The flank effusive eruption of the volcano continues at high levels and illuminates the sky over the capital city of Goma.
The new eruptive fissure vent on the eastern flank, as reported by observers in social media, is feeding fast-flowing lava flows - thanks to the volcano's extraordinarily fluid lavas at extremely low viscosity - that continue to advance towards Busambali, Byungo, Mudja province including Goma capital city and are expected to threaten inhabited areas.
The extremely fluid 1977 lava flows caused many fatalities, as did lava flows that inundated portions of the major city of Goma in January 2002.

Nyiragongo volcano (DR Congo): new flank eruption with large lava flows

A new flank eruption started at the volcano this afternoon. It seems that a fissure opened on the eastern(?) flank, and drained the lava lake inside the volcano.
Large lava flows can be seen on published imagery, but it seems that so far, the city of Goma, partially destroyed in 2002 during the last flank eruption of the volcano, is not threatened (yet).
The lava of Nyiragongo volcano is particularly fluid and therefore its lateral eruptions that produce fast-flowing lava flows are more dangerous than from most other volcanoes.

Nyiragongo volcano (DRCongo): lava lake level drops

The Observatoire Volcanologique de Goma (OVG) reported that during 1-31 July the level Nyiragongo's lava lake had dropped, making it not visible in the daytime. Incandescence from the lake continued to be visible at night. Activity also declined at a small eruptive cone that formed in the crater in 2014.
Flank vent remains active on eastern crater floor
Update Wed 13 Apr 15:59

The secondary vent remains active, a recent visit (on 8 April) at the volcano showed. Lava continues to be erupted from the side vent on the eastern crater floor and occasionally still cascades into the main pit with the active lava lake:

Activity from secondary vent ceases (?)
Update Sun 03 Apr 08:06
A recent visit to the volcano showed no more (or at least no more significant) activity from the side vent on the lower terrace. The recent lava flows that had surrounded the lips of the inner crater and partially spilled into the central lava lake were seen cooling.

Lava falls into central lava lake
Update Sat 26 Mar 17:06
The mainly effusive activity from the new secondary vent inside the volcano's caldera continues with little changes. By now, new lava flows have surrounded the central pit (containing the main lava lake), covered most of the lower platform and cascade into the central vent at multiple locations.
