Tonga is calling for “immediate aid”, with an urgent need for fresh water and food, as it assesses the damage caused by Saturday’s eruption of the Hunga-Tonga-Hunga-Ha’apai volcano. Al Jazeera reports that the volcano exploded in a massive eruption on Saturday – said to be the biggest since Pinatubo in the Philippines in 1991 – triggering a tsunami and blanketing the Pacific island nation in volcanic ash. “Communications remain down and the full extent of the harm to lives and property is currently unknown. What we do know is that Tonga needs immediate assistance to provide its citizens with fresh drinking water and food,” Parliament Speaker Lord Fakafanua said in a statement shared on social media. The appeal came as experts detected large waves in the area on Sunday, which they said “might be from another explosion of [the] volcano”.
