State-of-the-Art for Assessing Earthquake Hazards in the United States: Report 19, The Evidence for Reservoir-Induced Macroearthquakes

Partial abstract: "The published evidence of reservoir-induced macroearthquakes is critically reviewed. The evidence is partitioned into three types: (a) evidence of a post-impoundment increase in seismicity, (b) correlation evidence that is composed of a plot of a reservoir variable and a seismicity variable and, in most cases, an auxiliary variable, time, and (c) evidence based on the slope of the magnitude-frequency relationship (b value evidence)."

Mission Bay Harbor, California, Design for Wave and Surge Protection and Flood Control: Hydraulic Model Investigation (open access)

Mission Bay Harbor, California, Design for Wave and Surge Protection and Flood Control: Hydraulic Model Investigation

Partial abstract: A 1:100-scale (undistorted) hydraulic model, reproducing Mission Bay Harbor, approximately 3 miles of shoreline, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed structures for (a) improving hazardous entrance conditions, (b) reducing surge inside the harbor, and (c) eliminating potential flood hazards. The original proposal for harbor improvement consisted of a 2,200-ft-long offshore breakwater. The proposed structures for river flood control consisted of (a) a 1,200-ft-long weir in the middle jetty, (b) various south jetty extensions, and (c) diversion dikes on the middle jetty.

The Vaiont Slide: A Geotechnical Analysis Based on New Geologic Observations of the Failure Surface, Volume 1: Main Text (open access)

The Vaiont Slide: A Geotechnical Analysis Based on New Geologic Observations of the Failure Surface, Volume 1: Main Text

First part of a final report describing "efforts to confirm the existence and nature of clay seams in the [Vaiont Slide] mass and to confirm the possible existence of an 'old' slide at the site. These efforts were made by (a) firsthand field observations of the geology, (b) an examination of preslide and postslide airphotographs, (c) laboratory testing of samples of failure plane materials, and (d) and examination and translation of geologic and other documents related to preslide and postslide conditions" (abstract, para. 2). The report also presents stability analyses of the Vaiont Slide.
