Recommended: Impacts of volcanic hazards
The government should spend more money on volcano and earthquake research, because unstoppable natural disasters are around the world. Volcanoes and earthquakes can not be stopped, or prevented. However, people at monitoring stations can predict them and warn the people, but we can’t do that without knowing when they are going to happen. It is natural for people to die, but in mass amounts and us knowing we could’ve saved them all is very bad. My three points are the average amount of natural disasters in the United States, the damage they can do, and the way technology has helped us before.
The United States has many volcanoes and earthquakes spread across the country. All together, there are 169 active volcanoes, and 54 are a very high threat to surrounding people. A lot of these volcanoes have actively erupted before, and supposedly will soon. Seeing as though volcanoes are highly dangerous because of their lava, they also have many other features that can harm us in the long run. Many earthquakes happen in the United States, and many of them have been very

Volcanoes can block out the sun causing a ‘winter’, as we saw in June of 1816; the explosion in Indonesia, around the world, caused half a foot of snow in America. This same eruption also killed agriculture all around the world, leading to famine and killing even more people. To add to that, the eruption caused the cholera epidemic, killing millions of people around the globe. The San Francisco earthquake of 1906, happened along the San Andreas fault line in California, but was felt as far as Oregon and the middle of Nevada. The shaking lasted about a minute, and killed about 900 people from the earthquake itself and the fires following it. As shown, both volcanoes and earthquakes are very deadly, and caused plenty of deaths not only by themselves, but also in the events occurring after the original
Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.
There are many pro’s for attempting to forecast an earthquake or volcano. Forecasting an earthquake or eruption saves lives and property, mainly by preparation, as there is no way to prevent these events with today technology.
...815 eruption of Mount Tambora. With over 70,000 deaths and a rating of 7 on the volcanic exclusivity index, this eruption is one of the largest in recorded history. Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.
Boom! A once ice-capped mountain peak explodes as ash fills the air. “‘Vancouver, Vancouver, this is it!’”Those were the last words of expert geologist David Johnston (Gunn 561). In 1980, Mount Saint Helens of the state of Washington erupted, filling the air with ash and causing mudflows powerful enough to lift tons. It decimated everything in its path. The eruptions, mudflows, and ash caused great damage on the landscape, yet it gave us information on how catastrophes happen and how they affect society and the surrounding landscape. The data acquired can also help us understand the way the landscape was formed. Mount Saint Helens caused much damage, but also helped people understand the science behind it.
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Volcanoes can cause damage by spewing lava, but earthquakes before the eruption can also cause damage. These earthquakes open fissures and let magma out to the surface. When the magma exits these fissures, streams of lava up to hundreds of feet can shoot into the air. The picture below shows the lava erupting from the fissures created by the earthquakes in...
Vast areas of the USA would be destroyed, the US economy would most likely collapse, and thousands of people might die. If these super volcanoes do exist, they would have many other effects in the world. For example, once the part of Yellowstone erupts, if it were to rise up to 30, 40, 50 km we would instantly be distinct. Other super volcanoes would be killing ten thousands of people, plants would die and crops would have less time to grow as it would be colder. Magma would be spread at least 50 kilometres into the atmosphere.

Volcanoes are one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 are expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable.
The movie showed many warning signs that actually occur before a volcanic eruption, but they were a bit exaggerated. A hot spring is shown in the movie as a warning sign, which is a result of the magma moving toward the surface. In the beginning of the movie it shows that two people swimming in a hot spring, and after a couple minutes the temperature suddenly changed and they were burned alive. Temperature changes can definitely occur, so that is accurate. Although the temperature usually does change, it can take days or weeks to develop, rather than a few seconds as shown in the movie. Carb...
This essay will explain just that. Volcano monitoring can save lives. This can be made possible via an active warning system to potential eruptions. With this we can give local residents an early warning to vacate the area. This will theoretically save hundreds from a toasty death.
Many people still today live near very dangerous volcanoes. This is because the se people believe that an eruption is not so much of a threat, compared to the benefits they acquire. Evidence: Today, about 500 million people live on or close to volcanoes. One such example is: Mount Vesuvius in Naples, Italy.
When a volcano erupts, the focus is particularly on the consequences that take place near the volcano, such as weather conditions, the impact on nature, and the people who are affected. The noticeable changes that take place after a volcanic eruption includes the decrease in the temperature, natural disasters, such as tsunamis, droughts, and hurricanes, and the air pollution, which can be harmful to plants, animals, and people.
