FUKUOKA –
The Kego Fault Zone operating by central Fukuoka may produce an earthquake with a most seismic depth of seven, leaving 1,800 individuals useless, 800 disaster-related deaths and 319,000 evacuees, based on prefectural injury estimates, as specialists warn that an unruptured part could stay below stress.
The magnitude 7-level earthquake that struck Kumamoto on July 28 and registered a most depth of seven could have been influenced by a piece of the fault that didn’t rupture throughout the 2016 Kumamoto earthquakes. Specialists say an analogous sort of earthquake may happen in Fukuoka.
Mitsuteru Asai, a professor specializing in catastrophe prevention engineering at Kyushu University’s Faculty of Engineering, stated the most recent earthquake was linked to an unruptured part of the Hinagu Fault, which was concerned within the earthquakes 10 years in the past.
“The Hinagu Fault was deeply involved in this Kumamoto earthquake,” Asai stated. “During the first Kumamoto earthquake 10 years ago, the foreshock occurred at the northern end of the Hinagu Fault. The fault has remained under stress since then, and the central and southern sections that had not yet ruptured continued to be in a state where they could break more easily. One of those sections ruptured this time.”
The Kego Fault Zone, which runs by the middle of Fukuoka, is believed to face an analogous threat from an unruptured part.
The 2005 Fukuoka Prefecture Western Offshore Earthquake occurred within the northwestern a part of the Kego Fault Zone, however the southeastern part didn’t transfer and stays unruptured.
The authorities’s Headquarters for Earthquake Research Promotion classifies each the southeastern part of the Kego Fault Zone and the Hinagu Fault Zone as S-rank, its highest hazard class.
“The Fukuoka Prefecture Western Offshore Earthquake can be considered an event involving part of the Kego Fault, and the fault lies along its extension,” Asai stated. “People should understand that the Kego Fault is now in a state where it has been subjected to stress. In terms of seismic intensity, upper 6 and, depending on the location, 7 are entirely possible. I hope people learn from this Kumamoto earthquake that they need to prepare in their daily lives.”
Fukuoka Prefecture has estimated the injury that might happen if an earthquake originates within the southeastern part of the Kego Fault Zone.
The situation assumes a magnitude 7.7 earthquake with a most seismic depth of seven.
The prefecture estimates that 1,800 individuals could be killed, with an extra 800 disaster-related deaths. About 12,000 individuals could be injured, 319,000 could be compelled to evacuate, and 36,000 buildings could be fully destroyed or burned down.
The projections underscore the necessity for residents to acknowledge {that a} main earthquake may strike at any time and to deal with the hazard as a direct menace slightly than a distant risk.
