Live Volcano Eruption Tracker – Active Volcanoes Worldwide

Monitor volcanic activity around the world with the Orbis Weather Live Volcano Eruption Tracker. The interactive global map brings together current volcanic-event information and recent earthquake activity, providing an easy way to explore where significant geological activity is occurring around the planet.

The tracker combines volcanic-event information from NASA’s Earth Observatory Natural Event Tracker with recent earthquake data from the U.S. Geological Survey.

Visitors can explore active volcanic events, recent eruptions and nearby earthquakes while filtering seismic activity by magnitude and time period.

From Indonesia and Japan to Iceland, Italy, Hawaii, Alaska and the Pacific Ring of Fire, the map provides a global view of our constantly changing planet.

🌋 How the Live Volcano Eruption Tracker Works

The Orbis Weather volcano tracker combines two different types of geological information on one interactive map.

Volcanic events are displayed using information from NASA EONET, while recent earthquake information comes from the U.S. Geological Survey Earthquake Hazards Program.

Displaying volcanoes and earthquakes together provides useful context because seismic activity frequently occurs around active volcanic systems.

However, an earthquake near a volcano does not automatically mean an eruption is imminent.

Scientists use many different types of observations when determining whether a volcano is becoming more active.

🌎 What Does “Ongoing Volcanic Event” Mean on the Map?

The term “active” can have different meanings depending on the context.

On the Orbis Weather tracker, an ongoing volcanic event represents an event that NASA EONET currently lists without a recorded closure date. This does not necessarily mean the volcano is continuously erupting or currently at an elevated official alert level.

That does not necessarily mean a volcano is continuously erupting at this exact moment.

Some volcanic events remain open while activity continues to be monitored.

For authoritative information about the current status of an individual volcano, always consult the responsible national volcano observatory or the Smithsonian Institution’s Global Volcanism Program.

🔥 Why Do Volcanoes Erupt?

Volcanoes form when molten rock, gases and other material from beneath Earth’s surface move upward through the crust.

This molten material is called magma while it remains underground.

When magma reaches the surface, it is called lava.

As magma rises, changes in pressure can allow dissolved gases to expand.

Depending on the magma’s composition, gas content and other conditions, an eruption may involve relatively gentle lava flows or powerful explosions capable of sending ash high into the atmosphere.

Every volcano behaves differently, which is why scientists continuously monitor active volcanic systems.

🌋 Different Types of Volcanic Eruptions

Not all eruptions look like dramatic explosions.

Some volcanoes produce relatively fluid lava that can travel significant distances across the ground.

Other eruptions involve thick, gas-rich magma capable of producing violent explosions.

Explosive eruptions can send volcanic ash and rock fragments high into the atmosphere.

Some eruptions produce pyroclastic flows — extremely hot, fast-moving mixtures of gas, ash and volcanic material that travel down the sides of a volcano.

Volcanoes covered by snow or ice can create additional hazards when eruptions rapidly melt frozen water.

☁️ What Is Volcanic Ash?

Volcanic ash is not the same as the soft ash produced by burning wood.

It consists of tiny fragments of volcanic rock, minerals and glass created during explosive eruptions.

Fine volcanic ash can travel hundreds or even thousands of miles depending on eruption height and atmospheric winds.

Ashfall can reduce visibility, contaminate water supplies, damage machinery and affect human health.

Heavy ash accumulation can also add substantial weight to roofs and other structures.

✈️ Why Volcanic Ash Is Dangerous for Aircraft

Volcanic ash presents a significant aviation hazard.

Ash particles can damage aircraft surfaces and instruments and can cause serious problems if ingested into jet engines.

For this reason, major eruptions can result in flight diversions, airport closures and changes to international air routes.

Volcanic Ash Advisory Centers monitor significant ash clouds and provide specialized information to the aviation community.

Travelers should check directly with airlines and aviation authorities when volcanic activity is affecting their route.

🌋 What Are Pyroclastic Flows?

Pyroclastic flows are among the most dangerous volcanic hazards.

They are rapidly moving mixtures of extremely hot gas, ash and volcanic debris that can travel down the slopes and valleys surrounding an erupting volcano.

These flows can move at very high speeds and reach temperatures capable of destroying structures and vegetation.

