Videos captured by Tongan geologists show a huge ash cloud rising over the island nation during a powerful volcanic eruption that caused a tsunami in the Pacific.
Tonga finished removing a thick coat of ash from an international runway on Wednesday after days of painstaking effort, clearing the way for desperately needed emergency aid to arrive in the isolated and disaster-stricken nation.
Local authorities were only able to clear about 100-200 metres of the runway per day.
