The Active Supervolcano in Africa; The Awasa Caldera

Within Africa is an often forgotten about supervolcano which is considered to be active. Known as the Awasa Caldera, it and the associated Corbetti Caldera have each been the site of at least one volcanic eruption during the Holocene epoch. Specifically, the Corbetti Caldera has even been the site of recent magmatic uplift, which is quite common and not truly noteworthy at active supervolcanoes such as Yellowstone and Taupo. Note: This video's thumbnail image displays what the caldera forming eruption of the Awasa Caldera approximately 1.1 million years ago might have looked like. It does not display the current status of the Awasa and/or Corbetti Caldera, as neither are currently erupting or showing any signs of unrest. They are not likely to erupt anytime soon given their current activity.
