August 2026: Fuego Erupts Again
The reason people are searching for Guatemalan volcanoes right now is Volcán de Fuego. It began a strong eruptive phase around 8:30 a.m. local time on Monday, August 3, 2026, and escalated into a full paroxysm that night — lava fountains 200 to 300 m above the crater and pyroclastic density currents racing 5 to 7 km down six ravines. SE-CONRED declared an Institutional Orange Alert, closed National Route 14, and evacuated about 1,700 people from at least 18 communities. INSIVUMEH declared the eruption over on Wednesday, August 6, after roughly 50 hours — but warned that rain from an incoming tropical wave could turn the fresh debris into lahars, the mudflows that have historically caused Fuego's worst downstream damage.
None of this is unusual for Guatemala. It is simply the most volcanically active country in Central America, and Fuego is the busiest volcano on it. To understand why, you have to look at the fault line the whole country sits on.
The Central American Volcanic Arc
Every active volcano in Guatemala lines up along a single feature: a roughly 1,500 km chain of volcanoes running from the Mexican border down through El Salvador, Nicaragua, and Costa Rica. It exists because the Cocos Plate is sliding beneath the Caribbean Plateat the Middle America Trench, off Guatemala's Pacific coast. As the descending slab heats up, it releases water that melts the rock above it; that melt rises to build the arc. It is the same subduction engine that powers the wider Pacific Ring of Fire.
That geometry gives Guatemala mostly stratovolcanoes — the steep, layered, explosive cones that built Fuego, Acatenango, Agua, and Atitlán, often in neat lines and clustered pairs. Fuego and Acatenango are literally twins, joined at a saddle, which is why hikers watch one erupt from the flank of the other.
Guatemala's Major Volcanoes, With Eruption Data
These are the highest and most active volcanoes in our Guatemalan dataset. "Recorded eruptions" counts confirmed eruptive events in the Smithsonian catalog — a good proxy for how restless each volcano has been.
| Volcano | Elevation | Type | Last Eruption | Eruptions |
|---|---|---|---|---|
| TajumulcoThe highest peak in all of Central America. | 4,203 m | Stratovolcano | — | 2 |
| AcatenangoThe overnight hike here is the classic way to watch Fuego erupt. | 3,976 m | Stratovolcano | 1972 CE | 8 |
| FuegoCentral America's most active volcano. Paroxysm Aug 3–5, 2026. | 3,799 m | Stratovolcano | 2026 CE | 79 |
| AguaNo confirmed Holocene eruptions. Towers over Antigua Guatemala. | 3,760 m | Stratovolcano | — | 0 |
| Santa MaríaIts 1902 VEI 6 killed 5,000+; the Santiaguito dome has grown since 1922. | 3,745 m | Stratovolcano | 2025 CE | 3 |
| AtitlánOverlooks Lake Atitlán, a caldera lake ringed by volcanoes. | 3,535 m | Stratovolcano | 1853 CE | 15 |
| AlmolongaCerro Quemado dome complex above Quetzaltenango. | 3,173 m | Stratovolcano | 1818 CE | 3 |
| PacayaThe most-visited guided volcano hike, near Guatemala City. | 2,569 m | Complex | 2021 CE | 36 |
Elevations from our Smithsonian GVP records; eruption-event counts from the GVP eruption catalog. Santa María's low record count reflects how the GVP catalogs the century-long Santiaguito dome episode as a single ongoing event.
Fuego: The Busiest Volcano in Central America
Our database records 79 eruptions at Fuego since 1524 — more than any other Guatemalan volcano, and one of the highest tallies in the whole catalog. Since January 2002 it has been in a single continuous eruptive phase, producing 6 to 12 Strombolian explosions an hour between larger paroxysms like the one in August 2026. It is worth being precise about the danger here: the eruptions themselves are usually modest (the overall phase is graded VEI 3), but the deadliest events come from pyroclastic flows channeled into populated ravines — exactly what killed at least 190 people on June 3, 2018. Read the full story on our Volcán de Fuego page.
