Earthquake vs. Volcano — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on May 6, 2024
Earthquakes are sudden, violent shaking of the ground, often caused by movement along fault lines, while volcanoes are openings in Earth's crust that allow molten rock and gases to escape.

Key Differences
Earthquakes are the result of the Earth's tectonic plates moving and slipping past each other, which releases energy in the form of seismic waves, causing the ground to shake. In contrast, volcanoes form when there is a rupture in the Earth's crust, allowing magma, ash, and gases to escape from below the surface.
The location of earthquakes can be widespread, occurring along fault lines where tectonic plates meet or within the plates themselves. On the other hand, volcanoes are usually found at tectonic plate boundaries, but they can also occur in hotspots, which are locations within a plate where heat from the Earth's mantle melts the crust.
Earthquakes can happen abruptly and are usually followed by aftershocks. Volcanoes, however, may show signs of impending activity, such as seismic activity, changes in gas emissions, and ground deformation, which can provide some forewarning.
The effects of earthquakes can range from minor shaking with no damage to massive destruction of infrastructure and loss of life. Whereas, volcanoes can also cause widespread damage through eruptions, which may include lava flows, ash falls, and pyroclastic flows.
Earthquakes are primarily monitored using seismographs, which detect and record the vibrations caused by seismic waves. Volcanoes are monitored using a variety of techniques including seismographs, satellite imagery, and gas sensors to predict eruptions and study volcanic activity.

Compare with Definitions
Earthquake
Aftershocks.
Several aftershocks followed the initial earthquake.causing further anxiety.
Volcano
Can create fertile soils.
The soils around the volcano are fertile from past volcanic ash deposits.
Earthquake
Result of tectonic activity.
The major earthquake was due to the movement along a major fault line.
Volcano
Monitored by various techniques.
Scientists used satellite imagery to monitor the swelling of the volcano.
Earthquake
Potential for destruction.
The city's infrastructure suffered severe damage due to the earthquake.
Volcano
Source of magma and gases.
Gases and magma escaped through the volcano's vent during the eruption.
Earthquake
Sudden ground shaking.
The earthquake caused buildings to sway and roads to crack.
Volcano
Associated with eruptions.
The volcanic eruption forced the evacuation of thousands of residents.
Earthquake
Detected by seismographs.
Seismographs near the epicenter recorded intense seismic activity.
Volcano
Opening in Earth's crust.
The volcano erupted, spewing lava and ash into the air.
Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities.
Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.
Earthquake
A sudden movement of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity. Also called seism, temblor.
Volcano
An opening in the earth's crust from which lava, ash, and hot gases flow or are ejected during an eruption.
Earthquake
A shaking of the ground, caused by volcanic activity or movement around geologic faults.
Volcano
A similar opening on the surface of another celestial object.
Earthquake
(planetary geology) Such a quake specifically occurring on the planet Earth, as opposed to other celestial bodies.
Volcano
A usually cone-shaped mountain formed from the materials issuing from such an opening.
Earthquake
(figuratively) A sudden and intense upheaval; a severely disruptive event.
Volcano
A vent or fissure on the surface of a planet (usually in a mountainous form) with a magma chamber attached to the mantle of a planet or moon, periodically erupting forth lava and volcanic gases onto the surface.
Iceland's volcanoes are among the most active on Earth.
Earthquake
(intransitive) To undergo an earthquake.
Volcano
A kind of firework producing an upward plume of sparks.
Earthquake
A shaking, trembling, or concussion of the earth, due to subterranean causes, often accompanied by a rumbling noise. The wave of shock sometimes traverses half a hemisphere, destroying cities and many thousand lives; - called also earthdin, earthquave, and earthshock.
Volcano
To erupt; to burst forth
Earthquake
Like, or characteristic of, an earthquake; loud; startling.
The earthquake voice of victory.
Volcano
A mountain or hill, usually more or less conical in form, from which lava, cinders, steam, sulphur gases, and the like, are ejected; - often popularly called a burning mountain.
Earthquake
Shaking and vibration at the surface of the earth resulting from underground movement along a fault plane of from volcanic activity
Volcano
A fissure in the earth's crust (or in the surface of some other planet) through which molten lava and gases erupt
Earthquake
A disturbance that is extremely disruptive;
Selling the company caused an earthquake among the employees
Volcano
A mountain formed by volcanic material
Common Curiosities
How does a volcano form?
From a rupture in the Earth's crust where magma can escape to the surface.
What are the typical effects of earthquakes and volcanoes?
Earthquakes can cause structural damage and disrupt services, while volcanic eruptions can lead to lava flows, ash falls, and even climate impacts.
How often do earthquakes and volcanoes occur globally?
Earthquakes occur daily around the world, while volcanic eruptions are less frequent but can last for extended periods.
What primarily causes an earthquake?
Movement and friction along tectonic plate boundaries or faults.
What safety measures are recommended for these natural events?
For earthquakes, practice "Drop, Cover, and Hold On"; for volcanoes, heed evacuation orders and stay away from volcanic ash zones.
Can one influence the occurrence of the other?
Yes, tectonic activity related to earthquakes can sometimes trigger volcanic eruptions, especially in volcanically active regions.
Can we predict earthquakes and volcanic eruptions?
Earthquakes cannot be predicted with precision, but volcanic eruptions often show pre-eruptive activity that can be monitored.
How are earthquakes and volcanoes monitored?
Earthquakes by seismographs that record earth vibrations; volcanoes by a combination of seismographs, gas sensors, and satellite technology.
What long-term effects can these events have on the environment?
They can alter landscapes, affect climates, and create new ecosystems, especially after volcanic eruptions that enrich soils.
Are earthquakes more destructive than volcanoes?
Both can be highly destructive, but the impact depends on their magnitude, proximity to populated areas, and preparedness of the affected regions.
