Iceland Volcano's Fountain of FirePeople stand silhouetted as lava spurts from Iceland's Eyjafjallajökull (pronounced AY-uh-full-ay-ho-kul) volcano on March 30, 2010—part of the ongoing eruption that started on March 21. (See more pictures of the Iceland volcano eruption.)

Bursting to life after 190 years, the glacier-capped volcano has drawn swarms of tourists eager to witness proof of Iceland's reputation as the land of fire and ice. Police estimate that more than 25,000 onlookers have visited Eyjafjallajökull since the volcano started erupting, according to the Reuters news service.

But tourists and residents still have reason to be wary: On Wednesday officials reported that the Iceland volcano eruption had opened a new fissure about 980 feet (300 meters) long that's spewing lava. Geologists think the new vent means that volcanic activity will start appearing farther north, endangering a wildlife reserve that's a popular tourist attraction, Reuters reported.