Santa María and Santiaguito: A VEI 6 and Its Century-Old Scar
On October 24, 1902, Santa María produced one of the largest eruptions of the entire 20th century — a VEI 6 Plinian blast that lasted about 20 hours and killed an estimated 5,000 to 8,700 people. It is one of only two VEI 5+ eruptions in our Guatemalan records. Two decades later, in 1922, a new lava dome called Santiaguito began growing inside the 1902 crater, and it has been erupting almost continuously ever since — slow dome growth, block-and-ash flows, and occasional collapses. It is one of the best places on Earth to watch a lava dome behave in real time, which is why volcanologists have monitored Santiaguito for a century.
Hiking Guatemala's Volcanoes
Guatemala is one of the few countries where you can safely hike up one active volcano to watch another one erupt. Here is the honest rundown:
- Acatenango (3,976 m) — the headline trek. A hard two-day overnight climb from La Soledad that camps on a ridge facing Fuego, so you spend the night watching lava fountains a few kilometers away. Real altitude and cold; not a casual day out.
- Pacaya (2,569 m) — the easy one. A guided half-day hike from near Antigua or Guatemala City, often close enough to feel heat from recent lava. The most popular volcano tour in the country.
- Tajumulco (4,203 m) — the highest point in Central America. Non-technical but a genuine high-altitude slog, usually done as an overnight from Quetzaltenango.
- Agua (3,760 m) — a steep day hike straight up from Antigua, with a history of robberies on the trail; go with a guided group.
- Fuego — off-limits. Its active cone is restricted to INSIVUMEH monitoring staff, and during a paroxysm like August 2026 the whole area closes.
Planning a volcano trip to Guatemala?
Acatenango overnight tours from Antigua run roughly $35–80 for budget operators and $90–150 for mid-range trips with better gear and smaller groups; Pacaya half-day hikes are usually $25–60. Always check the current INSIVUMEH and CONRED bulletins before booking — after a Fuego paroxysm, Acatenango access and nearby roads can close overnight. Compare with neighboring regions in our Mexico and Costa Rica volcano guides, and read our volcano hiking safety guide first.
Frequently Asked Questions
How many volcanoes does Guatemala have?
Our database holds 23 Guatemalan volcanoes with 148 recorded eruptions between them; the Smithsonian counts around 37 volcanic centers nationwide and roughly 20–21 active during the Holocene. They line up along the Central American Volcanic Arc, a chain built where the Cocos Plate dives beneath the Caribbean Plate. Three of them — Fuego, Pacaya, and the Santiaguito dome on Santa María — are erupting more or less continuously.
Is Fuego volcano erupting right now in 2026?
Fuego has erupted continuously since 2002, and its most recent major paroxysm ran August 3–5, 2026 — sending pyroclastic flows up to 7 km, evacuating about 1,700 people, and closing National Route 14 under a national Orange Alert. Guatemala's INSIVUMEH declared that eruption over on August 6, 2026, and evacuees returned home, though authorities warned rain could still trigger lahars.
What is the tallest volcano in Guatemala?
Tajumulco, at 4,203 m in our database, is the tallest volcano in Guatemala — and the highest peak in all of Central America. It is a dormant stratovolcano in the western highlands near the Mexican border, and it is a non-technical (if strenuous) high-altitude hike rather than an active eruption risk.
Which Guatemalan volcanoes can you hike?
Acatenango (3,976 m) is the headline trek — a two-day overnight climb that puts you across a saddle from erupting Fuego. Pacaya (2,569 m) is a short, popular half-day hike near Guatemala City where you can often see glowing lava up close. Tajumulco (4,203 m) is the highest but least-visited. You cannot climb Fuego's active cone — it is restricted to INSIVUMEH monitoring staff.
What was the deadliest volcanic eruption in Guatemala?
The 1902 Plinian eruption of Santa María was one of the largest of the 20th century — a VEI 6 that killed an estimated 5,000 to 8,700 people. The 2018 Fuego disaster, though only VEI 3, killed at least 190 and left over 260 missing when pyroclastic flows buried villages in the Escuintla department. In our database, only 8 of Guatemala's 148 recorded eruptions reached VEI 4 or higher.
