The first quake hit at a depth of 10 kilometres (six miles), 205 kilometres from Kirakira and 448 kilometres from the capital Honiara and the second shallow quake struck just over two hours later about 159 kilometres from Kirakira.
    
The Solomons have been rocked by several quakes of 6.0-magnitude or higher in recent days, with the most recent a 6.0 magnitude quake which hit the islands early yesterday, and a 6.9 magnitude tremor the day before. No major damage was caused by the earlier tremors.
    
The Hawaii-based Pacific Tsunami Warning Center said there was no threat of a Pacific-wide tsunami from today's tremors.
    
Geoscience Australia initially estimated the two latest quakes at the magnitudes of 7.1 and 6.9 but said they were unlikely to cause local tsunamis in the quake-prone region, in part due to their location.
