Chinese businessman Yu Hongtao is in Tonga. During his interview with CGTN, he said dust is everywhere on the island.

"What I've seen so far is everyone is involved in emergency rescue and disaster relief operations," Yu said. 

"Almost everyone is wearing a mask. Volcanic ash is on the streets because the ashfall lasted several hours. The ground is covered in ash, including vegetation and people's houses." He said volunteers have also been clearing up the roads.
