Japan’s Earthquake and Tsunami Warning Systems
Japan is famous for its state-of-the advanced disaster management techniques. Here’s how Japan stays well-prepared before, during, and after earthquakes.
The Role of JMA (Japan Meteorological Agency)
The JMA is monitoring seismic activity 24 hours a day and issues warnings about earthquakes and tsunamis for the risk of losing life and property.
Earthquake Warnings
JMA detects the beginning earthquake waves (called P-waves) prior to destruction waves (S-waves) arrive. This system can provide just a few seconds to one minute of warning that may seem brief, however it could save lives by stopping trains and opening doors to elevators, and delivering warnings.
Tsunami Warnings
In the event that an earthquake beneath the ocean is recorded and it is detected, the JMA examines the possibility that it could cause tsunamis. The coastal areas are immediately alerted via loudspeakers and broadcasts on TV, and mobile alerts. The warnings include estimated waves and arrival times. This allows residents to leave.
How Alerts Reach the Public
Alerts are distributed quickly through:
Smartphone Alerts (automatically delivered to all phones in the affected regions)
Broadcasts from TV and Radio (interrupting the regular program)
Community Loudspeakers (common in villages and towns)
Public Alert Systems installed in hospitals, schools and offices
