Steaming lava blocks on 27 Nov 2011 near La Restinga (El Hierro) photographed from the air by Guardia Civil / INVOLCAN
Lava balloons are hollow gas-filled pieces of lava floating to the surface above effusive submarine vents. Many lava balloons have been produced and observed during the ongoing 2011-12 shallow submarine eruption at El Hierro.
Floating lava blocks could result from the detachment of pillow-lava edges followed by the ascent of blocks with sufficient gas content. It is also possible that hot, gas-rich lava fragments result from small submarine lava lakes or fountains.
A thin frozen skin of lava seals the gas cavity, and the block might then rise as a hot lava balloon. During ascent, the gas exsolves and nucleates inside the hot fragment while the blocks expand. Once at the surface the interaction between the hot blocks and the seawater produces white steam columns. At the same time, while cooling at the surface, the blocks crack slowly, lose their magmatic gas and sink. Sometimes when water enters inside the hot blocks, they blow up, violently throwing fragments several meters high.
Try our new app!: Volcanoes & Earthquakes - our new free App for Android shows the latest earthquakes and active volcanoes on a map and as list, as well as volcano news from all the world. You can filter the data shown in various ways, e.g. by magnitude or age of earthquakes, the distance from your location, the status of volcanoes and so on.
Eyjafjallajökull volcano photos: The volcano in Iceland with the unpronounceable name... but famous in 2010 when its ash clouds drifted over Europe and forced a unprecedented large-scale airspace closure for several days, stranding millions of passengers.
From Krakatau to Bali: Visit Java's famous volcanoes: Krakatau, Merapi, Bromo, Semeru, Ijen and others, crossing Java from west to east. This study and photography trip for a small exclusive group is one of our classic and best tours.
Volcano Special Tours: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
