Crowd sourcing disaster information through social media is called as:
Crisis Mapping: Crowd-Sourcing Disaster Information
The process of gathering and analyzing disaster-related information collected from the public, especially via social media platforms, is known as crowd-sourcing. This practice is specifically referred to when applied during or after a disaster event.
Understanding Crisis Mapping
Crisis mapping is the term used to describe the practice of using crowdsourced information, often gathered rapidly from social media and other digital sources during a crisis or disaster. This data is then processed and visualized, typically on maps, to provide situational awareness for responders and decision-makers.
- It leverages the power of the crowd to collect real-time information about a disaster's impact.
- Key aspects include verification, analysis, and dissemination of the crowd-sourced data.
- The goal is to improve the speed and effectiveness of emergency response efforts.
Evaluating Other Options
The other options represent related but distinct concepts:
- Risk mapping focuses on identifying areas prone to potential hazards before an event occurs.
- Mitigation mapping involves identifying strategies and areas for reducing the potential impact of hazards.
- Prevention mapping aims to identify measures or areas critical for preventing disasters from happening or escalating.
None of these specifically encompass the real-time, crowd-sourced data collection from social media during a disaster event, unlike crisis mapping.
