Okinavska ploča je manja kontinentalna tektonska ploča na sjevernoj i istočnoj polutci koja se proteže od sjevernog kraja Tajvana do južnog rta otoka Kyūshūa.[1][2] Okinavska ploča odgovorna je za potrese, poput potresa na potresa na otoku Kikai 1911., i razne vrste sporih potresa, uključujući potrese niske frekvencije,[3] potrese vrlo niske frekvencije,[4] podrhtavanje,[5] i događaje sporog klizanja.[6]
Granice
Istočna strana Okinavske ploče čini konvergentnu granicu s Filipinskom pločom , tvoreći jarak Ryukyu i otočni luk koji tvori otočje Ryū Kyū. Okinavska ploča je sa zapadne strane omeđena Okinavskim jarkom, zalučnim bazenom i divergentnom granicom s pločom Jangce. Dio južne granice između ploče Okinawa i Filipinske ploče je bivša zona subdukcije koja sada prihvaća koso klizanje i na kojoj se dogodio Velikog tsunami u Yaeyami 1771. godine.[7][8] Sjeverna strana Okinawske ploče omeđena je Amurskom pločom.
