Belinda was inactive until late 2001, when it erupted. The eruption produced large quantities of basalt

Basalt

Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey...

Lava

Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...

Mount Belinda has been in a persistent state of eruption since 2001. Far from slowing down, the activity throughout 2005 marks the highest levels yet. An increase in activity in the fall of 2005 has produced an active 3.5 kilometres (2.2 mi)-long lava flow, extending from the summit cone of Mount Belinda all the way down into the sea. The flow spreads northeast from the volcanic vent, and then becomes diverted due north by an arête
