Lava dome

The fragile molds were casted in the 19th century to preserve them further. A lot of mystery lays round them, because these people seemed to be frozen in time in contorted positions. It has recently been discovered that lava was not the cause of death for these people, the lava would have taken six days to reach the people of Pompeii. For decades, it was thought that the ash killed them by suffocation. A cast found covering their mouth seemed to prove this. But today, it is shown that this may…

Would people recognize the difference between “active volcano” and “Holocene volcano?” Well there is no difference, people just use the term “active” wrong. Scientist say that, “...it is misleading to restrict “active volcano” to recorded human memories: we prefer to add another identifying word (“historically active” or “Holocene volcano”).” People are probably confused on what these terms actually mean because no one would see the difference or wouldn’t care. Volcanoes are very old, they…

The purpose of this paper is the explain a natural phenomena, Axial Seamount. Even if the reader has no knowledge of Axial Seamount, they will be able to fully understand the content of this paper. They will learn facts about Axial Seamount such as what it is, on what plates it is located on, what landforms are around it, etc. Axial Seamount is an underwater volcano located in the Northeastern Pacific Ocean, about 483 kilometers (300 miles) off the coast of Oregon. Because its frequent volcanic…

the times the volcano itself gives early signs of eruption. Some of those signs are small earthquakes beneath the volcano, swelling or increase heat and gases coming out of the volcano. A volcano is a mountain or hill, having a crater or vent where lava, rock fragments, hot vapor, and gases are being released from the earth's crust. One of the many active volcanos in the world is Mount Agung. Mount Agung to this day is still one of the many active volcanos in the world. Mount Agung is located…

There are a total of ten different landscape regions located within the Pacific Northwest. The rocks that are within each region provide the foundation for the landscape within the region. The study of the rock located in the region tells us about the geologic past and provides insight on the materials and processes from which the landscape was formed. I will briefly discuss each of the areas and provide insight on the types of rocks in which they are formed from. We will start with the Basin…

my paper I will be giving information on how often do volcanoes erupt. First,I will explain how magma can trigger volcanic eruption. Next, I will discuss how buoyancy can also trigger a volcanic eruption. Finally, I will predict how pressure from gases in the magma and magma chamber can cause a volcanic eruption,and give some more details about my volcano. It depends on the volcano to erupt oftenly. Some volcanoes erupt very often (and some like Kilauea almost never stop). On the other hand,…

Volcanoes can destroy the land all around them. There are volcanoes all around the world, some may be dormant then may become active. There are some volcanoes that destroyed all of the living things around them, such as, Vesuvius, and Mt. St Helens. Some volcanoes are very different from the others. There could be different ways a volcano could erupt. Vesuvius and Mt. St Helens both destroyed a great amount of land around them. Furthermore, the two volcanoes caused Earth quakes. In addition,…

was formed on plate boundaries. Mount Etna is called a Stratovolcano. A Stratovolcano is made from layers of ash and lava. Another name for this volcano is a composite volcano. Etna is cone-shaped, like most composite volcanoes are. Mount Etna is made from different rock types. Some of the major rocks found on this volcano include, trachyandbasalt/tephrite…

On August 24th in 79 AD at approximately 1300 a cloud appeared over the Roman city of Pompeii. This was all the warning the residents had before the nearby volcano, Mount Vesuvius, erupted. Huge quantities of scalding hot ash, pumice and lava pebbles were thrown into the sky. This then cascaded down across an extensive area. Most of the 20,000 residents fled for their lives but approximately 2,000 people stayed behind and hoped to wait out the disaster in their homes. Those who stayed…

The map is almost uncannily similar to today's: a spray of black dots showing the recorded sightings of a foul grey haze spreading across Europe, from Helsinki to Naples, from Heligoland to Mallorca, and reaching eventually to Aleppo and Damascus – and all of it caused by clouds of ash from an immense volcano erupting far across the sea in Iceland. But this was a map made from data collected in 1783. The volcano was called Laki, it erupted for eight dismal months without cease, ruined crops,…
