Official Data Sources Used by Tsunami Shield: Where Our Alerts Come From
One of the most common questions people ask is: where do your alerts come from? Tsunami Shield monitors information published by official monitoring agencies and recognised scientific organisations around the world.
When it comes to natural hazards, reliable information matters. One of the most common questions people ask is: "Where do your alerts come from?"
Tsunami Shield is designed to help users stay informed by monitoring information published by official monitoring agencies and recognised scientific organisations. Our goal is simple: deliver timely information that helps support awareness and preparedness during coastal emergencies.
Why Official Data Sources Matter
Tsunamis are complex natural events. Understanding whether a tsunami exists, which areas may be affected, and what actions people should take requires sophisticated monitoring systems.
Modern warning centres use earthquake monitoring networks, deep-ocean sensors, sea-level gauges, satellite communications, and advanced computer modelling. The information produced by these systems forms the foundation of tsunami warnings around the world.
Pacific Tsunami Warning Center (PTWC)
The Pacific Tsunami Warning Center is one of the world's leading tsunami monitoring organisations. Located in Hawaii, the centre monitors earthquakes, tsunami activity, sea-level observations, and Pacific-wide hazards.
The centre provides tsunami information for many Pacific regions and works closely with emergency management organisations throughout the world.
National Tsunami Warning Center (NTWC)
The National Tsunami Warning Center is part of the United States tsunami monitoring system. The centre monitors earthquakes, tsunami threats, coastal observations, and warning information.
The NTWC provides tsunami information for portions of North America and surrounding regions.
United States Geological Survey (USGS)
The United States Geological Survey operates one of the world's largest earthquake monitoring systems. USGS provides earthquake detection, magnitude information, epicentre locations, and seismic monitoring information.
Rapid earthquake information plays an important role in tsunami assessment and monitoring.
GeoNet New Zealand
GeoNet operates New Zealand's geological hazard monitoring system. GeoNet monitors earthquakes, volcanic activity, tsunami information, and geological hazards.
New Zealand's location along the Pacific Ring of Fire makes geological monitoring especially important.
Australian Monitoring Agencies
Australia maintains monitoring and emergency management capabilities that contribute to tsunami awareness and public information. These systems support earthquake monitoring, tsunami assessments, coastal hazard information, and emergency communications.
Global Disaster Alert and Coordination System (GDACS)
GDACS is an international platform that provides disaster monitoring information for major events around the world. The system provides information on earthquakes, tsunamis, tropical cyclones, floods, and other major disasters.
GDACS helps support situational awareness during significant international events.
Why Multiple Sources Matter
No single organisation monitors every hazard around the world. Modern tsunami preparedness relies on multiple monitoring systems, international scientific cooperation, regional expertise, and cross-verification of information.
Using information from multiple recognised sources helps improve resilience and awareness.
What Tsunami Shield Does
Tsunami Shield monitors information from recognised scientific and warning organisations and delivers information to users in an easy-to-understand mobile experience.
Features include official tsunami alerts, earthquake monitoring, saved locations, regional monitoring, preparedness resources, and emergency information tools. The app is designed to help users remain informed and prepared when coastal hazards occur.
Powered by Official Sources
Tsunami Shield monitors information from the world's leading scientific and warning organisations — including PTWC, NTWC, USGS, GeoNet, and GDACS — to deliver reliable alerts and earthquake monitoring to your phone.
Does Tsunami Shield Predict Tsunamis?
No. Tsunami Shield does not predict earthquakes or tsunamis. Earthquake prediction is not currently possible.
Instead, Tsunami Shield monitors information published by official monitoring organisations and helps deliver relevant information to users in a timely and accessible way.
About Tsunami Prediction
No technology can predict when or where an earthquake will occur. Tsunami Shield monitors official warning information and delivers it to you as quickly as possible — but preparedness and evacuation planning remain essential.
Why Transparency Matters
Transparency is important in emergency information. Users deserve to understand where information originates, who produces warnings, how monitoring systems work, and the limitations of natural hazard forecasting.
By understanding how tsunami monitoring operates, users can make more informed decisions during emergencies.
Preparedness Remains Essential
Even with sophisticated monitoring systems, preparedness remains critical. Understanding evacuation procedures, learning local hazards, and staying informed are important components of coastal safety.
Awareness and preparedness often work together to improve resilience during natural disasters.
Final Thoughts
Tsunami monitoring is a global effort involving scientific organisations, warning centres, monitoring networks, and emergency management agencies. Tsunami Shield helps make this information more accessible by monitoring recognised sources and presenting information in a user-friendly mobile experience.
Reliable information, awareness, and preparedness remain some of the most effective tools available for improving coastal safety and helping people make informed decisions during emergencies.
Frequently Asked Questions
Where do Tsunami Shield's alerts come from?
Tsunami Shield monitors information published by official scientific and warning organisations including the Pacific Tsunami Warning Center (PTWC), National Tsunami Warning Center (NTWC), United States Geological Survey (USGS), GeoNet New Zealand, Australian monitoring agencies, and the Global Disaster Alert and Coordination System (GDACS).
Does Tsunami Shield create its own tsunami predictions?
No. Tsunami Shield does not predict earthquakes or tsunamis — earthquake prediction is not currently possible. Tsunami Shield monitors information published by official monitoring organisations and delivers that information to users in a timely, accessible way.
Why does Tsunami Shield use multiple data sources?
No single organisation monitors every hazard around the world. Using information from multiple recognised scientific and warning organisations helps improve coverage, resilience, and the reliability of the information delivered to users.
What should I do if I receive a tsunami alert through Tsunami Shield?
Always follow evacuation orders and guidance from local authorities immediately. Move to higher ground or inland as directed. Do not wait to confirm the alert before acting — official tsunami warnings should always be taken seriously.
