Earthquake just now? QuakeAlert monitors earthquakes worldwide in real time and alerts you when it matters: push notifications for quakes in your country, an interactive 3D globe, satellite map and news with official sources. LIVE 3D GLOBE Every earthquake from the last hours on an interactive 3D globe — magnitude, depth and location, with tectonic plates and a live pulse. ALERTS FOR YOUR COUNTRY Get notified when an earthquake strikes your country. You choose the minimum magnitude (M3+, M4.5+ or M6+). Major quakes worldwide reach everyone. SATELLITE MAP Explore every event on satellite imagery with tectonic plate boundaries, period and magnitude filters, and search by region. NEWS WITH SOURCES Reports on the most significant earthquakes, built on USGS data and verified sources — official agencies and international press, always with links. Articles are automatically generated and rigorously validated; they never replace guidance from authorities. TSUNAMI WARNINGS Official NOAA warnings for your country's coast. You can switch them off anytime. INSIDE THE EARTH Explore a 3D cutaway of the planet and see where earthquakes are born. SAFETY GUIDE What to do before, during and after an earthquake, and how to recognize tsunami warning signs. TECHNICAL DETAIL Full history with PAGER, intensity maps (ShakeMap), felt reports, aftershock risk and a tectonic summary in your language. OFFICIAL DATA USGS (United States Geological Survey), EMSC (European-Mediterranean Seismological Centre) and Brazil's seismographic network (USP/RSBR). IMPORTANT QuakeAlert notifies you about earthquakes ALREADY DETECTED by official seismic networks. It is not an early-warning system and does not predict earthquakes. In an emergency, always follow local civil defence. Available in English, Spanish and Portuguese.

Verdict
The clearest difference is ads: Geo Alarms at none against QuakeAlert's shown. Geo Alarms also leads on device support (3 vs 1). QuakeAlert's advantage is update cadence (every 2 days vs fortnightly). On price, in-app purchases and iOS requirement there is nothing between them.
