Original article
Very strong subduction earthquake in the sea approx. 50 km from the islands of Guadalcanal and Makira.
The epicenter location is in line with the subduction faulting zone.
USGS has received 2 Felt reports from the greater epicenter area with a III to V MMI value. Both signals have been collected at least 130 km from the epicenter.
NO Tsunami bulletin has been released by NOAA
GDACS has published a GREEN tsunami report= very limited chance on damage and/or injuries
Following the theoretical calculations of the USGS a VI MMI (strong shaking) might have been experienced by 6,000 people.  116,000 islanders would have experienced a moderate V shaking and 320,000 people a light IV shaking.

Guadalcanal (Isatabu) is a tropical island in the South-Western Pacific. It is the largest island in the Solomons, and during 1942-43 it was the scene of bitter fighting between Japanese and Americans in which the latter were victorious. At the end of the war, Honiara, on the north coast of Guadalcanal, became the new capital of the British Solomon Islands Protectorate. Guadalcanal is mainly covered in tropical rainforest and jungle and it has a mountainous interior with an active volcano, Mount Popomanaseu. The population in 1998 was around 85,000. (Wikipedia)

The island of Makira (formerly San Cristobal) is the largest island of Makira-Ulawa Province in the Solomon Islands. The island is located east of Guadalcanal and south of Malaita. The largest and capital city is Kirakira. (Wikipedia)
