It seemed like yesterday, the day I first discovered volcanic winter while conducting research on the infamous 1993 “storm of the century,” and some passing weather enthusiast had brought up ...

This is a repost from the archives, an older post by Henrik which has been updated to reflect more recent findings. Did you know there are 255 volcanoes or volcanic features listed in the US?

The most common origin of pillow lavas is a mid-oceanic spreading centre. That has also been suggested for the Barberton rocks. But it has been questioned. The eruptions began 3.54 Gyr ago and lasted ...

The centre of South Africa is an amazing place. The long drive from Cape Town in-land is exciting for the first two hours, while the road climbs up through the mountains, past vineyards and valleys ...

The Afar Triangle The double-booked land is also known as the Afar Triangle, a low-lying region wedged into the Ethiopian Plateau. The region is not for the intrepid. The name is synonymous with ...

Lewotobi Laki-laki erupts quite regularly, on average about once a decade. These eruptions can last a long time: 6 months is not unusual and the 1921 eruption lasted almost a full year. On the VEI ...

The rivers feed the same large body of water at their terminus, though with different entry points. The original Aral Sea is (or was, around 1960) a brackish-water lake covering an area of 67,499 km 2 ...

The Tasman rift gave rise to a new phase of volcanism. Most of this ended up on the inaccessible, submerged Lord Howe Rise. However, Australia kept some basalt flows and dikes, which are visible ...
