Introduction: A Life-Saving Tool in Your Pocket
In an age where disasters can strike without warning, your smartphone might be more powerful than you think—especially when it comes to early earthquake alerts. Google and Samsung have developed alert systems for Android devices that can give you precious seconds to prepare for seismic activity. While Google’s system has been in place since 2020, Samsung is stepping up with its own version, giving users more control and potentially broader coverage. Understanding how to enable these alerts—and what to expect—can make a critical difference in times of danger.

Google has expanded its Android Earthquake Alerts System across all 50 U.S. states and six territories, including places like Puerto Rico and Guam. Originally launched in California, Oregon, and Washington, the system worked in partnership with the USGS and CalOES, utilizing the ShakeAlert network. However, Google’s latest update goes beyond traditional seismic sensors, using your phone’s accelerometer to detect ground motion in real-time.
Once an earthquake of magnitude 4.5 or higher is detected, Google sends out two types of alerts. A “Be Aware” notification indicates mild to moderate shaking, while a “Take Action” alert warns of more intense tremors and advises users to immediately take cover. Both alerts estimate the distance to the epicenter and come with follow-up tips on what to do afterward. If users prefer not to participate, they can disable the alerts or stop their phone from contributing to Google’s seismic network via the settings.
Samsung, not to be outdone, launched its own earthquake alert system in June 2025 as part of the One UI 8 update. While details are limited, the Samsung system is presumed to function similarly to Google’s. However, it offers a unique edge: users can lower the detection threshold to as little as magnitude 1.0 and customize alerts differently for daytime and nighttime. This granular control could make Samsung’s system more adaptable and responsive than Google’s.
To activate these alerts on Android, users should navigate to Settings > Safety & Emergency > Earthquake Alerts and toggle the feature on. A demo option shows how the alert will sound and appear. Though warning times might only be a few seconds, they could be the difference between injury and safety. With both systems offering early alerts, users everywhere—not just those in quake zones—stand to benefit from this potentially life-saving feature.
What Undercode Say:
The introduction of dual earthquake alert systems by Google and Samsung marks a turning point in smartphone safety technology. Google’s approach, which crowdsources accelerometer data from millions of Android devices, reflects the growing power of decentralized, real-time networks. This method fills a critical gap in areas that lack dense seismograph networks and leverages the ubiquity of smartphones as a public safety net.
Samsung’s decision to build its own layer atop Android shows increasing OEM involvement in user safety. What’s especially interesting is the brand’s decision to give users more control. The option to set thresholds as low as 1.0 is not just a tech flex—it’s a response to growing demand for hyper-local and personalized alerts. This flexibility acknowledges that not all users are in the same context—night shift workers, parents, or those in quake-prone areas may all have different sensitivities to alerts.
Yet, there’s also a hidden competitive edge here. Samsung might be creating a loyalty moat through superior built-in features. If users come to trust Samsung’s alerts more than the default Android experience, it’s a win in both customer retention and brand authority. The move also highlights the future of safety tech: customizable, real-time, and device-driven rather than institution-driven.
This development also raises questions about standardization. What happens when two alert systems coexist on the same device? Will they conflict or overlap? Could one override the other? Samsung has yet to clarify if its system complements or overrides Google’s. That said, the availability across S, A, and Z series ensures wide adoption, especially in global markets prone to seismic risks like Japan, Indonesia, or Turkey.
The takeaway is clear: as natural disasters grow more unpredictable, digital infrastructure must become more adaptive and personal. These earthquake alerts aren’t just convenience features—they represent a broader shift where smartphones evolve from communication tools to real-time crisis management systems. The future of disaster response might very well live in your pocket.
🔍 Fact Checker Results
✅ Google’s Earthquake Alert System covers all 50 U.S. states and six U.S. territories
✅ Samsung’s customizable thresholds go as low as magnitude 1.0 with separate day/night settings
❌ Samsung has not officially disclosed the technical workings of its alert system
📊 Prediction: Earthquake Tech Will Drive Future Smartphone Innovation
By 2026, expect at least one major smartphone manufacturer—possibly Apple or Xiaomi—to roll out its own native earthquake alert system. With increasing global attention on disaster readiness and climate resilience, early warning systems will become a standard smartphone feature, similar to emergency SOS. Regulatory bodies may even require standardized alert mechanisms across all smart devices in earthquake-prone regions. The smartphone will not just be a tech device—it’ll be an essential tool for survival.
