Understanding High-Impact Low Probability Events (Disasters)
Disasters generally fall under high-impact low probability (HILP) events. This means even though they’re not particularly common or likely to happen, they can have massive consequences. Other HILP events include pandemics, cyber-attacks, acts of terrorism, and nuclear incidents.
The consequences of urban disasters are generally exacerbated by a lack of resilience-building initiatives in the affected areas, displaying that development is prioritised over genuine security. To properly create urban resilience, it’s vital that communities and governing bodies properly understand the nature of HILP events, along with the correct ways to prepare for them.
The Challenges & Impacts of HILP Disasters
Certain challenges and impacts come with HILP events and disasters, informing the necessity and nature of effective mitigation strategies. It's only by properly interpreting these factors that real resilience can be built.
Challenges of HILP Events
Predictability:Low probability is more than just a title. The lack of history for events of any particular nature in an area makes it harder to expect when one might be coming, making proper scenario planning less likely to have taken place.
Preparedness: When certain events are less likely or easy to predict, it reduces the likelihood of good preparative measures being taken. Everything from resources to coordination tends to be lacking.
Response: As HILP events seem to come out of nowhere, the need for rapid, decisive, and ultimately effective action is significant. Community members and government officials need to act fast and with authority, even in the face of uncertainty.
Impacts of HILP Events
Loss of Life: HILP Disasters can often lead to massive death tolls, such as the Turkey & Syria Earthquake that took approximately 55,000 lives. These deaths can happen directly or as a secondary consequence due to lack of essential services/infrastructure.
Property & Economic Damage: In serious disasters, huge damage can be done to buildings and structures, massively impacting infrastructure, people’s homes, and the economy. Trade, services, and industry can all take huge hits.
Environmental Damage: The impact on animalsand nature can be huge after disasters, with disruption to natural habitats, ecosystems, and general biodiversity.
Social Disorder:Beyond the death and damage caused by HILP disasters, the impact on social order can be immense. After disasters, crime rates, panic, and general disarray are commonplace.
Only by ascertaining the challenges and impacts of HILP events and disasters can communities effectively implement resilience-building measures.
Factors Contributing to HILP Disasters
It’s also vital to understand that the impacts of HILP disasters aren’t things that appear totally out of the blue, with there being a range of factors that increase the likelihood of extreme weather or seismic activity causing monumental damage.
Geographic Vulnerability: The location of an area will increase the likelihood of disasters taking place. If a city sits closer to the San Andreas Fault Line, it’s more likely to experience seismic events, with coastal areas more likely to experience storms or tsunamis.
Climate Change & Environmental Degradation:Global warming has increased the likelihood of hurricanes, floods, and wildfires. In the same vein, eco degradation, like deforestation, reduces the natural buffers that can increase resilience.
Urbanisation: The pursuit of rapid urban growth can often lead to the construction of shoddy buildings, inadequate infrastructure, and densely populated areas – all of which are factors that increase the impacts of HILP events.
By addressing these natural and manmade factors, it’s easier to develop effective urban resilience strategies.
Proper Risk Management for HILP Events
Having the right plan in place is vital in case of HILP events and disasters taking place. Without a strong system of preparation, response, and recovery in place, communities can be decimated for long periods to come.
Scenario Planning:Communities and governments across the world must have contingency plans in place, along with sufficient disaster preparedness training, regardless of the likelihood of the events.
Resilience Building: Communities and constructive teams must take steps to strengthen infrastructure, institutions, and general structures, ensuring that areas can withstand the impacts more effectively.
Early Warning Systems: Several monitoring and detection systems can be used, including those that leverage space technology, to help with identifying threats and planning timely response approaches.
Collaboration:From individual community members to international government agencies and everyone in between, collaboration is needed in response to HILP events. With private sector entities and humanitarian groups working together, solutions will be found faster.
Proper Land Use:It’s important to use land responsibly, with zoning regulations, building codes, and overarching policies in place to ensure that risks are minimised. For example, there’s the sensible choice of steering development away from hazard-prone areas.
By implementing strategies and techniques, communities can be set up for HILP events and disasters, ensuring that they aren’t left destitute and far from recovery.
Introducing Dr. Albrecht A. Beck
This year at Disasters Expo Europe, we have the pleasure of having Dr. Albrecht A. Beckgive a Keynote Speech on the topic of this newsletter, sharing insights into it far beyond what we can offer.
Dr. Beck’s Career
Albrecht Beck is the Director of Prepared International(PPI), with particular expertise in disaster governance systems and mass evacuation strategy.
Before finding his place as leader of this organisation, he worked for a range of United Nations Organizations related specifically to disaster management, remaining as a member of their London Journal and the World Humanitarian Forum. He even received the Averted Disaster Award in 2023, showing there are few candidates more qualified to offer insights into HILP events and disasters in general.
For access to Dr. Beck’s Seminar – High-Impact Low Probability (HILP) Events In Urban Areas, along with a range of other seminars, an exhibition hall with hundreds of showcasing businesses, and countless networking opportunities, register for your complimentary tickets to Disasters Expo Europe today!
