Pacaya (Guatemala) [2]: A surge in activity with increased strombolian explosions and the effusion of a lava flow occurred during 4 hours on 30 July, similar to the event from 30 May.
Explosions from the Mackenney crater reached heights of 250-300 m and a new lava flow started to flow onto the south side of the mountain through a deep notch in the crater.

The activity only lasted 4 hours, after which explosions almost disappeared and the lava flow ceased again.


Heard (Australia, Southern Indian Ocean) [3]: Recent satellite images suggest that a lava lake is most likely currently active in the summit crater of Mawson Peak.
NASA satellite infrared images show a very hot circular object of about 100-150 m in diameter that plausibly could only be produced by the strongly heat-radiating surface of a lava lake. Currently, no lava flows seem to be present on the other hand.
