The Red Cross reports that approximately 10,000 people were forced from their homes by the worst floods there in 28 years.
More than 50,000 in total have been affected by the disaster in the capital of Honiara and throughout the entire surrounding Guadalcanal province.
The storm also washed out roads and bridges, hampering relief efforts.
Ita strengthened to a Category 4 storm late in the week as it approached Australia’s northern Queensland state with maximum sustained winds of about 130 mph.
It was the most powerful cyclone to approach Queensland since Cyclone Yasi struck in 2011 as one of the most powerful such storms in the state’s recorded history.
Yasi inflicted $3.3 billion in damage and lost tourism earnings, according to official estimates.
