Final answer:
The priority after a disaster is to rescue victims, provide first aid, and ensure their safety. Crowdsourcing helps prioritize urgent needs for effective disaster response.
Step-by-step explanation:
Immediately after a disaster, the response stage begins, and the priority activity in the immediate aftermath of a disaster is to rescue victims from dangerous situations, administer first aid, and ensure their safety. This can include searching and rescuing victims from burning buildings, accident sites, water hazards, and other precarious scenarios. The actions taken by first responders like firefighters are critical; they must quickly dress in fire-resistant clothing and breathing apparatus, assess the situation, and use two-way radios to communicate with superiors and receive further instructions. As part of a concerted disaster relief effort, the use of crowdsourcing has proven effective in organizing data from social media and other communication channels to prioritize the most urgent needs for rescue and medical assistance, as demonstrated during disasters like the 2010 Haiti earthquake and the 2011 Japanese earthquake and tsunami.
