Sherif Saber ‫ال‬ ‫ﻫﻰ‬ ‫ﻣﺎ‬ Directivity ‫؟‬ ‫ال‬ ‫ﻣﺎﻫﻰ‬ ‫و‬ Directionality ‫؟‬ ӵӷ Rupture generally progresses across a fault as a series of dislocations (some multiple-event earthquakes can be thought of as a series of small earthquakes that occur in close spatial and temporal proximity). Small earthquakes can be modeled as point processes since their rupture surfaces usually span only a few kilometers. Large earthquakes, however, can rupture over distances of tens, or even hundreds, of kilometers, and the nature of ground shaking can be influenced by the characteristics of the rupture process. For example, waves emanate from the fault with different strengths in different directions; such directivity effects can produce azimuthal differences in ground motion characteristics (Benioff, 1955; Ben-Menachem, 1961). Constructive interference of waves produced by successive dislocations can produce strong pulses of large displacement Sherif Saber

Kramer 1.3.6 Lifeline Hazards A network of facilities that provide the services required for commerce and public health can be found in virtually any developed area. These networks, which include electrical power and telecommunications, transportation, water and sewage, oil and gas distribution, and waste storage systems, have collectively come to be known as lifelines. Lifeline systems may include power plants, transmission towers, and buried electrical cables, roads, bridges, harbors, and airports, water treatment facilities, reservoirs and elevated water tanks, and buried water distribution systems; liquid storage tanks and buried oil and gas pipelines; and municipal solid waste and hazardous waste landfills Sherif Saber
