Predictions of earthquakes registering over M5, seismic intensity 4: Until May 30 2017
We will publish some parts.
Latest Earthquake Activity
- Increase in the number of M5 earthquakes occurring in Eastern offshore of Hokkaido.
- Over 1,000 earthquakes continue to occur in the Pacific side of the Tohoku Region.
- Frequent occurrences of micro earthquakes continues in “Northern Ibaraki, Offshore Wakayama, Kumamoto”.
- Increase in the number of earthquakes in Hyuganada.
- Earthquakes registering over M5 occurred in NE offshore of Okinawa Main Island and Offshore Taiwan.
Latest Crustal Movement
- Middle scale crustal movement observed in “Toyohashi2”.
- Large crustal movement observed again this week in “Ioto2”.
- Small scale crustal movement towards “Hyuganada direction” observed in “Miyazaki”.
- Large northeastward crustal movement observed in “Chatan, Okinawa”.
This week’s crustal movement: Kyushu■Large crustal movements seen prior to a major earthquake were not observed.
M4-5 class earthquakes are predicted because the number of micro earthquakes with shallow hypocenters are increasing after the occurrence of a shallow M3 class earthquake in Hyuganada. Around Kumamoto, earthquakes occurred 472 times/week (3 weeks ago), 351 times/week (2 weeks ago), and 300 times/week (last week), as aftershocks of last year’s Kumamoto Earthquake. Also, the “cracks in the ground” observed in 58 locations of Bungo-Ono-shi, Oita are likely effected by last year’s Kumamoto Earthquake. As a result, the possibility of a M4 class earthquake to occur from Kumamoto through Oita area remains. * From the decrease of groundwater level observed a week prior to the Kumamoto Earthquake, and decrease of groundwater level observed in multiple points of Bungo-Ono-shi after the discovery of these cracks, they are presumed to be caused by the change in underground water vein.
