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
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.

On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east! This explosion was the most powerful in a series of eruptions from 1914 through 1917. ...
...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.
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.
The eruption on Mount Saint Helens has a specific cause and comes with many effects. A multifold of people would say that the “mountain looked like the site of an atomic blast” (Bredeson 30). That is a very accurate depiction as it took great power to inflict as much damage as it did. The reason for this impressive amount of force is that when magma is built up with pressure and an earthquake hits, the pressure gets magnified and the volcano explodes (Lewis). This is exactly what happened inside Mount Saint Helens. Furthermore, it has been revealed that “The earthquake that triggered the explosion was a 5.2 on the Richter scale” (Gunn 559). The earthquake to the magma can be compared as a match to gasoline. Even though the earthquake was not huge, the scale of the eruption was much greater than that of the earthquake (Gunn 560). The earthquake was only the trigger that allowed for more devastating things to occur. Thirteen hundred feet of the volcano were lost in the explosion followed by landslides, mudslides, and lava flows...
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 be one of the most destructive forces on Earth. It is estimated that some
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...
V-Lab Debationator Lewis I believe that we should pay for volcano monitoring. It could potentially save lives, it might even save yours. Volcano monitoring can be revolutionized into possibly a non-funded project. If volcanoes were monitored, then casualties and deaths would be minimized.
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...
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.
There are other short-term effects, and these effects don’t just take place in the area of an eruption, but expands to other parts of the world. Globally, what has become an issue of its own is climate change. In the Encyclopedia Britannica, Jackson (2013) defined climate change as a “periodic modification of Earth's climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth system.” With all of the debris that enters the atmosphere from eruptions, volcanoes can make an impact on climate change. Volcanic activity can cause global cooling, but some sources say that it has the potential to impact global warming as well, due to the amount of carbon dioxide (CO...
Hence, our focus should be placed on lessening the severity of the impact they have on every aspect of our lives. We can successfully reduce their damaging effects by implementing effective monitoring and warning systems, building codes, flood defences, comprehensive disaster management plans and educating citizens on disaster preparedness. The best way to minimise the effects of a natural disaster is to establish early detection systems that allow for advance warning to be given to national and global communities. Sophisticated seismic monitoring networks can identify significant movements of the earth’s crust, therefore providing early notification of an imminent volcanic eruption. Close examination of the boundaries between tectonic plates can indicate the build-up and intensification of tension at convergent plate boundaries.
