What is the difference between the mercalli scale and the seismometer?
Not the same. Read below. Earthquakes are measured by their intensity and magnitude. An earthquake’s intensity readings are based on observed effects, for example, ground shaking and damage. An earthquake’s intensity differs in separate locations, depending on the distance of the location from the earthquake’s epicenter. The ranking system used to measure seismic intensity is called the Mercalli Scale. Michele Stefano de Rossi and FranÇois to Alphonse Forel formulated the Mercalli Scale in 1878. Harry O. Wood and Frank Neumann modified it in 1931. An earthquake’s magnitude reading is based on the amount of seismic energy released at the hypocenter of the earthquake. It is based on the magnitude of the earthquake waves. The ranking system used to measure earthquake magnitudes is called the Richter scale. Seismometer are used by seismologists to measure and record seismic waves. ————————————–… studying seismic waves, geologists can map the interior of the Earth,
