Inability to quickly verify earthquake safety and locate missing family members during natural disasters

When earthquakes strike, people in affected areas and their relatives abroad face critical delays in confirming whether loved ones are safe, accessing emergency resources, and coordinating rescue efforts. Current communication infrastructure often collapses during disasters, leaving families in agonizing uncertainty for hours or days. Existing solutions like traditional phone lines and social media are unreliable when infrastructure fails, forcing people to pay for expensive international calls or wait for official aid organizations to provide updates.
