Factors:
Very deep seismic shock for this region: M4.3 – Vanuatu region 2017-07-23 19:12:17 UTC at a depth of 637.1 km
New Moon
Note: Deep for Vanuatu. Do not know if the thermal energy will find and run up the usual NW channels along the fault leading up to shallow or become trapped.
A well suited and better teleconnection candidate: M4.5 – 42km WNW of Tenno, Japan 2017-07-24 02:15:01 UTC at a depth of 18.8 km
.2 of a magnitude difference,the Vanuatu event set the magnitude range for Japan. However, it does not alter this forecast.
The energy is headed to the NW, with M4.8 – 90km WNW of Panguna, Papua New Guinea 2017-07-23 23:26:52 UTC at a depth of 169.9 km a few hours later.
