Read the original article here In the past year, the world has witnessed many severe disasters caused by multiple hazards whose impacts overlapped in time and space. February this year, two severe earthquakes hit Syria and Turkey shortly after each other, followed by two more powerful earthquakes and over a hundred aftershocks in subsequent weeks [1,2]. The disaster caused over 48 thousand fatalities, and many people are still missing [3]. Another example is Afghanistan in June 2022, where an earthquake struck when people were already affected by a multi-year drought, followed by extreme rainfall and flooding in August [4,5]. Pakistan too was faced with an unfortunate series of events over the course of 2022. After a period of drought, heatwave-induced glacier melting combined with a heavy rain season resulted in devastating flooding, landslides, and disease outbreaks [4,6]. Additionally, the country was dealing with severe wildfires in May and June 2022 [7]. The United Nations Office for Disaster Risk Reduction defines such complex events as multi-hazard events involving the simultaneous or sequential occurrence of two or more hazards and their potentially interrelated effects [8]. For example, the flash floods in Pakistan were likely exacerbated by the wildfires in other regions [7]. Due to connections and feedback between multiple events, the combined impact of a multi-hazard event can be different from the sum of the impacts of multiple individual disasters [9]. Despite growing awareness among disaster risk researchers and managers of the importance of adopting a multi-hazard approach [10,11], complex multi-hazard events are often not recognised and reported upon as such by the mainstream media and disaster reporting websites. Such a fragmented approach to disaster reporting can result in an incomplete understanding of disasters and their impacts. It can limit the general public awareness of multi-hazard disasters, which in turn can affect disaster risk reduction and resilience-building efforts. For example, regarding the Afghanistan hazards, ReliefWeb – a humanitarian information service provided by the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) – reports the drought, earthquake, and flood as three separate disasters (Fig 1). The coincidence of these hazards is only briefly, and in some cases not at all, mentioned in the descriptions of the individual disasters [12-14].   Fig 1. A snapshot of the disasters as reported by ReliefWeb on their website for Afghanistan mid- and end-2022 [15].   In some instances, disasters are reported together (Fig 2), but this mainly occurs in the case of physically dependent disasters (i.e. where the occurrence of one hazard triggers that of another), while a multi-hazard event can also consist of multiple independent hazards with overlapping impacts [9].   Fig 2. A snapshot of the disasters as reported by ReliefWeb on their website for Afghanistan early 2012 [15].   This single-hazard-oriented reporting that can be observed in the provision of information by ReliefWeb and other humanitarian information services is also reflected in the way that disaster data is reported by aid organizations such as the International Federation of Red Cross and Red Crescent Societies (IFRC), but also more scientific sources, such as the Emergency Events Database EMDAT or the UNDRR’s Desinventar databases. The data that can be retrieved from these sources provide information per event, looking at one hazard at a time [16-18]. EMDAT provides a column for ‘associated disasters’, but this accounts, again, only for associations between physically dependent hazards. For example, the two tropical cyclones that hit northern Mozambique in 2019 only six weeks apart; these are not associated with each other in the EMDAT database, while the impacts of the second cyclone compounded with the residual impacts of the first [19]. The sequential disease outbreak resulting from the sanitation infrastructure disruptions [20] is also not linked to the storms as an associated disaster. While it is understandable that attributing impacts to individual natural hazards can be relevant for research purposes, it can be questioned if attributing impacts or emergency funding to single hazards is even possible when disaster impacts are strongly intertwined. Also, inconsistent and single-hazard-oriented reporting can often be observed when it comes to multi-hazard events in the mainstream media. When reporting on the first two severe earthquakes that struck Syria and Turkey in early February this year, the Guardian, for example, inconsistently uses ‘earthquake’ and ‘earthquakes’ in their articles: Two weeks after the Turkey-Syria Earthquakes – a photo essay Guardian article by Lorenzo Tondo and Ruth Michaelson, published February 21, 2023 Thousands dead, millions displaced: the earthquake fallout in Turkey and Syria Guardian article by Oliver Holmes, Elena Morresi and Finbarr Sheehy, published February 21, 2023     Another example is an article in the New York Times regarding the floods and looming food crisis faced by Pakistan in 2022:  ‘Very Dire’: Devastated by Floods, Pakistan Faces Looming Food Crisis New York Times article by Christina Goldbaum and Zia ur-Rehman, published September 11, 2022   While the article explains how the floods affected the country’s agricultural sector, for example, through the destruction of crops, this provides a simplified view of the actual situation. The food security conditions in the region, while worsened by the flood impacts, were already dire prior to the floods due to the drought and heat wave in early 2022, combined with economic instability and political unrest [21]. Research has shown that both consecutive hazard conditions and unstable socio-economic conditions can significantly affect the impacts of such a multi-hazard disaster [22]. However, recent news articles have taken initial steps towards a more comprehensive multi-hazard approach to disaster reporting. There are examples of articles discussing multiple hazards and their interconnections, like this article by the Guardian: Bushfires, ash rain, dust storms and flash floods: two weeks in apocalyptic Australia Guardian article by Kate Lyons, published January 24, 2020 This comprehensive article explains the natural hazards experienced by Australia in 2019-2020 (i.e. bushfires, extreme rain, flash floods, heatwave, mud streams, drought, dust and hail storms) and how they were interconnected. Recently the BBC even used the term ‘multi-hazard’ in their reporting [23]. This is a positive trend that should be continued into the future. The widespread panic and confusion currently observed in Syria and Turkey after

