An international appeal's been launched to help nearly half a million people who've fled the huge volcano eruption near Goma in the Democratic Republic of Congo.
Dozens of people have already died after Mount Nyiragongo began spewing rocks and lava on Thursday.
Althought the eruption seems to have stopped for now, there are still tremors which means it's extremely dangerous.
A huge stream of boiling lava is flowing right through the town, destroying everything in its path.
Witnesses say more than half of Goma's already been consumed by the lava.
Most people have managed to flee across the border but some are trapped.
Water supplies have been ruined because lava's flowed into Lake Kivu and pumping stations have been destroyed.
The British government has pledged a £2m emergency aid package.
