Fig. 10From: Noise classification for the unified earthquake catalog using ensemble learning: the enhanced image of seismic activity along the Japan Trench by the S-net seafloor networkCross sections of automatically determined hypocenters. The cross-sectional view shows earthquakes occurring within 40 km of each line in Figs. 8 and 9. The automatically determined hypocenters of M ≥ 5 events are indicated by stars. The pink area represents the continental crust, green area represents the Pacific Plate crust, and the blue area represents the Philippine Sea Plate crust. The purple inverse triangles indicate the forearc segment boundary according to Bassett et al. (2016), and the green inverse triangles indicate the northeast limit of the Philippine Sea Plate according to Uchida et al. (2009). The blue inverse triangle indicates the trenchBack to article page
