Japan’s Seafloor Monitors May Unlock Secrets of Megaquakes

Speedy Summary

• Japan has developed new seafloor monitoring technology to study the Nankai Trough, a dangerous tectonic area known for causing devastating earthquakes.
• The advanced network could perhaps provide up to 20 minutes of warning in case of tsunamis triggered by seismic activity.
• Researchers are focused on understanding “slow-slip earthquakes,” which may contribute to larger and more destructive quakes.

Indian Opinion Analysis

The advancement of Japan’s seafloor monitoring system is a significant advancement in disaster preparedness,with implications for global earthquake-prone regions,including India.While India’s coastline is not directly linked to the Nankai Trough, lessons from Japan’s proactive measures can help enhance India’s own seismic and tsunami warning infrastructure, especially along vulnerable zones such as the Andaman and Nicobar Islands or areas around the Indian Ocean plate boundary.A 20-minute advance warning could drastically improve evacuation efforts and save lives in similar high-risk zones.

adaptation of such technologies or international collaboration could strengthen India’s disaster management systems while fostering resilience against natural calamities in an increasingly uncertain environment caused by tectonic shifts globally.
