The Wichita anomaly (Figure A91) is located below central North America from the core-mantle boundary up to deep mantle. It was first described in van der Meer et al. (2010), where we interpreted the anomaly as the Wichita slab that … Continue reading →
The Venezuela anomaly (Figure A90) is located below northern South America from the mid-mantle up to the upper part of the lower mantle. It was first identified in van der Meer et al. (2010). It was interpreted as the sGAC … Continue reading →
The Ushky anomaly (Figure A89) is located below northeast Asia in the upper mantle and uppermost part of the lower mantle. It is E-W trending and at ~920 km depth it connects to the N-S trending Sakhalin slab in the … Continue reading →
The Trans-Americas anomaly (Figure A88) is located below the Cocos plate and Central America from the core-mantle boundary up to the deep mantle. It has been detected in previous seismological (Niu and Wen, 2001; Thomas, 2004; Hutko et al., 2006; … Continue reading →
The Tonga–Kermadec–Hikurangi anomaly (Figure A87) is located below the south Fiji Basin in the upper mantle and the upper part of the lower mantle up to a depth of ~1200 km. It was interpreted in the uppermost lower mantle as … Continue reading →
A north–south trending belt of positive wave-speed anomalies under the central Pacific Ocean has been interpreted to represent a series of Triassic-Jurassic intra-oceanic subduction zones, called the Telkhinia subduction zones by van der Meer et al. (2012) (Figure A86). These … Continue reading →
The Sunda anomaly (Figure A85) was previously imaged by Widiyantoro and van der Hilst (1996; 1997), Replumaz et al. (2004), Spakman and Hall (2010), Pesicek et al. (2010), Widiyantoro et al. (2011), Fukao and Obayashi (2013), Koulakov (2013), Zahirovic et … Continue reading →
The South Orkney Island anomaly (Figure A84) is NW-SE trending and is located in the mid-mantle, from below southeastern Patagonia to below the Weddell Sea. Based on the shallower Scotia slab and the Georgia Islands slab to the east, it … Continue reading →
The NW-SE trending South Loyalty Basin anomaly (Figure A83) is located below the Tasman Sea within the upper part of the lower mantle. It was first identified by Schellart et al. (2009). In the east, the flat-lying South Loyalty Basin … Continue reading →
The Socorro anomaly (Figure A82) is located below western North America within the mid-mantle. It was first described in van der Meer et al. (2010) and corresponds to anomaly CR-3 of Sigloch and Mihalynuk (2013). The Idaho slab and the … Continue reading →
