.
When a volcano erupts it throws out a lot of ash. At short notice this ash can be very harmful to the environment, but on the long term the ash layer, which contains many useful minerals, will be converted to a very fertile soil.
Nearly everywhere volcanoes are located people use the rich soil for farming. Even after an eruption people still return because of the fertile soil around the volcano.
The dangers of volcanoes is that volcanoes can cause fatal results around inhabited areas by destroying what ever's in the magma's path. However the benefits of a volcano is the ash. The ash is very good for soil.

There are no benefits of volcanoes. Some of the dangers are; death, lava, and hot rocks.

They're dangerous because they can destroy places and a benefit is that they're cool
It kills people and makes a lot of different rocks.
There are a lot of dangers of volcanos some of them include death and destruction in minutes. There are very few benefits of volcanos they include new lava tubes and after it erupts it won't erupt for a while balancing the population.
They are dangerous and can make rocks
Dangers are lots of death and destruction and benefits are if magma makes it to China it will BURN ALL THE PEOPLE AND REDUCE THE POPULATION!!!!!
they destroy stuff and the benefits are they made islands
Volcanoes have formed beautiful places on this Earth but create such damage that can servierly hurt people.
Volcanoes form rocks and volcanoes can kill people
Volcanoes are very magnificent things but are also dangerous and can kill you with the hitting of plates.
Volcanoes can shoot out lava and burn stuff, and debris can go flying everywhere! But volcanoes can also make cool rock formations, and islands.
If a volcano erupts near a town people can die, if they get hit by lava
Benefits of volcanoes is they can severely damage your enemies. :) Dangers of volcanoes include hurt/killed people, ruined homes etc.
Some dangers of volcanoes are the lava it will destroy villages and benefits are they will make new islands.
Volcanoes can destroy peoples houses, and it can destroy people them selves, by there moltent hot lava.
People can die by getting hit by lava.

The benefits of Volcanoes that Volcanoes Are so pretty . The dangers are The hot lava.
the dangers of a volcano are that they can erupt,creating massive panic to nearby towns,settlements,and villages.
The dangers of a volcano is that it can spew out magma and it can hurt you.

They're dangerous because they can destroy places and a benefit is.
They're dangerous because they can destroy places and a benefit is that they're cool
MR.MAN
The benefits are very pretty but the dangers are the lava because it could kill you but VERY slowly.
volcanos makes lava and burns things but also forms ifnious and obsidien and makes islands

They can kill people and destroy land
It is dangers of being near a volcano because you might live there and a benefit is they make island
The dangers of volcanoes are the hot magma that pours out of the volcanoes, but a benefit is that you can get pretty igneous rocks.
land slide, pyroclastic flow, lava, smoke, ash, and debris. they can form islands.

THE LAVA WILL FLOW AND EVENTUALLY HIT YOUR HOUSE BE AFRAID!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
They destroy stuff and the benefits are they made islands
The lava will burn everything and destroy land and stuff.
LaVa WiLl HiT YoUr HoUse N KiLl U
They can destroy land and peoples home and they can also burn people alive.
Dangers are that they destroy stuff and the benefits are they make islands
The dangers are you can die, your house can burn down. The benifis are it can form a island, and the the ash is good fertilier.
They can destroy houses and the benefits is that they can make islands.
They can create land mass but they can also destroy.
By Desi.
Benefit: Could kill predators of your animals
Danger: It could burn your land
lava will melt and kill every thing but the ash is really good soil stuff !
They destroy stuff and the benefits are they made islands
original comment from mackenzie E.
Firstly the ash makes good fertilizer, but the lava will kill your family and you house
Volcanoes can destroy land and, but it can also make a island.
one danger of valcanos is there hot.
Volcanos can destroy land and burn things. It can also make islands and the ash from the volcano can be used as fertilizer.
When Volcanic Ash erupts out of a Volcano it can be deadly to breath in.
