What if you could watch a brand new island rise out of the ocean? Not over millions of years, but in front of people in real time.
Watch the volcanic island Surtsey emerge from the ocean in 1963 and discover how life colonizes new land in real time.
Key Takeaways
- Surtsey is a rare example of a new island forming in real time.
- Volcanic activity can create new land rapidly, starting underwater.
- Life colonizes new volcanic islands gradually, starting with simple organisms and plants.
- Natural protection and minimal human interference allow scientific study of ecological succession.
- Ocean erosion continuously reshapes volcanic islands, influencing their survival and ecosystem development.
What the video covers
- Surtsey is a volcanic island that emerged off Iceland's southern coast starting November 14, 1963.
- The eruption began underwater over 100 meters below sea level, causing violent explosions when magma met cold seawater.
- Within about a day, new land appeared above the ocean, and eruptions continued for over three years until 1967.
- By the end of the eruption, Surtsey covered more than 2.5 square kilometers.
- The island was protected from human interference to study how life colonizes new land.
- Initial colonization involved seeds, tiny organisms, and eventually birds that helped enrich the soil.
- Surtsey developed its own ecosystem despite constant erosion by the Atlantic Ocean.
- Hard lava flows helped protect the island from complete destruction unlike other volcanic islands from the same eruption.
- The island continues to change with shifting cliffs, coastline, and species arrivals and disappearances.
- Surtsey serves as a natural experiment on geology, oceanic reshaping, and biological colonization.

This is Surtsey, a volcanic island off the southern coast of Iceland. On November 14th, 1963, sailors noticed something strange in the North Atlantic. A dark column of smoke and ash was rising from the sea.
Speaker A
But the eruption had actually begun underwater, more than 100 m below the surface. Magma was forcing its way upward. When it met cold seawater, violent explosions blasted ash, steam, and volcanic rock into the air. And within about a day, new land
Speaker A
appeared above the ocean. An island was being born. But Surtsey did not stop growing. For more than 3 years, eruptions continued. Ash built volcanic cones. Lava poured across the new surface. By the time the eruption ended
Speaker A
in 1967, Surtsey covered more than 2 and 1/2 square kilometers. Scientists quickly realized they were seeing something incredibly rare, a completely new piece of land with almost no human influence. So, the island was protected while it was still
Speaker A
young. Tourists were kept away, and scientists began watching one extraordinary question. How does life colonize a brand new island?
Speaker A
At first, there was almost nothing. Bare lava, black ash, wind, ocean spray. Then, life started arriving. Seeds washed ashore on ocean currents. Tiny organisms arrived with wind and water. The first higher plant was found in 1965.
Speaker A
Birds landed on the island. Later, some began nesting there. Their droppings added nutrients to the young volcanic soil, helping more plants grow. Slowly, a barren volcanic island began developing its own ecosystem. But while life was moving in, the
Speaker A
Atlantic Ocean was taking land away. Powerful waves constantly erode Surtsey. Other small volcanic islands created during the same eruption were completely destroyed by the sea. Surtsey survived partly because hard lava flows protected its softer volcanic material.
Speaker A
Even today, the island continues to change. Its cliffs retreat. Its coastline moves. New species arrive.
Speaker A
Others disappear. And scientists keep watching. Surtsey is not simply an island created by a volcano. It is a natural experiment showing how geology creates new land, how the ocean reshapes it, and how life slowly finds a way to move in.
