During this stage, the volcano erupts small amounts of lava very infrequently, often several million years apart. Eventually, erosion breaks the volcano back down to sea level where it becomes an atoll (coral atoll stage). Because atolls are the growth of coral and marine organisms, when the Pacific Plate carries the atoll to waters too cold for these organisms to survive, they erode away into seamounts and
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
I choose this one because this explains how deadly this volcano was and is and what it could do if this happened again. "Then more terror. As the volcano loses energy, the molten rock and ash mix together to create a super heated wave that rushes down the mountain at 80 miles an hour. This burning avalanche is known as a pyroclastic flow.
When Mount Vesuvius erupted in 79 A.D it caused a lot of destruction throughout the region in Italy. In 62 A.D, there was a fatal earthquake that damaged towns, cities, this earthquake set Mount Vesuvius in 79 AD which the volcano erupted strongly with streams of hot gases, molten rock that hit Herculaneum. The city quickly was filled up with ash, pumice, molten rock, hot gases from the volcano. When Pompeii was hit not a while after ash, pumice, molten rock fell on top of the town. Some died in their homes or shops from the buildings collapsing while others died from the poisonous fumes that were ejected out of the volcano.
Convection Currents The Alaskan Way Viaduct will collapse if an earthquake happens. Tectonic plates rubbing together causes an earthquake. What causes them to rub together? An earthquake happens through a sequence of cause and effect. Altogether, temperature, density, and convection currents work together to cause an earthquake.
Seismic waves are made when some kind of energy stored in Earth’s crust. Natural events such as volcanic eruptions and meteor impacts can cause earthquakes, but most of the naturally-occurring earthquakes are activated by movement of the earth 's plate. The Haiti Earthquake included many details common to Earthquakes and caused damage and destruction to property and lives that affected the region, but the area has recovered in its after math. Many parts of this disaster are common to Earth Quakes like the Haiti Earth Quake .Haitian capital of Port-au-Prince was a part and was also hurt. The disaster was a Earthquake it
Oh my gosh! The ground is rumbling! Could it be… the Yellowstone Caldera? Now, you might be asking “What’s the Yellowstone Caldera?” I would tell you to run, but since it isn’t actually erupting, I’ll tell you what it is. 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.
It is one of the world’s most active stratovolcanoes. It is located in Skamania County, Washington which is south of Seattle, Washington and it is 8,336 feet tall. These people died due to being exposed to the hot ash the volcano produced and inhaling it which asphyxiated
When a hurricane comes onto land it rapidly gets weak. Hurricanes can cause natural disasters, destroy many things, and can cause a storm surge. The first effect of a hurricane is, according to “Causes and Effects of Hurricanes,” “When a powerful hurricane hits land, it can cause more damage to life and property than any other natural disaster.” The effects of hurricanes include strong wind, inland flooding, and tornadoes. This means that hurricanes can cause destruction to the earth when the hurricane hits land. This also shows that after a hurricane hits it may cause strong winds, inland flooding, and tornadoes.
Iceland was created by a hotspot, much like Hawaii, and due to a combination of hot spot activity and plate tectonics, Iceland has undergone many geologically processes. The mantle plume itself is traveling toward the northwest part of the island, creating amazing geological features as it goes. Some of Iceland’s unique features include volcanoes, geysers, lava fields, rift valleys, hot springs, and subglacial volcanoes. Currently Iceland has over 20 active volcanoes. The Mid-Atlantic Ridge and the mantle plume create earthquakes and new volcanoes.
