What is the quickest method for an individual to attract rescuers' attention if partially buried?

Using a flashlight to signal is the quickest method for an individual to attract rescuers' attention if they are partially buried. This is because a flashlight can produce a bright, noticeable beam of light that can be seen from a distance, even in challenging visibility conditions like low light or darkness.

Flashing the light can create a distinct visual signal that is easier for search and rescue teams to identify while scanning an area, compared to other methods. Vocal noise may not carry far in a chaotic environment, especially if the individual is unable to shout loudly or is too weak to make significant noise. Similarly, signaling with gadgets like a phone may depend heavily on having battery life, signal strength, and the awareness of the rescuers to check for any alerts, which may not be immediate.

In contrast, a flashlight provides a reliable, immediate means of communicating presence, especially in scenarios where visual cues can lead rescuers directly to the individual in need.
