Updates on volcanic activity (Smithsonian)
The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Nyiragongo report has been published on 02 Jun 2021 09:06.
Satellite data and analysis indicated that the lava flows at Nyiragongo during 22-23 May were the result of a N-S trending dike that had intruded beneath the volcano and Goma, and likely extended beneath Lake Kivu. Though lava effusion ceased, intense seismicity continued afterwards and indicated the dike continued to be active, according to GeoRiskA. Ground cracking in the city and damage to buildings from earthquakes continued to be reported. On 27 May authorities mandated an evacuation of the at least 400,000 residents in higher risk areas (about 10 districts) according to news organizations. The total population of Goma is an estimated 670,000 people. Photos in news articles showed masses of people and cars jammed for kilometers on roads leading out of the city. During 28-29 May GeoRiskA reported that seismicity began to decrease and continued a downward trend at least through 1 June; both the seismic data and GPS data indicated that the dike was no longer propagating. A news article noted that residents had begun returning to their homes within a few days.
Humanitarian organizations noted that within five days after lava flow stopped nearly 700 children had been re-united with their families, and more than 200 were in foster care or other transitional facilities. More than 170 families continued to search for missing children. The eruption had destroyed 3,629 homes, 12 schools, and 3 health facilities. More than 20,000 people were displaced and 31 had died. Goma?s international airport remained closed, though one across the border in Rwanda was operating.
