The lava flow from the Nyiragongo flank fissure eruption towards Goma stopped at Buhene, a few hundred meters from the city limits. The nearby airport was not affected. A separate lava flow that headed east over unpopulated land towards Rwanda also appears to have stopped.
The approximately 8,000 people who had crossed the Rwandan border, meanwhile, spent the night in the Rubavu stadium, in schools or in the street. They crossed the steaming lava flow of Kibati on their way home on Sunday.

Still, authorities warned that the danger was not over and that seismic activity in the area could cause more lava flows.
Volcanologists from the OVG, which monitors Nyiragongo, have struggled to carry out basic checks on a regular basis since the World Bank cut funding amid allegations of embezzlement, although experts have said the timing of this eruption was impossible to predict.

In the Reykjanes Peninsula, the lava, after rapidly descending a drop of a hundred meters, now flows for about a kilometer in the flatter part of the Nátthaga Valley. It should spread out more slowly before passing the 15 meter lip at the southern end of the valley.
The western dam was also breached, without however presenting a massive discharge.
On May 24, the gaseous pollution will move northwards, around Keflavkik to pass over Snaefelness.
