Topic 14. Lessons learned from extreme natural events: how experience improves resilience

  • IP0295 - Actions in infrastructures after the volcanic eruption on the island of La Palma.

    On September 19, 2021, the beginning of an important Strombolian fissural volcanic episode of magnitude 3 in the volcanic explosivity index (IEV) took place on the island of La Palma, which for 85 days caused damage to infrastructures, agriculture and the environment. The LP-2, LP-211, LP-212, LP-213 and LP-2132 highways, which connected the towns of Puerto Naos, Todoque and Tazacorte, were buried [...]

  • IP0100 - Budget Approximation for Optimal Highway Network Retrofit Problem

    Transportation network is a backbone infrastructure. Disruption to the transportation network will cause commotions and adverse effects on economic and social activities. In the second half of 2011, Thailand had faced with the most devastating flood of her modern history. Some roads were heavily destroyed while others were partially damaged and emergency relieves could not access to the flooded areas. [...]

  • IP0028 - Damage, Effects and Lessons Learned in the Construction of the Oyon Ambo Road in the High Andean Area of Peru During El Niño in 2019
    Victor Andre ARIZA FLORES

    In Peru, during the months of January to March 2019, the Peruvian highlands experienced the consequences of the El Niño phenomenon, a natural event characterized by the fluctuation of ocean temperatures in the central and eastern part of the equatorial Pacific, associated with changes in the atmosphere. The main affected sectors correspond to the high Andean areas and the jungle of Peru where rainfall [...]

  • IP0411 - Experience Improves Resilience

    Colombia, a South American country whose geographical location is privileged given its maritime area in the Atlantic and Pacific oceans with its comparative and competitive advantages. However, this geographical position exposes it to threats that had not been contemplated, such as Tropical Cyclones; this perhaps, due to ignorance of the probability of occurrence of this type of event on the territory. [...]

  • IP0469 - Operating a Major Road at the A83 Rest and be Thankful Landslide Site
    George FIDDES

    Landslides in the form of fast-moving debris flow are known to have occurred at the A83 Rest and be Thankful site in the west of Scotland since the early part of the last century. However, in 2004 a series of major events caused severe disruption to the major road network. While the Rest and be Thankful site was not affected in 2004, subsequent events in 2007 and in many years since have taken the [...]

  • IP0599 - Operationalizing systemic criticality and physical vulnerability for road infrastructure hazard risk analysis: Lessons learned from resilience interventions in South Asia

    Vulnerability and criticality are component-level and network-level characteristics of a road asset, respectively, and essential for understanding risk. However, in the road asset management practice and at the operational level, they have not yet been employed at full capacity. Vulnerability, criticality, and risk are constructed versatile concepts, originating from separated domains with terminological [...]

  • IP0171 - Post-Disaster Infrastructure Recovery in Central Sulawesi, Indonesia
    Miftachul MUNIR

    Palu, the capital city of Central Sulawesi Province in Indonesia, was struck by a 7,5-magnitude earthquake disaster on September 28, 2018. The main earthquake damage was caused by liquefaction, landslides, tsunamis, and seismic activity in coastal areas. The collapse of bridges, damage to port facilities, water supply facilities, and disruption of public facilities were mainly observed in Palu City, [...]

  • IP0514 - Slope Instability Analysis In Fissured Clay Shales at Sumedang National Road
    Aldiamar FAHMI - Member of PIARC TC 1.5

    Based on the regional geological conditions, National Roads in Sumedang, West Java, Indonesia, were constructed over the Subang Formation which is a claystone member that contained beds of hard marly limestone, marl, and dark grey limestone. Several publications indicated that Subang Formation was well known as clay shale material that consists of 4.40 – 10.40 % of montmorillonite and 16.90 – [...]
