Colima

Volcán de Fuego

One of Mexico’s most active volcanoes — a steep young cone where lava-dome growth, explosions and collapse can send hot volcanic material rapidly down the flanks.

Mexico’s restless fire volcano

The active cone is only half of the Colima skyline

Volcán de Colima — also known as Volcán de Fuego — forms the younger, historically active part of the Colima Volcanic Complex in western Mexico.

Immediately to its north stands the older Nevado de Colima. Together the neighbouring edifices create one of Mexico’s most recognisable volcanic landscapes, but it is the younger Fuego cone that has produced the complex’s recent historical eruptions.

Colima is especially well known for cycles of viscous lava extrusion, lava-dome growth, explosions and gravitational collapse. When hot unstable material fails, pyroclastic density currents can descend the steep radial valleys at high speed.

Activity and behaviour

Lava growth, explosions and collapse can happen in the same eruptive cycle

Evergreen profile
How Colima behaves

Colima’s modern eruptive behaviour often alternates between extrusion of viscous lava, growth of summit domes or lava lobes, explosive ash emissions and collapse. This makes the upper cone dynamic even when activity is not dominated by large explosions.

Dome instability

A growing lava dome can become its own hazard

Viscous lava does not always flow cleanly away from the vent. At Colima it can pile up into unstable domes and thick lobes. Gravity, explosions or continued extrusion can destabilise them, sending incandescent blocks and hot ash down the flanks.

Dome growthViscous lava accumulates near the summit.
OversteepeningContinued extrusion can make hot lava increasingly unstable.
CollapseBreaking lava fragments into blocks, ash and hot gas.
Valley confinementTopography can funnel pyroclastic material rapidly downslope.
Colima Volcanic Complex

Nevado and Fuego share the skyline, but not the same eruptive role

The older Nevado de Colima stands immediately north of the younger active cone. Its broad, eroded form contrasts with the steep profile of Volcán de Fuego.

This neighbouring pair records the migration and rebuilding of volcanism through time. The name “Colima” can therefore be confusing: the historically active volcano is Volcán de Fuego, while Nevado de Colima is the older edifice beside it.

How Colima works

The summit can repeatedly build itself up and tear itself apart

When relatively viscous magma reaches the surface it may extrude slowly, building a dome or thick lava lobe. Continued magma supply can push this material outward until parts of it become unstable.

Collapse exposes hot interior lava and produces avalanches of blocks and ash. Mixing and fragmentation can transform these into fast pyroclastic density currents, while renewed extrusion begins the cycle again.

Monitoring

Watching a summit that can change shape during an eruption

Colima requires monitoring that can follow both processes inside the volcano and physical changes at the summit. Seismicity is interpreted alongside visual observations, deformation, gas measurements and remote sensing.

SeismicityEarthquakes and tremor reveal fracturing, explosions and magma movement.
Visual surveillanceCameras track ash emissions, incandescent material and dome changes.
Ground deformationGeodetic measurements look for pressure-related movement.
Volcanic gasGas output helps reveal changes in magma supply and degassing.
Thermal observationsHeat can identify active lava and newly exposed dome material.
Deposit mappingFieldwork reconstructs pyroclastic-flow and lahar pathways.

Volcán de Colima eruption timeline

16th century

Historical eruptions enter the written record

Accounts establish a centuries-long record of repeated explosive and effusive activity at Volcán de Fuego.

Major eruption1818

Powerful explosive eruption

A major 19th-century event produced widespread ash and represents one of Colima’s important historical eruptions.

Major eruption1913

Large explosive eruption reshapes the summit

A powerful eruption generated substantial ashfall and pyroclastic activity and left major changes around the summit crater.

1961–62

Renewed lava extrusion

Effusive activity marked the return of lava growth following decades of relative quiet.

1998–2011

Repeated dome growth and explosive activity

Long-lived episodes of extrusion, explosions and dome collapse demonstrated the characteristic modern behaviour of the volcano.

Intense activity2015

Major dome collapse and pyroclastic flows

Large collapses generated powerful pyroclastic density currents down the flanks and prompted evacuations around the volcano.

2016–17

Explosions, lava extrusion and renewed pyroclastic activity

Another active phase produced frequent ash plumes, incandescent material and episodes of pyroclastic flow generation.

Hazards

The hazards that matter most at Colima

Pyroclastic density currents

Hot blocks, ash and gas can descend valleys at high speed.

Ballistic ejecta

Explosions can throw blocks and bombs around the summit and upper flanks.

Ashfall

Ash can affect communities, agriculture, roads and aviation downwind.

Lava flows

Extruded lava can move down the upper cone and feed unstable lobes.

Lahars

Rain can remobilise volcanic deposits into destructive valley-confined flows.

Debris avalanches

Large structural failures are part of the complex’s longer-term geological history.

Myths versus reality

Colima is not simply an exploding cone

Myth“The biggest danger only comes from major explosions.”

Gravitational collapse of a growing lava dome can generate destructive pyroclastic currents without a huge vertical eruption column.

Myth“Nevado de Colima is the active volcano.”

The historically active younger cone is Volcán de Fuego, immediately south of the older Nevado edifice.

Myth“Lava domes grow too slowly to be dangerous.”

Their growth may be slow, but collapse can suddenly accelerate hot material down steep valleys.

Volcoholics insight

At Colima, destruction can be part of the volcano’s growth

Volcán de Fuego repeatedly builds lava around its summit only to lose parts of it again through collapse and explosion. That cycle is what makes Colima so compelling — construction and destruction are not opposing phases here, but two parts of the same eruptive process.

Questions answered

Volcán de Colima explained

Is Volcán de Colima the same as Volcán de Fuego?

Yes. The historically active cone commonly called Volcán de Colima is also known as Volcán de Fuego.

Is Nevado de Colima the same volcano?

Nevado de Colima is the older neighbouring edifice within the wider Colima Volcanic Complex.

Why are lava domes dangerous at Colima?

Viscous lava can accumulate into unstable summit domes and lobes. Their collapse can generate hot block-and-ash flows and pyroclastic density currents.

What happened at Colima in 2015?

Major lava-dome collapses generated powerful pyroclastic density currents down the volcano’s flanks and led to evacuations.
