Prediction of Earthquake Losses
Earthquake loss estimation is usually defined as a Damage Ratio (DR) which is a ratio of the earthquake damage repair cost to the total value of a building. Probable Maximum Loss (PML) is a common term used for earthquake loss estimation, but it lacks a precise definition. In 1999, ASTM E2026 'Standard Guide for the Estimation of Building Damageability in Earthquakes' was produced in order to standardize the nomenclature for seismic loss estimation, as well as establish guidelines as to the review process and qualifications of the reviewer.
Earthquake loss estimations are also referred to as Seismic Risk Assessments. The risk assessment process generally involves determining the probability of various ground motions coupled with the vulnerability or damage of the building under those ground motions. The results are defined as a percent of building replacement value.

Famous quotes containing the words prediction of, prediction, earthquake and/or losses:
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)

“Through the din and desultoriness of noon, even in the most Oriental city, is seen the fresh and primitive and savage nature, in which Scythians and Ethiopians and Indians dwell. What is echo, what are light and shade, day and night, ocean and stars, earthquake and eclipse, there? The works of man are everywhere swallowed up in the immensity of nature. The AEgean Sea is but Lake Huron still to the Indian.”
—Henry David Thoreau (1817–1862)
“Hold back thy hours, dark Night, till we have done;
The Day will come too soon.
Young maids will curse thee, if thou steal’st away
And leav’st their losses open to the day.
Stay, stay, and hide
The blushes of the bride.”
—Francis Beaumont (1584-1616)
