The Active Volcano in Eritrea; Dubbi

Within Africa is an area covered by lava which is approximately the size of Rhode Island. This lava field originates from a single volcano known as Dubbi that is located in the nation of Eritrea. Dubbi is a bimodal volcanic system that has produced long silica poor lavas and highly explosive rhyolite lavas. This volcano produced a famous and explosive eruption in 1861, and is likely to produce more eruptions in the future. This video will discuss this volcano in Eritrea, the Afar Triangle, and extent of its 1861 eruption.

Note: For some reason youtube would not allow me to place the correct citation (specifically the DOI) so I will put the full one in a pinned comment in the comments section below. Instead, here is the link to the original article: https://pubs.geoscienceworld.o....rg/gsa/geology/artic

The DOI is: 10.1130/0091-7613(2000)28(less than)91:LKHEIA(Greater than) 2.0.CO;2. But you replace (Greater than) and (less than) with the character symbols. For some reason YouTube isn’t allowing those characters.
