- Seismic vulnerability of buried pipelines Raúl Flores Berrones Xiangyue Li Liu Ciencias de la Tierra pipelines water supply Earthquake damage Earthquakes may cause severe damage to buried pipelines. One dramatic example occurred during the Michoacán earthquakesof September 1985. Many aqueducts and pipelines in Mexico City and in Lázaro Cárdenas failed as a result of thoseearthquakes. Similar damages were also observed more recently in the earthquakes in Loma Prieta (Marina District), in 1989; inNorthridge, California in 1994; and in Kobe, Japan, in 1995.This paper illustrates the kind of problems that take place after the failure of pipelines conducting water, gas or sewage. Italso gives the principal causes of those failures, and the methods available today to take into consideration seismic effects for theproper design of buried pipelines. Some simplified procedures for preventing effects due to permanent ground deformation andseismic wave propagation on continuous and segmented pipelines are given, together with some recommendations to be followedwhen installing buried pipelines in seismic areas. 2003 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56842208 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.42
