The activity of the volcano remains intense and continues from both the summit (lava lake in south pit) and from the SE rift zone (lava lakes and lava flows).
The summit lava lake has gradually risen again, but undergoes frequent changes as the field report below describes.

On the SE rift zone, the effusive eruption also continues strongly into its 5th month. The lava lake, which had formed above the main fissure vent since January, has been producing multiple smaller and larger lava flows around it, with the main flow feeding a growing, avast pahoehoe lava flow field expanding to the NE.
This first rift zone lake crusted over during early-mid May, but a new lava lake formed soon after at a location about 350 m to the east. At around the same time, a new breakout of lava started in early May and has been feeding a new flow field overlapping the previous one into NE direction, currently more than 1500 m long and over 500 m wide.

Field report 11-15 April 2017
With collaboration with Addis Abeba University, a group visited Erta Ale to observe both the summit and the new fissure eruption which has been started on 22 Jan 2017. Our geologist guide Enku produced the following preliminary report:
"The group has observed substantial changes compared to conditions described in the past report and activity in February/March 2017.
The old southern Lava Lake surface has begin to be observed and sat 50 m below the North crater rim and 40m below the east crater rim. On top of the crust stood two coalesced hornitos in the NE part of the southern crater. The hornitos estimated to be 7m high and emitted high temperature and pressure so2 – rich gas and momentarily contained/emitted glowing molten lava.
The Old Lava Lake has chilled within 200m diameter in nearly circular in shape and the level of the Lava Lake would change every 30 Minutes as there is frequent collapse of the surface and then again Lava tubes from the wall of the crater feed and fill the crater with rapidly fresh flow of molten lava.
The group has also observed continues fountain of Lava from the surface about 25m high.
The surrounding surface around the rim/mouth of the crater seems to be solidified very well and people can now walk around the rim and able to observe the activities in the old southern Crater Lake. That is great news and I am very much enthusiastic to witness this.
The North pit is still the strong and noisy degassing of so2 spouted from several small hornitos grown in the central part of the solidified crust.
The new recently fissure eruption that has undergone in 22 Jan 2017 was no development of substantial lava overflow or fountaining. Instead the level of the Lava Lake went down about 10m from the rim and only a small fountaining occurred during the night time which rises to 3m to the rim level.
Still it is impossible to approach the new fissure (Lava Lake) eruption from a near distance and you can make the observation only from ~700m distance in the Northern part of the caldera.
So to conclude the status of Erta Ale, this days the old southern Lava Lake has started to rise up to the solidified walls of the widened crater and the level is changing now and then frequently.
