GNSSデータから得られた歪み速度を,弾性・粘性・塑性の各成分に分解することに(おそらく)世界で初めて成功した.また,東北沖地震のような巨大地震後には塑性歪みが停止することに基づき,日本列島の歪み速度パラドックスの見方を大きく改訂した.

フィリピン海プレートは日本列島下では大きく変形している一方,南海トラフで沈み込む前はほぼ無変形であることに着目して,フィリピン海プレートの最近数百万年間の短縮速度を求めた.得られた短縮速度は,中部地方〜西日本の短縮速度のプロキシ(代替指標)として用いることができると考えられる.

純粋な粘弾性物質と弾性–粘弾性層構造物質の振る舞いが本質的に異なることを,Fukahata & Matsu'ura (2006)で導出した解析解を基に,数値計算例付きで示した.例えば,粘性率が1019 [Pa s]のとき,名目上の緩和時間は5年弱だが,実際の緩和には(特に長波長の水平成分では)数百年以上かかることが了解される.

弾性–粘弾性体の変位の食い違い理論に基づくプレート沈み込みモデルにより,島弧の隆起や海溝の沈降は数値的には再現されていたe.g., Matsu'ra & Sato, 1989, GJI).一様な曲率をもつ断層の運動が変位は生じても変形は生じないことに着目することで,なぜ島弧の隆起や海溝の沈降が起こるのか,その物理メカニズムを明らかにすることに成功した.プレート境界が円弧とき,計算される島弧の変形速度がその曲率半径に厳密に比例することは20年近くも前から知っていたが,その謎が解けた.
