Imagine standing near a volcano as it erupts. The ground shakes, and rivers of hot lava flow. But sometimes, something else amazing happens. The wind can create delicate, hair-like strands of glass.
These aren't just any strands. They are known as Pele's Hair, named after the Hawaiian volcano goddess. This natural phenomenon turns fiery explosions into delicate, beautiful objects that tell a story of incredible power.
What is Pele's Hair?
Pele's Hair is a type of volcanic glass. It forms when lava is thrown into the air during an eruption. As the lava flies, strong winds can stretch it out into thin threads. These threads cool quickly in the air, becoming brittle strands of glass.
The strands are usually golden-brown or reddish-brown in color. This is because of tiny iron particles in the lava. They look a lot like human hair, which is why they got their name. The goddess Pele is said to be the creator of the Hawaiian Islands, and her fiery temper is believed to cause the eruptions.
The Science
Behind the Strands
The formation of Pele's Hair is a fascinating process. It requires a specific set of conditions. First, you need an eruption that throws molten lava high into the air. This is often seen in lava fountains or explosive eruptions.
As the lava droplets are ejected, they are caught by the wind. The wind pulls and stretches the liquid rock. If the wind is strong enough and the lava is thin enough, it can stretch into very long, thin strands. These strands cool very fast. This rapid cooling prevents them from forming larger, solid rocks.
This type of volcanic glass is also known as Pele's strands. It's a type of basaltic glass. The specific type of lava, its temperature, and the force of the wind all play a role in how much Pele's Hair is created.
Pele's Tears: A Companion Phenomenon
Sometimes, Pele's Hair is found alongside another volcanic creation called Pele's Tears. These are small, tear-shaped droplets of lava. They form when lava is thrown into the air and cools into rounded beads.
Like Pele's Hair, Pele's Tears are named after the goddess. They represent the tears she cries. While Pele's Hair is long and stringy, Pele's Tears are small and solid. Both are beautiful reminders of the volcano's power.
Often, you'll find Pele's Tears with a thin strand of Pele's Hair attached. This happens when a droplet cools and solidifies while still being stretched by the wind. It's a beautiful combination of two different volcanic wonders.
Where Can You Find Pele's Hair?
Pele's Hair is most commonly found in areas with active volcanism. Hawaii is the most famous location, especially on the Big Island. Here, Kīlauea volcano is a frequent source of these glassy strands.
