A bright bolt of lightning crackles within the ash cloud from the eruption of the Eyjafjallajökull volcano in Iceland in April 2010. Volcanic lightning occurs when roiling ash particles rub against each other and become electrically charged
Mount Semeru, seen with an ash plume, is the highest volcano on the Indonesian island of Java and has been in a constant eruption since 1967. It lies at the southern end of the Tengger caldera, which contains smaller volcanoes Mount Bromo and Mount Batok (both seen in the foreground), and several others.
Perched above the lighted city of Catania, Italy, Mount Etna hurls a fountain of fire skyward as rivers of lava spill down its flanks. In spite of its dazzling displays, Mount Etna is a relatively safe volcano with rare, compact eruptions and slow-flowing lava that gives people a chance to escape.
A volcanic eruption and the eruption of light from charged particles in the atmosphere—called the Northern Lights—occur at the same time in Iceland. The island nation was created by volcanic activity and today has 35 active volcanoes, which provide the country with plentiful geothermal power.
