The main event triggered tsunami waves that damaged structures along the coast, while the surface ground motion induced localized liquefaction, settlement of bridge abutments, rockfall, debris flow, and collapse in several adobe structures. Because of the strict seismic codes in Chile, damage to modern engineered infrastructure was limited, although there was widespread tsunami\u2010induced damage to one\u2010story and two\u2010stories residential homes adjacent to the shoreline. Soon after the earthquake, shear wave measurements were performed at selected potentially liquefiable sites to test recent\n                    <jats:italic>V<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>S<\/jats:italic>\n                    <\/jats:sub>\n                    \u2010based liquefaction susceptibility approaches. This paper describes the effects that this earthquake sequence and tsunami had on a number of retaining structures, bridge abutments, and cuts along Chile's main highway (Route 5). Since tsunami waves redistribute coastal and near shore sand along the coast, liquefaction evidence in coastal zones with tsunami waves is sometimes obscured within minutes because the tsunami waves entrain and deposit sand that covers or erodes evidence of liquefaction (e.g., lateral spread or sand blows). This suggests that liquefaction occurrence and hazard may be under estimated in coastal zones. Importantly, the areas that experienced the greatest coseismic slip, appeared to have the largest volumes of rockfall that impacted roads, which suggests that coseismic slip maps, generated immediately after the shaking stops, can provide a first order indication about where to expect damage during future major events.\n                  <\/jats:p>","DOI":"10.1193\/031716eqs043m","type":"journal-article","created":{"date-parts":[[2017,1,31]],"date-time":"2017-01-31T12:45:34Z","timestamp":1485866734000},"page":"709-728","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Geotechnical Aspects of the 2015\u00a0M\n                    <sub>w<\/sub>\n                    8.3 Illapel Megathrust Earthquake Sequence in Chile"],"prefix":"10.1002","volume":"33","author":[{"given":"Gabriel","family":"Candia","sequence":"first","affiliation":[{"name":"Facultad de Ingenier\u00eda Civil Universidad del Desarrollo Av.
