In your home, determine the objects that could become a hazard during an earthquake, such as pictures, mirrors, lamps, hanging flower pots, etc. Unlike hurricanes, earthquakes effects are not predictable. Earthquakes are natural phenomena that happen suddenly, without warning. There are continuous earthquakes today in the world and earthquakes happen when you least expect it. Here you can see another interesting Interactive 3D Maps here: These explosions are so strong that they can impact the tectonic plates and transmit vibrations that cause small earthquakes. Atomic weapons testing is so destructive that it must be done far from human and wildlife, which is why it is often carried out underground. There is debate about the possibility that hydraulic fracturing or fracking methods, consisting of the injection of water and chemical materials into hydrocarbon wells to increase or promote the extraction of valuable matter, may increase the seismic instability of the area and cause earthquakes. The human hand can also accidentally cause tremors, as occurs with the microseisms that often occur when cold water is injected into geothermal reservoirs, where the earth’s own heat makes the liquid boil and produces geysers.įracking. This can also occur in the presence of volcanic activity. Earth’s tectonic plates move below the surface, over magma, and often collide with each other, generating seismic waves that bounce back to the surface. A tremor can respond to various causes, natural and of human origin:
