What is the earthquake scale called.
How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter.
People have always tried to quantify the size of and damage done by earthquakes. Since early in the 20th century, there have been three methods The oldest of the scales is called the Mercalli Intensity scale. Earthquakes are described in terms of what nearby residents felt and the damage that was done to nearby structures.Study with Quizlet and memorize flashcards containing terms like A large ocean wave that is generated by vertical motions of the seafloor during an earthquake is called a(n) __________.
