Transformation of juvenile Izu–Bonin–Mariana oceanic arc into mature continental crust: An example from the Neogene Izu collision zone granitoid plutons, Central Japan
2017, LithosCitation Excerpt :The Izu Collision Zone granitoid plutons provide an exceptional example of collision-induced transformation from juvenile oceanic arc to mature continental crust in an ongoing arc–arc collision zone. The Izu Collision Zone is located near the Boso triple junction (Ogawa et al., 1989), where the northern end of the IBM arc has been colliding with the Honshu arc as a consequence of the northwestward migration of the Philippine Sea Plate (Fig. 3a). The collision has been occurring since the Middle Miocene (ca. 15 Ma, Niitsuma, 1989; Soh et al., 1991; Takahashi and Saito, 1997), nearly coeval with the onset of clockwise rotation of the southwest Honshu arc during the opening of the Japan Sea (17–15 Ma, Otofuji et al., 1994).
Tsunami vulnerability assessment in the southern boso peninsula, Japan
2014, International Journal of Disaster Risk ReductionCitation Excerpt :The Boso Peninsula is located in East Japan and to the north of the Sagami Trough. The Sagami Trough is a structure of complex bathymetry with various basins, small troughs and knolls, occurring from the tectonic activity of the Boso Triple Junction [14], and has been characterised as one of the most seismically active locations in Japan [10]. There have been several earthquakes with magnitudes 7–8 in the region [13] with the biggest ones in historic times being the M8.2 earthquake of 1703 and the 1923 M7.9 Kanto earthquake [9].
Scattering of teleseismic P-waves by the Japan Trench: A significant effect of reverberation in the seawater column
2014, Earth and Planetary Science LettersCitation Excerpt :Then, we calculated the average and standard deviation of the location of the scatterer for each apparent velocity. The maximum semblance value was calculated for an apparent velocity of 3.5 km/s (in good agreement with the observed apparent velocity) and was located at 141.25E, 34.8N (Fig. 6a), near the Boso triple junction where the North American, Pacific, and Philippine Sea plates meet (Ogawa et al., 1989). Although the estimated location and its standard errors depend on an assumed velocity of 3.5 km/s, the locations determined using different assumptions of apparent velocity differ by less than 100 km, and with uncertainties of ∼20 km for the highest semblance values, which is much less than the width of the Japan Trench.
Progress of illitization along an imbricate frontal thrust at shallow depths in an accretionary prism
2013, TectonophysicsCitation Excerpt :The main body of the Miura–Boso accretionary prism, exposed around Tokyo Bay in central Japan (Fig. 1a), consists of the Miura Group (the Misaki Formation on Miura Peninsula, and the Nishizaki Formation on Boso Peninsula) (Fig. 1b). The Miura Group sediments are mostly made up of island–arc volcaniclastics, which are presumed to be deposited on the deep sea of the Izu–Arc, and then accreted to the Honshu arc along the Sagami Trough (Fig. 1a; Hanamura and Ogawa, 1993; Lee and Ogawa, 1998; Ogawa et al., 1985, 1989). The collision of the Izu block with the Honshu arc (~ 1 Ma) is thought to cause clockwise rotation and rapid uplift of the Nishizaki Formation (Yamamoto and Kawakami, 2005; Yamamoto et al., 2005).
