Design a modern, minimalistic logo for a mobile app named "AlertGo", a real-time campus emergency alert system. The logo should feature a shield combined with a location pin icon, symbolizing safety and real-time tracking. Include subtle elements like a pulse signal or alert wave to represent emergency response. Use a clean and futuristic style with a red, white, and dark blue color palette. The typography should be bold, sans-serif, and tech-inspired. Flat design, vector style, high resolution, suitable for app icon and branding.
