Its a long way from Tonga to Lauder. About about 3000 km. A huge underwater volcanic eruption on 15 January rocked Tonga and the surrounding region. The main blast was at about 5:26 pm local time. It spawned tsunamis seen around the world and sent an ash cloud 12 miles (20 km) high, or in excess of 100,000 feet - about 30 km - according to another
Volcanic eruptions are an interesting wildcard when it comes to climate. Thank you for this
Glad to be of help. Luckily their risk to ozone will diminish as atmospheric chlorine levels continue to decline ...
