Intensity is measured on the Modified Mercalli Scale. This is a scale that is based on effects observed from the earthquake and to what degree those effects are felt. It ranges on a scale from 1 to 12, one being the lowest effects and 12 being total loss. Negative: Tsunami and Flooding. Earthquakes can also cause tsunamis, which in turn cause massive flooding in coastal areas. When a strong earthquake occurs underwater, it changes the level of the seabed and causes the water level to either rise or fall. Whether it rises or falls, it is a danger to coastal areas because of the creation of …A simple seismometer, sensitive to up-down motions of the Earth, is like a weight hanging from a spring, both suspended from a frame that moves along with any motion detected.
