“…The seismic risk results obtained from the assessment outlined above have been used in different activities that include: the design of cross (subsidized) collective earthquake insurance schemes, the development of hybrid loss exceedance curves (Velásquez et al 2014), the feasibility assessment of the use of alternative risk transfer instruments such as captive or cat-bonds for the insurance of the water and sewage network components, as well as the identification of the best materials and characteristics for the construction, maintenance, expansion, and update of pipelines.…”

A fully probabilistic seismic risk assessment was developed in Manizales, Colombia, considering assets of different types. The first type includes elements that are part of the water and sewage network, and the second type includes public and private buildings. This assessment required the development of a probabilistic seismic hazard analysis that accounts for the dynamic soil response, assembling high resolution exposure databases, and the development of damage models for different types of elements. The economic appraisal of the exposed assets was developed together with specialists of the water utilities company of Manizales and the city administration. The risk assessment was performed using several Comprehensive Approach to Probabilistic Risk Assessment modules as well as the R-System, obtaining results in terms of traditional metrics such as loss exceedance curve, average annual loss, and probable maximum loss. For the case of pipelines, repair rates were also estimated. The results for the water and sewage network were used in activities related to the expansion and maintenance strategies, as well as for the exploration of financial retention and transfer alternatives using insurance schemes based on technical, probabilistic, and prospective damage and loss estimations.In the case of the buildings, the results were used in the update of the technical premium values of the existing collective insurance scheme.

“…Even though the expected losses associated with the occurrence of a single landslide are relatively small, when compared to those expected for hazards of larger consequences such as earthquakes, their high recurrence rate makes them of great importance when managing disaster risk at a regional or local level, since there can be an important accumulation of losses over time (Marulanda et al 2008(Marulanda et al , 2010(Marulanda et al , 2011Velásquez et al 2014).…”

The details of a multi-hazard and probabilistic risk assessment, developed for urban planning and emergency response activities in Manizales, Colombia, are presented in this article. This risk assessment effort was developed under the framework of an integral disaster risk management project whose goal was to connect risk reduction activities by using open access and state-of-theart risk models. A probabilistic approach was used for the analysis of seismic, landslide, and volcanic hazards to obtain stochastic event sets suitable for probabilistic loss estimation and to generate risk results in different metrics after aggregating in a rigorous way the losses associated to the different hazards. Detailed and high resolution exposure databases were used for the building stock and infrastructure of the city together with a set of vulnerability functions for each of the perils considered. The urban and territorial ordering plan of the city was updated for socioeconomic development and land use using the hazard and risk inputs and determinants, which cover not only the current urban area but also those adjacent areas where the expansion of Manizales is expected to occur. The emergency response capabilities of the city were improved by taking into account risk scenarios and after updating an automatic and real-time post-earthquake damage assessment.

“…In addition the EM-DAT, does not report any natural disaster in Portugal for the period 1900-1967. At this global level we may also refer to databases such as NatCat (Münich Reinsurance Company), Sigma (Swiss Reinsurance Company) and Disaster Inventory System -DesInventar [13]. Several countries also benefit from national databases, such as Great Britain [14], Switzerland [3], Italy [11], Australia [15], the United States of America [16] and Canada [17].…”

Floods and landslides are the natural hazards that most affect Northern Portugal. This paper presents the DISASTER database results for Northern Portugal, containing occurrences of floods and landslides between 1865 and 2010. The research carried out was based on press articles published in national and regional newspapers, but focusing exclusively the occurrences that caused personal damage, including deaths, injured, missing, evacuees and displaced people, regardless of the number of people affected and the economic value of damages. A total of 613 occurrences were recorded, which 18% are landslides and 82% are floods. These occurrences were responsible for 198 deaths, 58 injured, 34 disappeared, 1804 evacuated and 15,918 displaced. The trend analysis shows an increase of 0.17 occurrences/decade. The obtained results show the occurrences concentration in the more urbanized areas and along larger rivers.
