Time–space plots of very low frequency earthquakes (VLFEs) and low-frequency earthquakes (LFEs). a Time–space plot of VLFEs in the Okinawa area from April 2004 to December 2015. Blue dots denote the VLFEs. The catalog of the VLFEs is based on Nakamura and Sunagawa (2015) with later events added. Vertical lines with yellow stars show the SSE faults (Nishimura 2014). Gray hatched areas show the periods for which the analyses of the LFEs were calculated. b Same as a but for LFEs. Red colors show the LFEs. c Same as a but for the Yaeyama area. d Same as b but for the Yaeyama area. Blue stars show the occurrence dates of SSEs in the Yaeyama area cataloged by Nakamura and Sunagawa (2015)
