Obscure Disasters Can Pose Major Risks

Disasters come in all shapes and sizes. Make sure you're prepared!

With the Japan earthquake, frequent hurricanes, and massive tornadoes, many are wondering if we should expect more and bigger disasters. Major disasters by their very nature are unpredictable, which further enforces the need to imagine worst-case scenarios when implementing or rehearsing disaster response efforts.

The effect of some disasters, such as floods and hurricanes, can be minimized by advanced planning. For instance, governments can build levees and coastal swamp areas can be left undeveloped to provide natural flood protection. If the origins of a disaster come from beyond our planet or miles under the surface, then prevention is impossible, and preparation and planning are the only possible means of recourse.

Solar Flares are a known sun phenomena that affect communications on earth. In the past, such interruptions were temporary and were limited to certain types of devices and services. However, scientists who study solar storm patterns now contend that the severity of storms is cyclical and we are now entering an intense phase.

  • NASA officials have equated a large solar storm to a “bolt of lightning” that could damage electronics and communications’ equipment around the globe.
  • Solar flares dramatically change the earth’s magnetic field, which could cause serious consequences for satellites, computers, handheld devices and myriad other items.
  • If international power grids fail, potential losses are estimated to be in the trillions.
  • Solar storms are monitored by the appropriately named Space Weather Prediction Center, which is run by the National Oceanic and Atmospheric Administration.

 

Disasters come in all shapes and sizes. Make sure you’re prepared for each type. On the west coast, scientists are concerned about what they refer to as an ARKstorm, a massive storm that dumps rain on California, Oregon, Washington, and Nevada for up to two weeks straight. The storms pull so much heat and moisture, that they develop “atmospheric rivers.” Such rainfall amounts would produce massive flooding in the California central valley and in major metropolitan areas. It would simply be a case of too much water with nowhere to go.

  • Such a storm is based upon historical precedent, with winter rains in 1861 and 1862 leaving some parts of central California completely impassable. In San Francisco, nearly 30 inches of rain was reported.
  • The USGS offers a video titled “This is ARKstorm” that some might consider to be a little over the top. But it does clearly describe the possible effects.
  • Projected damage estimates are pegged at several hundred billion dollars.

Yellowstone Caldera” might sound like the latest trendy micro-brew. But it actually refers to a potential “super volcano” that could erupt in Yellowstone National Park. Yellowstone sits on a “hotspot,” which is an area where molten mantle rock moves towards the surface over time. As it moves closer, it can become trapped, and needs release of pressure to prevent catastrophic explosions.

  • The latest eruption occurred only 640,000 years ago, which is a very long time compared to a human lifetime, but a relatively recent event geologically speaking.
  • Half of the United States could be covered in ash.
  • Global cooling would result from atmospheric sun-blocking particles, restricting agriculture and leading to food shortages.

The existence of such mega-disasters underscores the broader point of knowing there are various risks and that it is necessary to do your best to plan ahead and prepare for unforeseen contingencies. While you certainly shouldn’t live your life in a potential state of abject fear, it is important to take time to consider the unknown.
