Democratic Republic of Congo – Volcanic eruption, update (ECHO 31 May 2021)Mon, 31 May 2021 15:47

  • The number of earthquakes detected in the area of Nyiragongo volcano and the deformation rates have decreased slightly since 29 May 2021. However, seismic activity and ground deformation continue to indicate the presence of magma under the urban area of Goma with an extension under Lake Kivu.
  • An estimated 415,700 people have been displaced across several localities in Democratic Republic of the Congo (DRC) and across the border in Rwanda.
  • Authorities and humanitarian organisations are providing help for those most affected. The rehabilitation of the damaged water supply system in Goma is ongoing. The risk of a cholera outbreak remains. Twelve suspected cholera cases were reported in the health centre of Saké between 27 and 29 May. Saké hosts more than 56,000 displaced persons and most suspected cholera cases are among them.
  • The Copernicus Emergency Mapping Service () was activated on 23 May and seven maps have been produced so far.
  • On 29 May, the European Commission allocated EUR 2 million in emergency humanitarian funding for those affected by the eruption of Mount Nyiragongo.
Democratic Republic of Congo – Volcanic eruption, update (ECHO 28 May 2021)Fri, 28 May 2021 16:17

  • High seismicity and ground deformation due to the activity of Mount Nyiragongo are still occurring in the Goma area. At least 140 earthquakes with magnitude up to 4.8 M have been recorded in the area, including in neighbouring Rwanda, since the volcano started erupting.
  • Authorities gave order for the evacuation of parts of Goma city on 27 May, but people from other parts are also moving or planning to move, given the seismic activity. In total an estimated one million people are concerned. In addition, people are also moving towards the cities of Bukavu and Saké as well as to Rubavu district just across the border in Rwanda.
  • Authorities in the Democratic Republic of the Congo (DRC), Rwanda and humanitarian aid organisations are scaling up their efforts for emergency assistance to the displaced who are in urgent need of shelter, food, water, sanitation, hygiene, health services, psychosocial support, protection, etc.
  • The Copernicus Emergency Mapping Service (EMSR513) was activated on 23 May and four maps have been produced so far. 
Democratic Republic of Congo – Volcanic eruption update (ECHO 26 May 2021)Wed, 26 May 2021 15:54

  • The eruption of Mount Nyiragongo, located 15 km north of Goma City, is still ongoing and significant seismic activity have been occurring in the area of the volcano causing some damage to buildings in Goma and in neighbouring Rwanda, notably in the Rubavu district (also affected by lava and many buildings have collapsed).
  • According to UN agencies, the number of deaths has risen to 32, at least 20,952 people are displaced and 40 people are still missing. In addition, the airports of Goma and Bukavu (100 km south-west of Goma) remain closed due to the ashfall. 
  • National authorities and humanitarian partners are still assessing damages and starting to conduct response activities. Main identified needs are shelter, access to clean water and sanitation, food, mental health and child protection (as many children have been separated from their parents).
Democratic Republic of Congo – Volcanic eruption update (ECHO 25 May 2021)Tue, 25 May 2021 16:41

  • The explosive and effusive activity of Mount Nyiragongo continues. A south-moving ash plume of 6,100 m has been recorded on 25 May. Seismic activities have been occurring and have also been recorded in the city of Goma, 15 km away from the volcano.
  • The eruption from the flank of Mount Nyiragongo on 22-23 May, created a lava stream that finally spared Goma, but destroyed four villages north of the city. At least 15 people have reportedly died, more injured, and approximately 30,000 have been displaced. Around 8,000 have fled to neighbouring Rwanda.
  • The lava flow has destroyed some of Goma’s water infrastructure, leaving around half a million people without water. There is an increased risk of a cholera outbreak. The affected population also requires psycho-social support. Authorities and humanitarian organisations are providing first assistance to the most affected. The Congolese Prime Minister called for an emergency meeting of the national committee for humanitarian coordination and relief organisations to lead the humanitarian response.
  • The European Union, including its humanitarian team based in Goma, continues to monitor the situation closely. The European Commission's emergency mapping service Copernicus () was activated on 23 May to support the damage assessment.

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.
