A disaster is an event that causes serious harm to people, buildings, economies, or the environment, and the affected community cannot handle it alone. Natural disasters like avalanches, floods, earthquakes, and wildfires are caused by natural hazards. Human-made disasters like oil spills, terrorist attacks and power outages are caused by people. Nowadays, it is hard to separate natural and human-made disasters because human actions can make natural disasters worse. Climate change also affects how often disasters due to extreme weather hazards happen.
Landslides, also known as landslips, or rockslides, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides.
A natural disaster is the very harmful impact on a society or community after a natural hazard event. Some examples of natural hazard events include avalanches, droughts, earthquakes, floods, heat waves, landslides, tropical cyclones, volcanic activity and wildfires. Additional natural hazards include blizzards, dust storms, firestorms, hails, ice storms, sinkholes, thunderstorms, tornadoes and tsunamis. A natural disaster can cause loss of life or damage property. It typically causes economic damage. How bad the damage is depends on how well people are prepared for disasters and how strong the buildings, roads, and other structures are. Scholars have been saying that the term natural disaster is unsuitable and should be abandoned. Instead, the simpler term disaster could be used. At the same time the type of hazard would be specified. A disaster happens when a natural or human-made hazard impacts a vulnerable community. It results from the combination of the hazard and the exposure of a vulnerable society.
Induced seismicity is typically earthquakes and tremors that are caused by human activity that alters the stresses and strains on Earth's crust. Most induced seismicity is of a low magnitude. A few sites regularly have larger quakes, such as The Geysers geothermal plant in California which averaged two M4 events and 15 M3 events every year from 2004 to 2009. The Human-Induced Earthquake Database (HiQuake) documents all reported cases of induced seismicity proposed on scientific grounds and is the most complete compilation of its kind.
Emergency management is a science and a system charged with creating the framework within which communities reduce vulnerability to hazards and cope with disasters. Emergency management, despite its name, does not actually focus on the management of emergencies; emergency management or disaster management can be understood as minor events with limited impacts and are managed through the day-to-day functions of a community. Instead, emergency management focuses on the management of disasters, which are events that produce more impacts than a community can handle on its own. The management of disasters tends to require some combination of activity from individuals and households, organizations, local, and/or higher levels of government. Although many different terminologies exist globally, the activities of emergency management can be generally categorized into preparedness, response, mitigation, and recovery, although other terms such as disaster risk reduction and prevention are also common. The outcome of emergency management is to prevent disasters and where this is not possible, to reduce their harmful impacts.
Brian E. Tucker is an American seismologist specializing in disaster prevention. He is also the founder of GeoHazards International (GHI), a non-profit dedicated to ending preventable death and suffering caused by natural disasters in the world’s most vulnerable communities.
Tropical cyclone engineering, or hurricane engineering, is a specialist sub-discipline of civil engineering that encompasses planning, analysis, design, response, and recovery of civil engineering systems and infrastructure for hurricane hazards. Hurricane engineering is a relatively new and emerging discipline within the field of civil engineering. It is an integration of many recognized branches of engineering, such as structural engineering, wind engineering, coastal engineering, and forensic engineering, with other recognized sciences and planning functions such as, climatology, oceanography, architecture, emergency management and preparedness, hazard mitigation, and hazard vulnerability analysis. Hurricane engineering aims to minimize risks to human safety, the natural and built environment, and business processes.
Disaster risk reduction aims to make disasters less likely to happen. The approach, also called DRR or disaster risk management, also aims to make disasters less damaging when they do occur. DRR aims to make communities stronger and better prepared to handle disasters. In technical terms, it aims to make them more resilient or less vulnerable. When DRR is successful, it makes communities less the vulnerable because it mitigates the effects of disasters. This means DRR can make risky events fewer and less severe. Climate change can increase climate hazards. So development efforts often consider DRR and climate change adaptation together.
A hazard is a potential source of harm. Substances, events, or circumstances can constitute hazards when their nature would potentially allow them to cause damage to health, life, property, or any other interest of value. The probability of that harm being realized in a specific incident, combined with the magnitude of potential harm, make up its risk. This term is often used synonymously in colloquial speech.

O’Rourke took his Bachelor of Science in civil engineering at Cornell's engineering college in 1970 and his doctorate at the University of Illinois Urbana-Champaign in 1975.
Coastal flooding occurs when dry and low-lying land is submerged (flooded) by seawater. The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding. The seawater can flood the land via several different paths: direct flooding, overtopping or breaching of a barrier. Coastal flooding is largely a natural event. Due to the effects of climate change and an increase in the population living in coastal areas, the damage caused by coastal flood events has intensified and more people are being affected.
In emergency management, higher learning institutions must frequently adapt broad, varied policies to deal with the unique scope of disasters that can occur in on-campus settings. Hurricanes, earthquakes, tornadoes, and wildfires are among some of the most common natural disasters that possess the capacity for large losses of life and property, with the potential to effectively destroy a university community. Man-made crises also can pose a serious threat to life and property, as was evident in the case of the 2007 Virginia Tech shooting. In order to preemptively reduce or prevent the severity of emergency situations, universities must coordinate and implement policies to effectively eliminate unnecessary risks' and decrease potential losses.
The National Society for Earthquake Technology – Nepal (NSET) is a Nepali non-governmental organization working on reducing earthquake risk and increasing earthquake preparedness in Nepal as well as other earthquake-prone countries.
Disaster preparedness in museums, galleries, libraries, archives and private collections, involves any actions taken to plan for, prevent, respond or recover from natural disasters and other events that can cause damage or loss to cultural property. 'Disasters' in this context may include large-scale natural events such as earthquakes, flooding or bushfire, as well as human-caused events such as theft and vandalism. Increasingly, anthropogenic climate change is a factor in cultural heritage disaster planning, due to rising sea levels, changes in rainfall patterns, warming average temperatures, and more frequent extreme weather events.
All Hands and Hearts (AHAH) is a U.S. 501(c)(3) nonprofit organization. The organization's current structure formed in late 2017, when two existing nonprofits, All Hands Volunteers and Happy Hearts Fund merged to become All Hands and Hearts. All Hands Volunteers was founded in September 2005 by philanthropist and businessman David Campbell to provide relief to residents in areas affected by natural disasters worldwide. Happy Hearts Fund, founded by philanthropist and supermodel, Petra Němcová, sought a similar goal, to help communities recover after a disaster event. All Hands and Hearts is based in Mattapoisett, Massachusetts.
