The report – Seismic fragility formulations for water systems – has been prepared by the American Lifelines Alliance (ALA), a public-private partnership between the Federal Emergency Management Agency and the American Society of Civil Engineers.

“The use of these fragility data will allow water system owners to make consistent estimates of the vulnerability of their systems and make informed decisions to mitigate their risks,” said Craig Wingo, director of the Federal Emergency Management Agency’s National Earthquake Program Office.
