Fig. 1From: Estimating errors in autocorrelation functions for reliable investigations of reflection profilesSeismic network of MeSO-net (triangles) and Hi-net (squares) stations. Blue, red, and purple triangles represent the stations used for the ENE–WSW profile, ESE–WNW profile, and both profiles, respectively. Circles represent the hypocenters of \(M\ge 2\) earthquakes at depths greater than 80 km from May 16, 2008, to June 30, 2021, from the unified catalog of the JMA; brown indicates earthquakes used in this study. Stars indicate the hypocenters of the earthquakes used in Fig. 2Back to article page
