        Volcano production begins with a body of rock called the mantle which is between the molten iron core and the thin crust at the surface. When the rock from the mantle melts, it moves through the crust, and to the surface, and releases pent-up gases, the volcano erupts. This solid rock melts because extremely high temperature and pressure cause it to. Then it becomes magma. When a good sized amount of magma formulates, it rises through the denser rock layers, toward earth's surface, where it is then considered lava.
        When a volcano erupts, a lava flow may occur. A lava flow is lava that flows through towns and do lots of damage. Fortunately, lava flows do not usually cover much area, so the damage is limited. Debris flows can also occur while a volcano is erupting.They are very serious, but a lot of people are not aware of them. They often occur while flowing downhill.
       Scientists are becoming more and more skilled at spotting the warning signs of a volcano eruption. Although some barriers lie in the way. It is very difficult to pinpoint exactly when an eruption will happen. With many volcanoes erupting every 100 years or so, it is difficult to keep track of them. If we were to set up monitoring devices, every volcano wouldn't come as a surprise to us. For more information about forcasting volcanoes click here

                                             Mount Saint Helens
Last time Mount Saint Helens erupted(May 18, 1980), no lava came pouring out, and pour down in flanks. This may be what forms inside of your head when someone says ''volcano", but it is not always accurate. But the eruptions that come from Mount Saint Helens are not common. Mount Saint Helens' eruption are called explosive eruptions. It is very important to know what kind of eruption a volcano is going to have before hand, so you can prepare accordingly.
Mount Saint Helens is 8,363 ft. high. It can also be called a stratovolcano. When it erupted in 1980(picture) the top 1,300 ft. disappeared within minutes. The blast covered an area of more than 150 square ft., and sent thousands of tons of ashes into the upper atmosphere. Mount Saint Helens is located in Washington, USA.

MountAsacha

        The elevation Of Mount Asacha is 6,265 ft. It is at 52.35N and 157.83E. It is located in Russia. Asacha is also a stratovolcano, just like Mount Saint Helens. It is made up of several extinct cones.
        Its best preserved crater is located in the southeastern most cone. Asacha is located just north of Khodutka. Over time it has been eroded into summits, which have inner slopes that are steep and rocky. Pyroclastic flows from Asacha form a large pumice plain around it. Asacha has never erupted in historical times.
