7 Natural Disasters That Might Happen in the Next Years

number one the lake toba super volcano it happened 74 000 years ago and it was one of the earth's largest explosive eruptions it caused a global winter that lasted for years volcanic gases were ejected into both hemispheres and moved all around the planet the eruption created the famous lake toba which covers an area of 436 square miles the topo volcano is still active and if a similar eruption happens again it will directly affect both indonesia and malaysia but toba could also pump out enough gas to affect the whole world's climate and just like last time there will be cooler temperatures increased amounts of ice and a lot more snow countries and regions from northwestern australia to east africa might experience tsunamis the world's economy could be damaged plant life would struggle and travel would be paralyzed if the volcano reawakens the only solution would be a mass evacuation number two the helena slump the possible collapse of the southern portion of the kilauea volcano on the big island of hawaii is a real danger this area is called the helena slump and it could drop 2 900 cubic miles of rock into the pacific ocean that could generate a mega tsunami that would spread around the pacific and reach the western coast of north america in just a few hours 120 000 years ago a similar collapse occurred near mauna loa in hawaii it caused a tsunami with waves as high as the taipei skyscraper one of the world's tallest buildings right now the slump is becoming deformed faster than any other oceanic island slump in the world pushed along by magma it moves four inches per year toward the sea but geologists believe that a mega tsunami is unlikely to happen soon because the slump is reinforced on some narrow land that prevents it from detaching from the volcano number three a north sea tsunami more than 6200 years ago the climate started getting warmer and it caused ice to melt and the sea levels to rise this made the underwater sediment around the edge of norway much heavier and this caused a 180 mile long coastal shelf to collapse this event is known as the three storega slides which scientists think were among the largest submarine landslides to have ever occurred when the shelf collapsed it caused a mega tsunami in the north atlantic ocean two things could have caused the collapse one was a possible earthquake which triggered an expansion of fire eyes these are deposits of ice containing methane molecules and they usually appear at the bottom of the sea or it could be that ice carried trillions of tons of solid material to the edge of the coastal shelf where it melted then there was an earthquake which caused a large area of the sea floor to collapse deeper into the sea the wave was felt beyond the shores of scotland and even went as far as greenland the result is the ormond lounge a natural gas field on the norwegian continental shelf but some scientists believe that a similar event could only occur after a new ice age while others think that there's no significant risk of a new landslide happening at all number four the cascadian trench big one at the bottom of the pacific ocean off the west coast of north america there's a subduction zone that's when two tectonic plates meet and one starts to bend and slide below the other the cascadian trench runs from northern california to vancouver island in this case the oceanic floor is being forced beneath the north american land mass the floor moves around 1.6 inches per year but the upper part of the system is stuck and now the north american plate is compressed the pressure keeps building up there and it needs to be released it might happen in the form of a magnitude 9 earthquake this might cause the coast to sink by six and a half feet and could make it move horizontally and after the earthquake tails off the coast could experience a tsunami similar to the wave that hit japan in 2011. scientists have calculated that in the last 10 000 years the area has experienced 41 large earthquakes the last magnitude 9 tremor occurred in january 1700 experts currently believe there's a 37 percent chance that a 7.1 magnitude tremor will occur in the next 50 years number five the sun's big one luckily for us one of the worst solar flares ever recorded happened when our civilization wasn't vulnerable to the fury of the sun it's known as the carrington event it happened in september 1859 long before the development of modern technology a huge wave of plasma and magnetic field washed over the earth's own protective magnetic layer this produced an enormous solar storm this led to intense auroras that lit up the skies but aside from the pretty lights the strong electrical currents that came with the storm had major consequences the telegraph communication systems covering both europe and north america went down fires blade and disconnected power supplies kept relaying their eerie messages in 1989 another bad solar storm struck the earth the most extreme results were seen in quebec canada the power grid went totally offline and six million people were left without electricity since solar flares happen often some scientists predict that another powerful storm will occur soon they've named it the big one big solar storms like this happen only once every 500 years scientists believe it'll be powerful enough to knock out electrical and communication systems around the world for days months or even years number six a new asteroid impact once every few million years an object appears from space that's large enough to threaten civilization the asteroid or comet that wiped out the dinosaurs was about seven to fifty miles in diameter if a similar rock comes along again then this is what would happen first the impact might cause a tsunami although this depends on whether the rock falls into the middle of the ocean or on dry land a cloud of hot dust ash and steam will spread out from the impact crater debris and pieces of the asteroid will be thrown out of the atmosphere by the blast they'll be heated by radiation and if they fall back to earth they could ignite wildfires the shock from the impact will meanwhile trigger global earthquakes and volcanic eruptions dust and other particles could cover the planet's surface for years creating a harsh environment that would be difficult to survive in to prepare for this scenario some scientists are designing a conceptual asteroid deflector the idea is to send explosives out to the asteroid this would destroy parts of its surface and hopefully change its orbit number 7 yellowstone volcano located underneath yellowstone national park in the u.s the yellowstone super volcano is one of the most actively monitored places on the planet it's experienced three super eruptions in the past two million years the last one occurred 640 thousand years ago i wasn't around that and created a sunken giant crater with an area of 1500 square miles if it erupts again the consequences could be worse than the toba event because most of the ash will fall onto land instead of in the sea the last eruption spread volcanic ash across both american continents all vegetation might cease to exist and animals could end up breathing in toxic chemicals the ground would become brighter and incoming radiation would reflect back into the atmosphere this could cause a lengthy drought water supplies would become blocked up electricity lines would fail and there would be major disruptions to transport gee i think it's time to stock up on toilet paper
