Abstract
We developed fault models of the mega earthquakes along the Kuril-Kamchatka Trenchand predicted strong ground motions at Kushiro, Urakawa, and Tomakomai based on
empirical Green’s function method using these models. Spectral inversion analysis wasperformed for elemental earthquakes used as empirical Green’s functions to estimate theirsources and paths parameters. To verify the validity of the predicted strong ground motions,
we compared them with the observation records of the 2003 Tokachi-oki earthquake andwith a previous ground motion prediction equation. Finally, we evaluated the impacts of thepredicted strong ground motions on seismically-isolated buildings based on dynamicresponse analysis.
Key Words: Kuril-Kamchatka Trench, Fault Model, Strong Motion Prediction, Isolated Building࣮࣮࢟࣡ࢻ㸸༓ᓥᾏ⁁㸪᩿ᒙࣔࢹࣝ㸪ᙉ㟈ືண 㸪ච㟈ᘓ≀1㸬ࡣࡌࡵ࡟ᆅ㟈ㄪᰝ◊✲᥎㐍ᮏ㒊(2017)1)ࡣࠊ༓ᓥᾏ⁁ἢ࠸࡛Ⓨ⏕ࡍࡿྍ⬟ᛶࡢ࠶ࡿᕧ኱ᆅ㟈ࡢ㛗ᮇホ౯ࢆᐇ᪋ࡋࠊᑗ᮶ࡢᆅ㟈ࡢⓎ⏕ࣃࢱ࣮ࣥࢆᥦ♧ࡋࡓࠋෆ㛶ᗓ (2020)2)ࡣࠊࡑࢀࡽࡢ㟈※ീ࡟ᑐࡋ࡚ᙉ㟈ື⏕ᡂᇦ࠿ࡽᡂࡿ᩿ᒙࣔࢹࣝࢆタᐃࡋࠊ⤫ィⓗࢢ࣮ࣜࣥ㛵ᩘἲ࡟ࡼࡿᙉ㟈ືணᇶ࡙ࡃ㟈ᗘศᕸࢆබ⾲ࡋࡓࠋࡋ࠿ࡋ࡞ࡀࡽࠊࡑࡢண⤖ᯝ࡟ᆅ㟈ືࡣබ⾲ࡉࢀ࡚࠸࡞࠸ࠋࡇࢀࡽࡢᆅ㟈ືࡀᵓ㐀≀ࡢ⪏㟈ᛶ⬟࡟ཬࡰࡍᙳ㡪ࢆヲ⣽࡟᳨ウࡍࡿࡓࡵ࡟ࡣࠊධຊᆅ㟈ືࡢ᫬้Ṕࡀᚲせ࡛࠶ࡿࠋຍ࠼࡚ࠊ⤫ィⓗࢢ࣮ࣜࣥ㛵ᩘἲࡣ࿘ᮇ 2㹼3 ⛊⛬ᗘ௨ୗࡢ▷࿘ᮇᖏᇦࢆᑐ㇟࡜ࡋࡓᆅ㟈ືホ౯ᡭἲ࡛࠶ࡿࡓࡵࠊච㟈ᘓ≀ࡢࡼ࠺࡞㛗࿘ᮇᵓ㐀≀࡟ᑐࡋ࡚ࡣࠊ࿘ᮇ 4㹼6 ⛊⛬ᗘࡲ࡛ࡢ㛗࿘ᮇᖏᇦࡶ㐺ษ࡟ホ౯࡛ࡁࡿᡭἲࢆ㑅ᢥࡍࡿᚲせࡀ࠶ࡿࠋ41
