Overall, data analytics can provide emergency managers with valuable insights that can help them to respond more effectively to crises, and to make better decisions that can save lives and minimize damage.
In addition to the uses I mentioned earlier, data analytics can be used in other ways in emergency management such as:
- Risk assessment: Identifying potential hazards, such as natural disasters, technological hazards, and terrorist attacks, and assessing the likelihood of their occurrence and the potential consequences. This can help emergency managers to prioritize resources and develop response plans.
- Public health surveillance: Collecting and analyzing data on the spread of infectious diseases, such as tracking the spread of COVID-19. This can help emergency managers to identify outbreaks and take steps to control the spread of disease.
- Social media analysis: Monitoring social media platforms for information about an emergency, such as tracking the spread of rumors or misinformation, or identifying the location of people in need of assistance.
- Logistics: Optimizing logistics operations, such as transportation and supply chain management, during a crisis. This can help emergency managers to ensure that essential supplies, such as food and medicine, reach people in need in a timely manner.
- Business continuity: Identifying and analyzing the potential impact of a crisis on businesses and the economy, and developing plans to minimize disruption.
Data analytics can also be used to integrate the data from multiple sources, and to create a more efficient and accurate common operational picture. It is an important tool to help emergency managers to make informed decisions in real-time, and to be able to take appropriate actions to manage the crisis.
What is Big Data
Big data refers to extremely large and complex data sets that are too difficult to process and analyze using traditional data management and analysis tools. The term “big” refers not only to the volume of data but also to the velocity and variety of data that is being generated.
The volume of big data is typically measured in terabytes, petabytes, and even exabytes, and is growing exponentially due to the increasing use of digital technologies and the internet of things. Big data is characterized by its high velocity, meaning that it is generated and updated rapidly in real-time. In addition, big data is often unstructured, meaning that it does not fit neatly into traditional rows and columns like structured data in databases.
Big data has the potential to provide valuable insights into a variety of areas, including business operations, scientific research, and public policy. However, traditional data management and analysis tools are often not sufficient to handle the complexity and scale of big data. As a result, new technologies and techniques have been developed, including distributed computing frameworks like Apache Hadoop and Spark, machine learning algorithms, and data visualization tools, to help manage and analyze big data.
4 Ways Big Data is Revolutionizing Emergency Management
Analyzing and observing Big Data patterns is not only a beneficial practice within businesses, it can also improve the efficiency and effectiveness of emergency and disaster management organizations. Thanks to the availability and usage of smartphones and social media, disasters can be measured with real-time information and met with a rapid, accurate and precise response. Big Data has the ability to enhance disaster recovery by utilizing community information and connecting victims with emergency responders and family.
Emergency personnel can minimize their search time and maximize their recovery time when they have access to real-time information emphasizing the areas most affected. Working along with professional insight and satellite imagery, Big Data has started trends that have already saved lives and proven effective within the emergency management field.
Crisis Mapping
Ushahidi, a non-profit company that creates open-source software for gathering information, developed and utilized an interactive mapping platform in 2008 that plotted violent areas following the Kenyan presidential election. They gathered information from eyewitness sources via online platforms, and plotted them on a Google map to help those in danger navigate their way to safety.
Ushahidi was experimenting with crisis mapping: the real-time creation and display of reports submitted through email, text message and social media on interactive geographical maps. They implemented it again during the 2010 earthquake in Haiti, and it resulted in many victims being rescued by first responders. The U.S. Marine Corps, who was first on the scene, felt that the crisis mapping assisted them in quickly locating and recovering victims.
In order for crisis mapping to be effective, those in disaster zones have to partake in Big Data collection by providing as much reliable information as they can so that organizations like Ushahidi can make it publicly available. Disasters can separate people from their families, and trends like crisis mapping just may help emergency responders find them.
Connecting Missing People with Their Families
Companies like Google and Facebook are also interested in helping communities during emergency situations, particularly in reducing recovery time. They have implemented online systems specific to connecting people with their loved ones during and after disasters in real-time.
Immediately following the 2010 earthquake in Haiti, Google released its “Person Finder” feature. This allows for an immediate way to reconnect post-disaster. In short, anyone can enter information related to missing people in an attempt to connect themselves or others with those they are looking for. Within the first two days after the earthquake, Person Finder was updated 5,300 times as people searched for friends and family caught in the affected area.
Another example is Facebook’s “Safety Check Service”. It’s an active service that reaches out to people who are near disaster areas to discover if they are safe and to ask for more real-time information regarding the situation. These services employ Big Data as a recovery tool..
Social Media Mining
Emergency management organizations like FEMA and Red Cross have noticed Big Data can help fill in gaps of information that may be crucial to a rapid response. When disasters like a flood hit communities hard enough to cause an evacuation, it’s important to know what roads are open, where gas is available and if anyone is trapped.
Although satellite imagery is effective, it isn’t always available and may not show the whole picture. Eyewitness level pictures and posts via social media from the affected area, however, can be extremely effective in showing potential hazardous locations. Utilizing satellite and social media information in tandem provides responders with a clearer picture of the situation that may not be as easily seen from one point of view.
Event Simulations
Emergency management organizations also practice for when actual disasters occur. Unfortunately they have suffered in the past from a lack of realistic statistics that feed the simulations. With big data, safety professionals can better prepare these disaster simulations for more accurate implementations.
Large batches of data improve emergency preparedness by analyzing previous disasters’ statistics. They assist organizations in visualizing what worked and didn’t work with more precise data. Until recently, emergency action plans often had to wait until an actual disaster occurred to test their effectiveness because the simulations didn’t accurately represent the possible results. Now big data is helping organizations understand exactly what they are up against before it happens.
Big Data and Emergency Management Go Together
Whether it is through crisis mapping or event simulation, Big Data is pioneering new methods of emergency management. It uses the analysis of information gathered from the community in real-time to assist those in need and those looking for loved ones lost in disasters. Big Data and emergency management’s newfound progressive relationship opens up new career opportunities for those who want to find innovative ways to help others.
Conclusion
Data Analytics can play a crucial role in emergency management, helping to identify and respond to crises more effectively. By leveraging data from various sources, including social media, weather sensors, and emergency response systems, emergency management teams can gain valuable insights into the situation on the ground, anticipate potential risks, and allocate resources more efficiently.
Data analytics can also help to identify trends and patterns over time, allowing emergency management teams to make informed decisions and develop more effective response strategies. However, to fully realize the potential of data analytics in emergency management, it is essential to have the right infrastructure, tools, and expertise in place. By investing in data analytics capabilities and building partnerships with relevant stakeholders, emergency management organizations can improve their response to emergencies and better protect communities.