People should never enter official exclusion zones around volcanoes experiencing explosive activity.

Local volcano observatories and emergency authorities determine hazard zones based on the behavior and history of each volcanic system.

💧 What Is a Lahar?

A lahar is a volcanic mudflow consisting of water mixed with ash, rock and other volcanic debris.

Lahars can develop during or after an eruption.

Heavy rainfall can remobilize volcanic ash and debris long after the main eruptive activity has ended.

Melting snow and ice can also generate dangerous volcanic mudflows.

Lahars often follow river valleys and drainage channels, allowing them to travel significant distances from a volcano.

This means communities located far downstream can sometimes remain at risk even when they are not close to the crater.

🌊 Can Volcanoes Cause Tsunamis?

Some volcanic events can generate tsunamis.

Large volcanic explosions, underwater eruptions, collapsing volcanic slopes and caldera collapse can displace large amounts of water.

However, most volcanic eruptions do not produce significant tsunamis.

If authorities issue a tsunami warning following a volcanic event, people in threatened coastal areas should immediately follow official evacuation instructions.

The volcano tracker itself should never be used to determine whether a tsunami threat exists.

🌎 The Pacific Ring of Fire

Many of Earth’s most active volcanoes are located around the Pacific Ocean in a broad region commonly called the Pacific Ring of Fire.

This tectonically active zone includes Indonesia, the Philippines, Japan, Papua New Guinea, New Zealand, Alaska, the western Americas and numerous Pacific islands.

The region contains many places where tectonic plates converge and one plate is forced beneath another in a process known as subduction.

Subduction zones can generate both powerful earthquakes and volcanic activity.

This is why the Orbis Weather map often shows clusters of earthquakes and volcanic events around the Pacific.

🇮🇩 Why Indonesia Has So Many Active Volcanoes

Indonesia is one of the world’s most volcanically active countries.

The archipelago sits along several major tectonic boundaries where plates interact.

Volcanoes including Merapi, Semeru, Ibu, Dukono, Marapi, Anak Krakatau and Lewotobi Laki-laki are among the country’s closely monitored volcanic systems.

Because Indonesia has such a large population living near active volcanoes, eruptions can create significant hazards involving ashfall, pyroclastic flows, lahars and aviation disruption.

Orbis Weather also maintains a dedicated Indonesia Volcano Tracker for readers following activity across the country.

🇯🇵 Volcanoes in Japan

Japan is another highly active volcanic region associated with the Pacific Ring of Fire.

The country’s complex tectonic setting produces both frequent earthquakes and numerous active volcanoes.

The Japan Meteorological Agency monitors volcanic activity and issues warnings and volcanic alert information when necessary.

Residents and travelers near active Japanese volcanoes should always follow official JMA guidance and local restrictions.

🇮🇸 Iceland’s Volcanoes

Iceland sits along the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are moving apart.

The island is also influenced by unusually active mantle processes beneath the region.

Together, these geological conditions make Iceland one of the world’s most volcanically active locations.

Icelandic eruptions can range from relatively localized lava flows to events capable of producing significant ash and aviation disruption.

The Icelandic Meteorological Office is an important authoritative source for current volcanic and seismic activity in Iceland.

🇺🇸 Volcanoes in the United States

The United States contains numerous active and potentially active volcanoes.

Alaska has a particularly large concentration of volcanoes associated with the Aleutian volcanic arc.

Hawaii contains some of the world’s best-known active volcanoes, including Kīlauea and Mauna Loa.

The Cascade Range of the Pacific Northwest includes Mount St. Helens, Mount Rainier, Mount Hood and other potentially active volcanoes.

The U.S. Geological Survey Volcano Hazards Program and its regional volcano observatories monitor these systems for signs of changing activity.

🌋 Volcanoes and Earthquakes

Earthquakes frequently occur near volcanoes because moving magma and volcanic fluids can fracture surrounding rock.

Scientists carefully monitor changes in earthquake frequency, location and type beneath active volcanic systems.

But earthquake activity by itself cannot tell us whether an eruption is about to occur.

Volcano observatories combine seismic observations with ground deformation, volcanic gas measurements, satellite imagery, thermal observations and direct field measurements.

