Understanding the Miyazaki Earthquake: Analyzing Nankai Trough Dangers and Future Predictions

(Koji Seko: critic, essayist)

At 4:43 p.m. on August 8, an earthquake occurred within the Hyuga-nada Sea in Miyazaki Prefecture. Miyazaki skilled a seismic depth of lower than 6, however earthquakes affected all of Kyushu, with seismic depth ranges of two to five recorded in Kagoshima, Oita, Fukuoka, Kumamoto, Saga, and Nagasaki.

The magnitude of the earthquake itself didn’t appear to be that nice in comparison with the Noto earthquake that occurred on New 12 months’s Day this 12 months, however the truth that the entire of Kyushu was shaken made me suppose, “It is a unusual magnitude.” Nonetheless, the earthquake appeared to ease and he calmed down and stated, “For now, I am joyful.”

At round 7:15 p.m., the Japan Meteorological Company swiftly held a particular assembly of the “Nankai Valley Earthquake Evaluation Research Group” and introduced, with out incident, “Momentary Data on Nankai Valley Earthquakes (Large Earthquake Warning).”

I believed, “What is that this? It is the standard warning to be careful for sturdy tremors for a couple of week.” I took it nonchalantly.

However what occurred subsequent was troublesome.

This “warning” has brought on an enormous confusion and uproar all through the presumed epicenter space, stating that “the potential of a brand new large-scale earthquake occurring is comparatively excessive in comparison with regular occasions.”

In response to this “warning”, NHK, in addition to all business broadcasters, interrupted their common programming and reported as if the Nankai Trough earthquake was as a consequence of happen tomorrow.

The Nankai Melancholy earthquake is a large space with an epicenter that extends 500 km from north to south, from Suruga Bay in Shizuoka Prefecture to the Hyuga-nada Sea in Miyazaki Prefecture. (A melancholy is a protracted, slender underwater basin that’s stated to have brought on an earthquake.) It has a 70-80% likelihood of occurring inside 30 years.

I do not know the way the variety of useless or lacking in that case was decided, however it’s estimated to be 320,000.

Maybe as a result of Hyuga-nada is the southernmost (westernmost?) level of the epicenter space, the current earthquake is taken into account a part of the Nankai Trough earthquake, and the Japan Meteorological Company swiftly held a gathering and issued a warning for subsequent week. It seems to be issuing a “warning” to that impact.

Elevating the alarm, Nao Hirata, chairman of the Nankai Trough Earthquake Evaluation Research Group, stated: “There’s a excessive risk that a big earthquake near magnitude 9 will happen sooner or later. If a category 7 earthquake happens, it’s many occasions extra seemingly than ordinary.” “Intercourse shall be intense,” she stated, eliciting a way of disaster.

On this method, as soon as the nice “consultants” level out “potentialities” that will or might not exist, nobody can refute them. Consequently, a “mega earthquake alert” has been issued.
