Huge Hunga Tonga Volcanic Eruption Seen From Space

Tonga: Volcanic Eruption and Tsunami - Jan 2022.
After weeks of volcanic activity emitting ash, the Hunga Tonga Hunga Ha’apai underwater volcano in Tonga erupted violently on 15 January. The eruption is said to be one of the biggest in Tonga in the last 30 years, with satellite imagery indicating a 5 km wide plume of ash, steam, and gas, rising approximately 20 km above the volcano. The volcanic eruption generated a 1.2-metre tsunami that crashed ashore in coastal areas of Tonga’s capital, Nuku’alofa. The estimated population within 100 km of the volcano is 76,000 people. [...] Tonga has been blanketed by 1-2 cm of volcanic ash, affecting the majority of the country and impacting on water and food supplies. Air quality is also of concern. Power has been disrupted, and communications with Tonga are a challenge as regular phone lines are down, the internet cable from Fiji to Tonga seems to have been damaged, and satellite phones are only working intermittently. Alert level 4 remains active for the volcano, meaning that eruption hazards are confined to areas near or around the volcano. (UNICEF, 16 Jan 2022)