Read the original article here COVID-19 has been a disruptive ‘tsunami’ that most countries were not prepared to handle. The pandemic has been representing a global slow-onset long-lasting disaster that has drastically challenged all emergency management systems worldwide. The pandemic slow-onset disaster has been characterized by a prolonged emergency phase with varying intensity levels, and a cyclic behavior, where the interpandemic, alert, pandemic, and transition phases [1] alternated for more than two years. In the first phases of the pandemic spread, the level of preparedness – including pre-existing protocols, development of testing and tracing capabilities, and the stockpile of personal protective equipment– was not adequate to deal with such an unexpected and complex event. Moreover, the health systems have been stretched to their limits, with a dramatic overload in intensive care units. Capano [2] identified that almost all Western countries had to go through a problem-recognition process before reacting effectively to the pandemic outbreak. After the first phase of denial (‘it is not happening’), then the countries went through the phases of normalization of the risk (‘it will not happen here’), underreaction (‘we must do something to show that we are doing something’), and finally arrived at the recognition and reframing (‘it is here, and it is our problem!’).   Is COVID-19 a black swan?  The scientific community and public opinion have widely debated whether the COVID-19 pandemic could be considered a Black Swan event, i.e., an event with an outsized impact, that is harder to predict and even harder to compute its probabilities. Professor John Drake, Director of the Center for the Ecology of Infectious Diseases at the University of Georgia (US), says it’s not [3]. Drake says that pandemics have always been part of human history and the number of recorded epidemics is vast. “Epidemics that affect a lot of people are less common, but certainly not rare” [3]. On the other hand, the COVID-19 pandemic has been different from any other disaster type and even other diseases [4]. Indeed, the COVID-19 pandemic management has involved temporal and spatial scales very different from those characterizing sudden-onset natural hazards such as earthquakes, floods, or landslides [5]. Regarding the temporal scale, the COVID-19 pandemic disaster has been ongoing for more than two years, with the number of cases and deaths continuously varying with time. As a consequence, there has not been a clear distinction between the impact and response phases and casualties can continue to increase even when response activities are already implemented [4]. Looking at the spatial scale, COVID-19 has almost simultaneously struck wide areas – even larger than a continent – contrary to all other disaster types that are geographically circumscribed. Several surrounding countries were coping at the same time with a high demand for emergency response resources, hampering the allocation of resources from one place to another, and leading to a reduction in international assistance [4,5].   A complex multi-risk scenario To make the scenario even more complex, the COVID-19 pandemic has overlapped and interacted with co-occurring disasters that happened all over the world since the beginning of the pandemic crisis [5,6,7,8], such as the earthquake in Croatia, the tropical cyclone Harold, and the floods in Western Europe. The lack of multi-hazard risk Early Warning Systems has increased the risk of compounding impacts originating from natural hazard events during the COVID-19 pandemic, including both the natural hazard disaster’s effects being worse than they would otherwise be without COVID-19 and an additional spread of COVID-19 due to the presence of a compound disaster [6]. A series of complex logistics and ‘‘asynergies” arose in this multi-hazard management since procedures and protocols for the integrated management of pandemics and natural hazards were underdeveloped or absent [9]. Indeed, emergency response for natural hazard disasters, such as an earthquake can necessitate evacuation and mass gathering measures, which are in contrast with the pandemic prevention strategies, such as physical distancing and home isolation. For example, staying at a shelter during the COVID-19 pandemic would potentially lead to a pandemic outbreak, highlighting what has been defined by Sayfouri et al. [10] as the “Contradictory Nature” of COVID-19 and the Earthquake Co-occurrence. The co-occurrence of COVID-19 and other natural hazards has dramatically highlighted the need for an improved scientific understanding of the interactions between natural hazards and pandemics, and for a better assessment of these complex multi-risk scenarios, where both synergies and trade-offs among disaster risk reduction measures can arise.   COVID-19 and natural hazards at EGU23  During the next EGU General Assembly, which will be held in Vienna from 23 to 28 April 2023, the Union Symposium US1 ”Managing compounding impacts from extreme events through societal crises”, will address how Europe can more effectively face multiple hazards and compounding impacts from extreme events through ongoing societal crises, such as the COVID-19 pandemic crisis. Moreover, complex multi-hazard risk scenarios and the interplay between natural hazards and pandemics will be explored in several scientific sessions inside the program of the Natural Hazards Division, such as NH9.2 New data and methods to explore the interplay between natural hazards and social vulnerability, NH9.3 Resilience to natural hazards: assessments, frameworks and tools, and NH10.1 Innovative approaches for multi-hazard risk assessments and their applications to disaster risk reduction and climate change adaptation, among others.
