Lava

between 300,000 and 600,000 years ago. Despite this, about 90% of the basaltic shield volcano found on the surface is made from lava flows that occurred less than 1000 years ago while 70% of the actual volcano’s surface is 600 years old or younger. The volcano gets its name, Kilauea, from the Hawaiian word meaning much spreading or spewing, referencing the frequent lava flows. Location

of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water. The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions

Mt.Etna is an active Stratovolcano which means that it is a shaped like a cone made of layers of lava, hardened ash, and other material erupted from the main volcanic vent. Also well known for a composite volcano. The formation of all stratovolcanoes takes place on boundaries between two tectonic plates where an oceanic plate is subducting into the mantle beneath the continental plate. In this case, the two plates involved are the Eurasian plate and the African plate. These types of volcanoes have

Americans across the country. It is also interesting to analyze and study volcanic eruptions that occurred in history in the past and are currently erupting in continents globally. Many people believe that the damage caused by volcanoes results only in the lava released from the crater. However, gases and tiny shards of glass prove to be more deadly, and they travel great distances through the atmosphere as gusts of wind propel them in all directions. In conclusion, volcanoes interest me the most out of all

Nevado Del Ruiz Eruption The Nevado Del Ruiz Volcano eruption was one of the most devastating events in the 20th century.The Nevado del Ruiz (located in Armero, Colombia) volcano eruption occurred on November 13, 1985. Armero, Colombia is located in the province of Tolima. The population at the time of the disaster was 31,000.The Volcano has erupted a couple times before the disaster one in 1595 it killed 636 people and another one in 1845 costing about 1,000 people lives.After the Nevado Del Ruiz

countless outpourings of lava that advance great distances from a central summit vent or a group of vents. Extensive study of the Hawaiian Islands revealed that they are constructed of a myriad of thin basaltic lava flows averaging a few meters thick intermixed with relatively minor amounts of pyroclastic ejected material. During eruptions these outpourings help keep these volcanoes safe. When these volcanoes erupt lava fountains out form the volcano and is hot liquid lava is thrown into the air but

Popo is a composite cone volcano. Being a composite cone volcano, El Popo is characterized by a steep cone shape, which was created by many composite layers of material pouring out over numerous eruptions. The lava that comes out of El Popo is extremely viscous. The highly viscous lava does not travel very far, and typically cools down rapidly. Scientists believe that El Popo is about 730,000 years old. It has erupted more than 15 times since 1519. In 1994 El Popo produced gas and ash, which

The formation of LIPs associated with superplumes might have affected sea level, climate, and may have caused the extinction of some species. Because when volcanic eruptions begin, the huge quantities of basaltic lava spew out of the ground, the hot basaltic lava has low viscosity that can erupts the localities, and it can flow tens to hundreds of kilometers across the

There were ashes everywhere. Maybe Mt. Vesuvius was just on fire. I noticed something on the edge of the mountain. It was very strange, it was red and glowing. It looked like a mass of fire but instead of flames it was gloppy and looked sticky. It was lava! I ran out of my room and outside people were trying to flee from Naples, and Pompeii where I live. They were trying to escape from the waves of gas and ash.

through the crust and spits out ash,gas and lava. Volcanos can be deadly, the gas can kill you and the ash can burn also bury you. There are different kinds of lava, one is called pahoehoe it is a fast moving lava that is smooth looking. Another one is aa, a slow moving lava that is sharp looking like glass. There are also different kinds of lava flows, one is the pyroclastic which is an explosive lava flow that throws out rocks and lava. The magma/lava comes from a chamber in the crust called the
