Scattered across Jeju Island like ancient sentinels, over 360 oreums (오름)—volcanic cones—rise from the landscape, creating one of the world's most distinctive and enchanting volcanic terrains. These graceful hills, formed by past eruptions, possess a seductive charm that has captivated visitors for centuries. More than mere geological features, oreums are sacred spaces, hiking destinations, and windows into the island's fiery past.

The word "oreum" comes from the Jeju dialect, meaning "mountain" or "hill," but these formations are far more than simple elevations. Each oreum tells a unique story of volcanic activity, ecological adaptation, and cultural significance. Together, they create a landscape that seems almost otherworldly—a place where the earth's creative forces are visible in every gentle slope and crater rim.

Understanding Oreums: Volcanic Architecture

Formation and Geological Significance

Oreums represent a specific type of volcanic formation known as monogenetic cones—volcanic features formed by a single eruptive episode. Unlike Hallasan, which built up over millions of years, each oreum was created during a relatively brief period of volcanic activity.

Formation Process:

Initial Eruption: Magma breaks through the earth's surface at a weak point
Cone Building: Repeated small explosions build up a cone of volcanic material
Crater Formation: The final stages create a distinctive crater at the summit
Cooling and Stabilization: The cone cools and becomes dormant

Geological Diversity: Jeju's oreums display remarkable variety:

Scoria Cones: Built from loose volcanic fragments, creating gentle slopes
Tuff Rings: Formed by explosive interactions with groundwater
Spatter Cones: Created by fluid lava fountains
Complex Cones: Combinations of different eruptive styles

The Oreum Landscape

The distribution of oreums across Jeju creates a unique landscape pattern:

Spatial Distribution: Oreums are not randomly scattered but follow geological patterns:

Rift Zones: Many oreums align along volcanic rift zones
Elevation Patterns: Different types occur at different elevations
Clustering: Some areas have dense concentrations of oreums
Isolation: Others stand alone as solitary landmarks

Size Variations: Oreums range dramatically in size:

Small Cones: Some rise only 20-30 meters above surrounding terrain
Major Oreums: The largest exceed 300 meters in height
Crater Dimensions: Crater sizes vary from small depressions to large amphitheaters
Base Diameters: Range from a few hundred meters to several kilometers
