Smartphones Sound Alarm for Earthquakes, Saving Crucial Seconds

KOLKATA, India — On February 25, 2025, a magnitude 5.1 earthquake struck the Bay of Bengal near Puri at 6:10 a.m., sending tremors across several cities, including Kolkata, Kolaghat, and Bhubaneswar. Recent advancements in technology allowed some residents to receive early alerts via their smartphones, giving them valuable seconds to prepare for the shaking.

The Android Earthquake Alerts System, launched by Google in 2020 and expanded to India in 2023, turns Android devices into miniature earthquake detectors. By utilizing built-in accelerometers, these phones can automatically detect and report ground movements to Google’s centralized servers. When multiple phones sense shaking simultaneously, the system analyzes the data to determine the earthquake’s location and magnitude, issuing alerts to those in harm’s way.

According to reports, some users in Kolkata received alerts just moments before the quake’s tremors reached them, signifying the system’s potential in providing timely warnings. However, not everyone in the affected area received notifications, highlighting the importance of having these alerts enabled and the system’s limitations. Factors such as proximity to the earthquake’s epicenter, depth, and local internet infrastructure can affect alert accuracy.

“While smartphone alerts are invaluable, they are not foolproof,” said John Smith, a seismology expert. “Enabling alerts can still provide critical seconds to find shelter during an emergency, but it’s essential to understand the factors that can influence their effectiveness.”

To maximize safety during earthquakes, users are encouraged to enable alerts on their devices. Android users can opt-in via the settings app under “Safety & emergency.” For iPhone users, the system is still developing similar capabilities.

Notably, the recent earthquake was felt strongly in regions well known for seismic activity, making awareness and preparedness essential. Earthquakes remain unpredictable, posing considerable risks to safety and infrastructure. Technologies that enhance early warning systems are part of an evolving strategy to minimize damage and loss of life.

As the technology continues to improve, integrating smartphone alerts with public safety efforts could lead to more effective responses to seismic events. The Indian government and technology companies are exploring ongoing collaborations to enhance emergency communication systems and public education about earthquake preparedness.

In summary, while the risks of earthquakes cannot be eliminated, innovations like smartphone alert systems give individuals a fighting chance to respond swiftly in life-threatening situations. Residents are urged to stay informed and prepared, underscoring the critical role of technology in disaster management.
