Che cosa è la scala Richter?
La Magnitudo del terremoto Richter come misura oggettiva della quantità di energia elastica emessa durante il terremoto. Esprime la grandezza di un terremoto attraverso la misura dell'ampiezza massima della traccia registrata dal sismografo.
Che differenza c'è tra scala Mercalli e scala Richter?
Mentre la scala Richter misura la magnitudo di un terremoto, quindi la quantità di energia rilasciata, la scala Mercalli valuta l'intensità del sisma, basandosi sui danni arrecati alle strutture umane e allo sconvolgimento del suolo.
What is the Richter scale and what does it measure?
- The Richter scale, officially called the "Richter Magnitude Scale," is a numerical value used to measure the power of earthquakes. It is a logarithmic scale based on the amplitude of waves recorded by a seismograph. This means that each whole number increase on the scale corresponds to an absolute increase by a factor of ten.
How many levels are there on the Richter scale?
- The Richter Scale measures earthquakes by using seven different categories: micro, minor, light, moderate, strong, major, and great. Below is a look at each description: Micro earthquakes are measured at between 1 and 1.9. This magnitude would be considered a I on the Mercalli intensity scale.
What do the numbers on the Richter scale represent?
- The Richter scale is a standard scale used to compare earthquakes. It is a logarithmic scale, meaning that the numbers on the scale measure factors of 10. So, for example, an earthquake that measures 4.0 on the Richter scale is 10 times larger than one that measures 3.0.
How to calculate Richter scale?
- The original Richter scale formula, that is used to calculate the magnitude of any earthquake, is as follows: M L = log 10 A – log 10 A 0 (δ) where, M L is the magnitude, A is the maximum excursion or the greatest deviation on the Wood-Anderson seismograph , and A 0 depends on the distance between the seismic station and epicenter (δ).
