The temporal relationship between the interplate and inland earthquakes of Kyushu Island region was investigated. We analyzed this relationship by stacking the temporal frequency of the inland earthquakes with reference to the occurrence time of each major interplate earthquake in the Hyuga-nada region, that occurred between 1900 and 2000. A good coincidence of occurrence between the inland and the interplate earthquakes is recognized. While the tendency of the occurrence after the interplate events has already been pointed out, we found that the inland earthquakes also tend to occur before the interplate events. Abrupt activation of the inland earthquakes within several months before major interplate earthquakes is recognized in addition to the tendency to occurr afterwards. The preceding inland earthquakes may indicate that they are triggered by precursory slow slips around the hypocenters of the Hyuga-nada earthquakes.

@dogsguitar おっしゃるとおりです。2002年に論文が出ています。日向灘の地震と内陸直下はセットで、半年くらいでもう一方が起こる傾向があるそうです。ご参考までにどうぞ。 https://t.co/fWuA9MftJQ
先日のNHKスペシャルで日向灘で地震が起こると南海トラフの地震が起こる時期が早まるとか言っていてような。ちょっとGW中に備蓄見直そう。RT @usa_hakase: 日向灘の地震に先立つ九州内陸の地震(山岡ほか2002地学雑誌)https://t.co/lgK3N7aO6L
