Fig. 3.From: Shallow inland earthquakes in NE Japan possibly triggered by the 2011 off the Pacific coast of Tohoku EarthquakeHypocenter distribution for the M 3.4 earthquake sequence near Lake Tazawa in central Akita. The bottom figure shows the epicenter distribution. Squares denote the seismograph stations in this area. Red lines show the surface trace of the active fault. The top figure gives the vertical cross-section for earthquakes lying within ±3 km of the line in the epicenter map. The inferred rupture plane is shown in bold on the focal mechanism.Back to article page
