Following the gentle explosions of the pre shield stage, the submarine phase begins with pillow lava eruptions. The volcano slowly makes its way up to sea level and the submarine phase ends when it is shallowly submerged. The explosive phase begins when the volcano breaches the surface. Upon contact to air, a large amount of steam is produced and the lava becomes volcanic ash. Following the explosive phase is the subaerial stage which primarily consists of the “shield” shape forming and landslides.
Altogether, temperature, density, and convection currents work together to cause an earthquake. The layer of the Earth are made up of the lithosphere, asthenosphere, mesosphere, and the core. In the lithosphere, there is the upper rigid mantle, oceanic crust, and continental crust. The oceanic crust and continental crust is what makes up the lithosphere. Inside these layers, temperature and density all play a role in the layers of the Earth.
Many witnesses said they could hear two distinct explosions few second apart. If it was only attacking then it would only be 1 explosion not 2 explosions. Another reason why it was external mine because the report from the diver who swam down and invent the bottom plate of the ship. The 3 metal plates of the ship were bent inward however, if it was an internal explosion, then it the metal plates would be bent outward not inward. The 1911 report with Vreeland Broad had agreed that it was a explosion of the magazines were triggered by an external force BUT the damage to the USS Maine was more powerful that the Sampson Board which was the 1898 report.
Subduction is the process when in which one tectonic plate moves under the other, sinking into the mantle as the plates converge. Regions where subduction takes place are known as subduction zones. Subduction zones tend to have very high rates of earthquakes, volcanism, and mountain building. Some examples of volcanoes that are located above subduction zones would be Mount St. Helens, Mount Etna, and Mount Fuji. Furthermore, the strains, which are a result of plate convergence, are known to be the cause of at least three different types of earthquakes.
The Yellowstone Caldera is a volcanic feature formed by the collapse of a volcano into it’s own magma chamber in the North Western edge of Wyoming. Calderas are cool, I’ll give you that. But do you know what’s even cooler? A supervolcano. Supervolcanoes are even more powerful than regular volcanoes.
A long time ago when the ground starts to shake, the ocean ate up the coasts, and a dusty vortex sucks up cows, it meant the gods are mad. The ancient Greeks had a way of explaining the cause of many known natural disasters such as volcanic eruptions, earthquakes, tsunamis, etc. Whenever a natural disaster occurs someone somewhere did something to get the gods mad even though no one knew the real cause is the ancient Greek's mentality. Coming back into reality, science says otherwise. We can make conclusions about the cause, effect, and origin of any natural disaster before it happens due to an advancement in modern-day technology.
Tidal waves can likewise be created by submerged volcanic ejections. Volcanic emissions are another catastrophic event, and they are brought on by magma getting away from inside the earth. A blast happens, discharging the magma from a bound space, which is the reason there are frequently likewise gigantic amounts of gas and tidy discharged amid a volcanic emission. The magma goes up within the well of lava, and spills out over the encompassing territory as
Tsunamis happen when the plates on the crust of the earth move, therefore moving the entire plate so that the water rises and is pushed forward, therefore causing a tsunami (Drohan, 2009, p.21). These tectonic plates are everywhere, under everything from the biggest mountain to the smallest hill. Though it is infrequent, volcanoes have been known to cause tsunamis. It happens when to volcano begins to erupt, but instead of coming out from the top of the volcano a lateral blast shoots out from the side. Next, a quickly moving avalanche of lava pours into the water near it causing the wave to travel to distant coastlines (Springer, 2005).
- Crust - cool, lightweight, brittle, which floats on top of mantle. It is the outer layer of earth. Tectonic processes reshape continents and also cause earthquakes - Tectonic plates- plates caused by convection currents in the mantle that causes earthquakes. - Ocean basins form where continents crack and pull apart. - Magma – is molten rock
Yan covers these phenomena like Earthquakes which were previously thought to had been caused by the sea god, Poseidon, or that storms were caused by Zeus and that the Sun came up everyday thanks to Helios. Which today are now proved through orbit of the Earth and low and high air pressure. Even though we both had our own way of explaining these phenomena, they varied drastically. While Odysseus was traveling with his men on his ship they and alone on his raft he stumbled along unexplainable storms that battered his ship and his crew which were thought
Mauna Loa is located in Hawaii near Hilo the largest city in Hawaii. The absolute location of mauna loa is 19.4795 degrees north and 155.6027 degrees west. Mauna Loa is a shield volcano. A shield volcano is a mountain that has a gentle slope that produces a large amount of fluid lava normally. The lava turns explosive if water gets through the vents of the volcano.
