From: Relationship of preseismic, coseismic, and postseismic fault ruptures of two large interplate aftershocks of the 2011 Tohoku earthquake with slow-earthquake activity

Figure 1

Comparison of the total slip distribution of the 2011 off Iwate earthquake estimated in this study (0.2 m contour interval) with the spatial distributions of slow earthquakes and other related observations5: tremors (red squares), VLFs (yellow squares), earthquake swarms (blue circles), and repeaters (orange stars). The black star indicates the epicenter of the 2011 off Iwate earthquake. The characteristic distributions of slow earthquakes are outlined by dark-green dashed circles. The red crosses denote the epicenters of the seismicity in the period between the 2011 Tohoku earthquake and the 2011 off Iwate earthquake. The brown star indicates the horizontal location of the repeating-earthquake sequence off Kamaishi9,10. The broken gray lines indicate the isodepth contours of the upper boundary of the Pacific plate 30 with a 10 km interval. The gray contours and gray star in the upper left inset indicate the total slip distribution of the 2011 Tohoku earthquake41 and its epicenter, respectively (contour interval of 4.3 m). This figure was rendered by Generic Mapping Tools (GMT)42 4.5.14.