A cluster of earthquakes near a volcano should therefore never automatically be interpreted as evidence that an eruption is imminent.

📈 What Is Volcanic Unrest?

Volcanic unrest describes changes that indicate a volcanic system is behaving differently from its normal background activity.

Possible signs can include increased earthquakes, changes in volcanic gas emissions, ground deformation or changes in heat output.

Unrest does not always lead to an eruption.

Some volcanoes experience periods of elevated activity that eventually return to background levels without erupting.

This uncertainty is one reason professional volcano monitoring requires multiple types of scientific observations.

🚦 Understanding Volcano Alert Levels

Many countries use volcano alert levels to communicate changes in volcanic activity and potential hazards.

However, there is no single universal alert-level system used everywhere in the world.

Different national agencies use different scales, terminology and criteria.

A color or number used for one country’s volcano should therefore not automatically be compared with the same color or number used elsewhere.

Always consult the responsible volcano observatory for the current official alert level and its meaning.

🛰️ How Satellites Monitor Volcanoes

Satellites have become extremely valuable for volcano monitoring.

They can detect thermal activity, observe ash clouds, identify sulfur dioxide emissions and measure changes in Earth’s surface.

Satellite observations are particularly useful for remote volcanoes where permanent ground-monitoring equipment may be limited.

However, satellites are only one part of modern volcano monitoring.

Ground-based seismic instruments, GPS stations, gas sensors and direct observations remain extremely important.

📍 Is There an Active Volcano Near Me?

The Orbis Weather map allows visitors to explore volcanic events around the world and examine recent earthquakes near active volcanic regions.

Zoom into your country or region to see currently displayed events.

Remember that absence from an interactive event map does not prove that a volcano is inactive or safe.

Likewise, a volcano displayed as an ongoing event does not necessarily mean a dangerous eruption is occurring at that exact moment.

Always consult your country’s official geological or volcano-monitoring agency for local hazard information.

🔎 Can Scientists Predict Volcanic Eruptions?

Scientists can sometimes recognize signs that make an eruption more likely, but predicting the exact time and size of an eruption remains extremely difficult.

Some volcanoes provide clear warning signs before erupting.

Others can change quickly or behave in unexpected ways.

Modern monitoring allows scientists to identify unrest and estimate potential hazards much more effectively than in the past, but forecasts still contain uncertainty.

Claims that an eruption can always be predicted to an exact date and time should be treated cautiously.

🛰️ Where Does Orbis Weather Get Volcano Data?

The Orbis Weather Live Volcano Eruption Tracker uses NASA EONET to display volcanic events and USGS data for recent earthquake activity.

For authoritative eruption histories and detailed information about individual volcanoes, Orbis Weather recommends consulting the Smithsonian Institution Global Volcanism Program.

For U.S. volcanoes, the USGS Volcano Hazards Program and its regional observatories provide official monitoring information.

Outside the United States, readers should follow the responsible national volcano observatory or geological agency.

Orbis Weather organizes these resources into an accessible global tracker but does not independently determine whether a volcano is erupting or assign official volcanic alert levels.

🌎 Monitor Global Volcanic Activity

Earth’s volcanoes are constantly changing.

Some remain quiet for decades or centuries, while others experience frequent eruptions and extended periods of unrest.

The Orbis Weather Live Volcano Eruption Tracker provides a convenient way to explore active volcanoes, recent eruptions and nearby earthquake activity around the world.

Return regularly to monitor global volcanic events and explore related Orbis Weather resources including the Real-Time Earthquake Map, Indonesia Volcano Tracker, Volcano Live Cam and Weekly Earth Watch: Volcanoes, Earthquakes & Natural Hazards.

Important Volcano Safety Disclaimer

The Orbis Weather Live Volcano Eruption Tracker is provided for general information, education and situational awareness.

Volcanic conditions can change rapidly, and event information displayed on global datasets may be delayed, incomplete or interpreted differently from official national alert systems.

An event shown as “ongoing” does not necessarily mean a volcano is actively erupting at that exact moment.

Never use this tracker to make evacuation, exclusion-zone, aviation or other life-safety decisions.

Always follow warnings, exclusion zones, evacuation instructions and emergency information issued by the responsible volcano observatory, geological agency and local authorities.
