On April 25, Nepal was devastated by a massive earthquake measuring 7.8 on the richter scale...The magnitude scale is really measuring the physical size of the earthquake, not the STRENGTH (energy) of the quakes. So, a magnitude 8.7 is 794 times bigger than a 5.8 quake as measured on seismograms, but the 8.7 quake is about 23,000 times STRONGER than the 5.8!

According to the joint damage rating established by the European macroseismic scale (EMS-98), the building damage was divided into four categories. What’s the difference between geologic hazard and risk? Geologic hazards are naturally-occurring phenomena capable of causing loss or damage. Risk is the potential that exposure to the hazard will lead to a negative consequence such as loss of life or economic loss.To illustrate the difference, consider the following two examples. California …Mercalli Intensity Scale. Earthquakes are described in terms of what nearby residents felt and the damage that was done to nearby structures. Richter magnitude scale.
