Arias intensity
text:
The Arias intensity (IA) is a measure of the strength of a ground motion. It determines the intensity of shaking by measuring the acceleration of transient seismic waves. It has been found to be a fairly reliable parameter to describe earthquake shaking necessary to trigger landslides. It was proposed by Chilean engineer Arturo Arias in 1970. It is defined as the time-integral of the square of the ground acceleration: where g is the acceleration due to gravity and Td is the duration of signal ab
