Earthquake intensity level calculator
WebThe basic equation for magnitude and intensity is M = log (I/S) or magnitude is the base ten logarithm of intensity over standard. Applying some algebra and rules of logarithms, Intensity can be isolated M = log (I/S) 10^M = 10^ (Log (I/S)) 10^M = I/S I = (10^M) * S If M = log (I/S) and I = S then M = log (I/S) = log (1) = 0 because 10^0 = 1. WebDec 22, 2024 · Sound intensity level (SIL) is defined as the sound wave power per unit area. This quantity allows us to measure the energy of sound (or, to be more precise, the energy per second per one squared meter). The formula is: SIL = 10 × log (I/Iref) where: SIL – Sound intensity level in dB; I – Sound intensity in watts per squared meter; and

WebIf you know how rapidly intensity decreases as a function of distance from the epicentre (i.e. you have an attenuation law) then you can calculate how far away a magnitude 5.5 earthquake can be from the site and still generate at least intensity 6 at the site itself. Let's say the value is 30 km. Draw a circle 30 km radius round the site. WebOct 11, 2013 · Traditionally, scientists have looked at the earthquake itself—using location, magnitude, and depth—to estimate the size and direction of the tsunami. As an oceanographer, Song knew that historic records had proven this method did not always …
WebJul 5, 2024 · There are two commonly-used scales to rate earthquakes 1) the Richter Scale and 2) the Mercalli Scale. The force at which an earthquake shakes the ground is measured with the Richter Scale, which rates the earthquake's actual force on a scale from 0 to 9. WebAn earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. In the United States, we use the Modified Mercalli (MMI) Scale.
