There are almost 50 years of research on fragility and vulnerability assessment, both key elements in seismic risk or loss estimation. This paper presents the online database physical models that has been created as part Global Earthquake Model (GEM) initiative. The comprises curves, damage-to-loss models, capacity curves for various types structures. attributes have selected to characterize each function, constraints setting up a usable database, challenges collecting these current trends...
Tsunamis are destructive natural phenomena which cause extensive damage to the built environment, affecting livelihoods and economy of impacted nations. This has been demonstrated by tragic events Indian Ocean tsunami in 2004, or Great East Japan 2011. Following such events, a few studies have attempted assess fragility existing building inventory constructing empirical stochastic functions, relate measure intensity. However, these typically fit linear statistical model available data,...
Tsunami fragility curves are statistical models which form a key component of tsunami risk models, as they provide probabilistic link between intensity measure (TIM) and building damage. Existing studies apply different TIMs (e.g. depth, velocity, force etc.) with conflicting recommendations to use. This paper presents rigorous methodology using advanced methods for the selection optimal TIM function derivation any given dataset. is demonstrated unique, detailed, disaggregated damage dataset...
Abstract. The insurance of green economy assets against natural hazards is a growing market. This study explores whether currently available published knowledge adequate for the vulnerability assessment these to hazards. A matrix constructed demonstrate functional loss 37 asset classes in renewable energy, construction, resource management, carbon capture and storage, energy sustainable transportation sectors. 28 adopted range from environmental geophysical events oceanic, coastal, space...
Empirical fragility curves, constructed from databases of thousands building-damage observations, are commonly used for earthquake risk assessments, particularly in Europe and Japan, where building stocks often difficult to model analytically (e.g. old masonry structures or timber dwellings). Curves different studies, however, display considerable differences, which lead high uncertainty the assessed seismic risk. One potential reason this dispersion is almost universal neglect spatial...
Despite indoor mould being one of the most common problems in residential properties UK, there are not any widely accepted methodologies for its measurement. This paper focusses on this problem measurement and reports findings from a rigorous testing scheme carried out to quantify air surface concentrations particle counts within 71 rooms 64 North London, some with without visible mould. The aim was investigate potential passive active sampling strategies (sampling still actively mixed air,...
Background Provision of donor human milk is handled by established banks that implement all required measures to ensure its safety and quality. Detailed banking guidelines on a European level are currently lacking, while the information available actual practices followed banks, remains limited. The aim this study was collect detailed data across Europe with particular emphasis affecting quality milk. Materials methods A web-based questionnaire developed Milk Bank Association (EMBA) Survey...
Abstract. Indonesia has experienced several tsunamis triggered by seismic and non-seismic (i.e., landslides) sources. These events damaged or destroyed coastal buildings infrastructure caused considerable loss of life. Based on the Global Earthquake Model (GEM) guidelines, this study assesses empirical tsunami fragility to inventory 2018 Sunda Strait, Sulawesi–Palu, 2004 Indian Ocean (Khao Lak–Phuket, Thailand) tsunamis. Fragility curves represent impact characteristics structural components...
Australia has a low to moderate seismicity by world standards. However, the seismic risk is significant due legacy of older buildings constructed prior national implementation an earthquake building standard in Australia. The 1989 Newcastle and 2010 Kalgoorlie earthquakes are most recent Australian cause damage unreinforced masonry (URM) light timber frame structures have provided best opportunities examine vulnerability these types. This paper describes two above-mentioned types with...
On 30 October 2020, an earthquake of M w 6.9 hit the Aegean coasts Turkey and Greece. The epicentre was some 14 km northeast Avlakia on Samos Island, 25 southwest Seferihisar, Turkey, triggering also a tsunami. event has been followed by >4,000 aftershocks up to 5.2 Earthquake Engineering Field Investigation Team (EEFIT) immediately gathered team conduct hybrid reconnaissance study, bringing together remote field investigation techniques. mission took place between 16 November 17...
Catastrophe models quantify potential losses from disasters, and are used in the insurance, disaster-risk management, engineering industries. Tsunami fragility vulnerability curves key components of catastrophe models, providing probabilistic links between Intensity Measures (TIMs), damage loss. Building due to tsunamis can occur fluid forces or debris impact; two effects which have different implications for building levels failure mechanisms. However, existing functions generally derived...
On 30th October 2020, an earthquake of magnitude 6.9 hit the Aegean coasts Turkey and Greece. The epicentre was some 14 km northeast Avlakia settlement on Samos Island, 25 southwest Turkish town Seferihisar, Izmir. destruction caused concentrated mainly mid-rise RC buildings in certain districts Izmir city. Among diverse building typologies affected by event are traditional/vernacular hybrid timber-masonry masonry that common to This paper summarises discusses damage levels mechanisms...
The degree to which a forecast changes from one issue time the next is an interesting aspect of system. Weather forecasters report that they are reluctant change if judge there risk it being changed back again. They believe such instability detracts message delivered and use automated guidance perceive as having lack stability. A Flip‐Flop Index was developed quantify this characteristic revisions fixed‐event forecasts. index retains physically meaningful units, has simple definition does...
In June 2000, two Mw6.5 earthquakes occurred within a 4-day interval in the largest agricultural region of Iceland causing substantial damage and no loss life. The distance between earthquake epicentres fault rupture was approximately 15 km. Nearly 5000 low-rise residential buildings were affected, some which located faults exposed to strong ground motion from both events. post-earthquakes repair costs for every building epicentral assessed insurance purposes. database is detailed complete...
