Effusive eruptive activity at the remote volcano continues. A recent satellite picture shows a new lava flow on the SW flank of Mawson Peak. A MODIS hot spot is visible as well.
Starting in October 2012, satellites measured subtle signals that suggested volcanic activity on remote Heard Island. The recent satellite images (NASA Earth Observatory) have now provided proof of an eruption otherwise likely undetected.
By April 7, 2013, Mawson's steep-walled summit crater had filled, and a trickle of lava had spilled down the volcano's southwestern flank. On April 20 the lava flow remained visible, and had even widened slightly just below the summit.
