Fig. 1From: Periodic upward migration model for intermediate-depth earthquakes in Vrancea, RomaniaLocation of Vrancea intermediate-depth earthquakes. (a) Earthquakes with M ≥ 6.0 earthquakes that occurred during 1500#x2013;2000 in Romania (data from ROMPLUS catalog). Almost all earthquakes are intermediate-depth earthquakes in Vrancea. (b) Relocated 4 M ≥ 6.9 earthquakes and proposed seismic gap (obtained from figure 6(b) shown in Hurukawa et al., 2008).Back to article page
