The Cumbre Vieja volcano has damaged hundreds of homes and forced more than 6,000 people to evacuate as lava raced across La Palma, part of the Spanish archipelago known as the Canary Islands.
The volcano, which had not erupted in nearly two decades, caused thousands to flee, many across the border to Rwanda. But the lava didn't appear to be flowing toward Goma, a city of nearly 2 million.
St. Vincent's National Emergency Management Organization raised the island's alert to red on Thursday, after days of increased seismic activity at the La Soufriere volcano.
Indonesia, an archipelago of 270 million people, sits along the Pacific "Ring of Fire," which leaves the country prone to earthquakes, tsunamis and eruptions.
