Abstract:<\/span>
Earthquake induced landslides \u2013 lessons from Taiwan and Pakistan<\/span><\/span><\/span><\/b><\/p>\n

<\/div>\n

The recent Wenchuan<\/span> earthquake in Sichuan<\/span> Province of China has highlighted the impact of seismically-triggered landslides in mountain environments. <\/span>In China, it is now estimated that approximately 28,000 fatalities, representing about 35% of the deaths in the earthquake, occurred as a result of burial by mass movements. <\/span>In addition, the blockage of all of the mountain roads by landslides meant that rescue of buried victims in the so-called \u201cgolden\u201d 24 hours was seriously impeded, and more than 150 rescuers were subsequent killed by slides triggered by aftershocks. <\/span>This presentation seeks to examine the occurrence of landslides in two other major seismic events, namely the 1999 Chi-Chi earthquake in Taiwan and the 2005 Kashmir earthquake in Pakistan. <\/span>Using field data from both sites, the occurrence of landslides induced by the earthquake is examined in both space and time. <\/span>It is shown that the distributions of landslides are rather different in the two cases, even though they earthquakes themselves were of similar magnitudes. <\/span>The reasons for this difference are explored, in particular in relation to topographic controls on the magnitude of earthquake accelerations on slopes. <\/p>\n

In the second part of the presentation, the occurrence of landslides in the years following the earthquakes is explored. <\/span>It is shown that there is a notable increase in the occurrence of landslides in the aftermath of the seismic event, and that these landslides release large volumes of sediment into the river system. <\/span>This increase in landslide activity can have a major impact on the rehabilitation of earthquake-affected areas for long periods of time. <\/span>Thus, there is a need to improve preparation for earthquakes in landslide-prone areas and to recognise that the impacts of such events are prolonged, rendering the recovery phase rather difficult from an engineering perspective.<\/p>\n","protected":false},"excerpt":{"rendered":"
