The Solomon Islands Disaster Management Office says it's yet to receive any reports of damage or casualties from what it describes as a magnitude 7.5 earthquake last night.
The quake struck just after 8.30pm local time at a depth of about 60 kilometres, some 100 kilometres southwest of Makira.
A member of the New Zealand Red Cross, who's in Solomon Islands helping to improve the emergency communications system, says the full extent of the quake's impact is unknown.
Steve Davies says that locally, the process of gathering information after such a natural event is still slow.
"It's early days for everyone. Obviously the nature of the geography here - dispersed islands - (makes it) hard to get that information in. It takes a while before people can actually see what the damage is and then get it through the various communication systems such that they are."
