URGENT: Japan on High Alert as M6.9 Quake Triggers Nankai Trough Investigation
By Timmy
A significant earthquake sequence off Japan's Miyazaki Prefecture has triggered urgent concerns about potential larger seismic events, leading the Japan Meteorological Agency (JMA) to launch an emergency investigation into the Nankai Trough region.
The seismic activity began at 21:19 JST with a powerful magnitude 6.9 earthquake striking the Hyuga-nada Sea at a depth of 30 kilometers, prompting immediate tsunami warnings. The mainshock was followed by a series of aftershocks:
• 21:29 JST - M4.1 (20km depth)
• 21:35 JST - M3.9 (20km depth)
• 21:42 JST - M4.1 (20km depth)
• 21:53 JST - M3.4 (30km depth)
In response to this seismic sequence, the JMA has initiated an urgent investigation into the possibility of a major earthquake along the Nankai Trough, a significant subduction zone capable of generating catastrophic seismic events along Japan's Pacific coast.
CURRENT ADVISORIES:
Tsunami warnings remain in effect
Residents should evacuate to higher ground in coastal areas
Continue monitoring official channels for updates
Review emergency preparedness plans
Keep emergency supplies ready
Maintain charged communication devices
The situation remains dynamic, with authorities closely monitoring seismic activity. Residents are urged to follow all official guidance and stay alert for further updates from the JMA.
