A narrow, E-W trending, steeply north-dipping anomaly was described below the Hindu Kush region of North Pakistan, from deep earthquakes reaching 250 km depth (Pegler and Das, 1998; Pavlis and Das, 2000; Lister et al., 2008; Zhang et al., 2011) … Continue reading →
The Himalayas anomaly (Figure A38) is located below the northern part of the Indian continent from the upper part of the lower mantle up to the upper mantle. In previous tomographic studies it has been referred to as the IV … Continue reading →
The Hatteras anomaly (Figure A37) is part of the set of anomalies commonly, also in our previous compilation in van der Meer et al. (2010), interpreted as the Farallon slab, initially defined by Grand et al. (1997). It is located … Continue reading →
The Halmahera anomaly (Figure A36) corresponds to the A4 anomaly of Hall and Spakman (2002; 2004) and was previously imaged by Widiyantoro and van der Hilst (1997), Hall and Spakman (2015), and Wu et al. (2016). It is interpreted as … Continue reading →
A positive wave speed anomaly has been imaged below the Great Basin, Nevada (Figure A35), and was originally named the Nevada Cylinder (Roth et al., 2008). The Great Basin anomaly is located in the upper mantle below southwestern North America, … Continue reading →
The Gibraltar anomaly (Figure A34a) is located in the upper mantle below the Alboran Sea. Its base is resting on the 660 km discontinuity, and it is still connected to Atlantic crust in the west, is dipping eastwards and is … Continue reading →
The Georgia Island anomaly (Figure A33) is located below the southern Atlantic and Antarctic Oceans from the core-mantle boundary up into the mid-mantle, separated from the shallower Scotia slab (section 3.79). It is interpreted as a slab that appears to … Continue reading →
The East China anomaly (Figure A31) is located below eastern Asia from the core mantle boundary up into the deep mantle (~2000 km depth). At its shallowest point (~1700 km), it connects to Mongolia slab to the NW. Due to … Continue reading →
The Cyprus anomaly (Figure A30) was imaged by Faccenna et al. (2006) and Biryol et al. (2011) and is interpreted as a north-dipping slab that may or may not be still attached to the African lithosphere to the south of … Continue reading →
The W-E trending Chukchi anomaly (Figure A28) is located below North Siberia and the Chukchi Sea (Arctic Ocean) within the mid-mantle. At its base, at equivalent latitudes it is ocated in between the top of the Mongol-Kazakh slab towards the … Continue reading →
