Tsunami from Japan's mega-earthquake could be more than 30 meters high

There is a lot of noteworthy information in the special advisory of the Japan Meteorological Agency (JMA) about the risk of a super earthquake in the Nankai Trench.

"The risk of earthquakes around the Nankai Trench, a submarine trench that runs along the Pacific coast, is higher than usual," the JMA warned recently. The Nankai Trench stretches about 700 km, from Suruga Bay off Shizuoka Prefecture to the Hyuganada Sea off Miyazaki Prefecture.

If a major earthquake were to strike the region, the damage would be devastating. Tsunami waves from the quake could exceed 30 meters near the epicenter. The JMA has urged residents to prepare for possible earthquakes for at least a week.

When an earthquake occurs near a coastal area, tsunami waves can reach the coast of Shizuoka, Wakayama, and Kochi prefectures within 2-5 minutes; tsunami wave heights can reach more than 30 m according to a 2012 estimate.

Chief Japanese earthquake expert Naoshi Hirata talks about the possibility of a major earthquake in the Nankai Trench in Tokyo on August 8.

When people feel the shaking, they need to evacuate to higher ground as quickly as possible.

In the worst-case scenario of a Nankai Trench earthquake, 231,000 people could die and economic losses could reach 207 trillion yen. The quake could plunge the entire country into crisis.

The Japanese government has instructed 707 cities, including Tokyo, to step up disaster preparedness measures.

The JMA's warning came as on the afternoon of August 8, southwestern Japan was shaken by a 7.1-magnitude earthquake that injured 14 people.

According to Japan News , JMA previously estimated that there is a 70%-80% chance of a super earthquake of magnitude 8-9 occurring along the Nankai Trench within the next 30 years.
