Fig. 7From: Real-time crustal monitoring system of Japanese Islands based on spatio-temporal seismic velocity variationSpatio-temporal velocity maps determined by using a–e the ARM and f–j the SRM. The ARM and SRM have different temporal resolutions because the current trace was made with stacking periods of 17 and 11 days, respectively. Both methods identified spatio-temporal velocity changes caused by the Kumamoto earthquake. But, the velocity changes derived from both methods are largely differentBack to article page
