Heard Island volcano news & activity updates

Heard island volcano (Australia): satellite images confirm active lava flows since Dec 2012

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.

Satellite images showing activity at Heard Island in recent months (Smithsonian / GVP)
Tuesday, Mar 26, 2013
The Smithsonian / GVP monthly Bulletin of the Global Volcanism Network for Jan 2013 confirms that Heard Island volcano is in eruption. A series of satellite images compared side by side show that the volcano started to produce lava (over-)flows from the summit crater of the Mawson Peak on the SE flank since December past year.

A significant heat source continues to show up on MODIS satellite data. A recent (9 March) EO1-Hyperion (NASA) satellite picture shows what could be a lava lake in the summit crater of Mawson Peak. ... [meer...]
Terra / MODIS satellite image with Heard island on 17 March 2013. Note the dark spot west (left) of the summit, likely a fresh lava flow.
Monday, Mar 18, 2013
A significant hot spot continues to be detected at the summit crater of Heard volcano. A recent Terra / Modis satellite image of parts of the volcano (which usually is completely hidden under clouds) shows a dark area immediately to the west of Mawson Peak. This could correspond to a fresh lava flow. [meer...]
