The Komsomolets anomaly (Figure A49) is located below northernmost Asia within the deep mantle and was not previously defined. It is E-W trending and its shallowest and easternmost location it may connect to the Chukchi slab (section 3.28). Based on … Continue reading →
The Kamchatka-Kuriles anomaly (Figure A48) is located below the Sea of Okhotsk and is interpreted to represent a slab that is still subducting at the Kamchatka-Kuriles subduction zone, penetrating down to the upper part of the lower mantle. We previously … Continue reading →
The Kalimantan anomaly (Figure A47) is located below southeast Asia from the middle to the upper part of the lower mantle (Widiyantoro and van der Hilst, 1996a; 1997; Rangin et al., 1999; Replumaz et al., 2004; Hall et al., 2008; … Continue reading →
The Kabylides anomaly (Figure 46) is located in the upper mantle below the north African margin of Algeria and was first identified by Spakman and Wortel (2004). It dips steeply, resting on the 660 km discontinuity, and is interpreted as … Continue reading →
The Juan de Fuca anomaly (Figure A45) is located below western North America, is N-S trending and is interpreted to be the still-subducting slab at the Cascadia subduction zone. In tomographic studies it has been imaged to depths of 250-400km … Continue reading →
The Izu-Bonin anomaly (Figure A44) is interpreted to reflect Pacific lithosphere that subducted beneath the Philippine Sea Plate. It is well-imaged in seismic tomographic models of van der Hilst et al. (1991), Bijwaard et al. (1998), Gorbatov and Kennett (2003), … Continue reading →
The India anomaly (Figure A43) is located below India. The India anomaly was classified by Van der Voo et al. (1999b) as the ‘II’ anomaly, by Replumaz et al. (2010c) as the ‘TH’ anomaly, and it was also identified by … Continue reading →
The Idaho anomaly (Figure A42) is located below western North America from the deep mantle up to upper part of the lower mantle. It was interpreted as the Idaho slab by van der Meer et al. (2010) and corresponds to … Continue reading →
The Hudson anomaly (Figure A41) is part of the set of anomalies commonly, also in our previous compilation in van der Meer et al. (2010), referred to as the Farallon slab, initially defined by Grand et al. (1997). It is … Continue reading →
The Hispaniola anomaly (Figure A40) is detached and located below the island of Hispaniola in the northern Caribbean region, at a depth of 800-1400 km. It was first identified by van Benthem et al. (2013), who interpreted it as the … Continue reading →
