Shield volcanoes on Venus
- On Venus, where there are no tectonic plates or seawater, volcanoes are mostly of the shield type. Nevertheless, the morphology of volcanoes on Venus is different: on Earth, shield volcanoes can be a few tens of kilometres wide and up to 10 km (6.2 mi) high in the case of Mauna Kea , measured from the sea floor.
FAQ
Those who are looking for an answer to the question «Volcanoes on venus are shield volcanoes?» often ask the following questions:
♻️ Are there any large shield volcanoes on venus?
- VE=~25 The Hawaiian Islands are often used as examples of large shield volcanoes on Earth. These volcanoes are on the order of 120 kilometers wide at the base and about 8 kilometers in height. They would be among the tallest volcanoes on Venus; however, they would not be competitive in width.
- Does venus have volcanoes?
- What are some examples of large shield volcanoes?
- Are there volcanoes on venus?
♻️ What is the difference between shield volcanoes on venus and earth?
- Shield volcanoes: Venus vs. Earth: This graphic compares the geometry of a large shield volcano from Venus with a large shield volcano from Earth. Shield volcanoes on Venus are usually very broad at the base and have gentler slopes than the shield volcanoes found on Earth.
♻️ Does venus has volcanoes?
- Earth is one of several worlds in our solar system known to have active volcanoes. Now, a new study from Universities Space Research Association (USRA) confirms that – as has been conjectured before – cloud-covered Venus appears to be volcanically active as well. It’s been known since the early 1990s that Venus has many volcanic features.

How many volcanoes are on venus?746
- On Venus, these volcanoes can cover hundreds of kilometres in area, but they are relatively flat, with an average height of 1.5 km (0.93 mi). Large volcanoes cause the Venusian lithosphere to flex downward because of their enormous vertical loads, producing flexural moats and/or ring fractures around the edifices.
- Even though there are over 1,600 major volcanoes on Venus, none are known to be erupting at present and most are probably long extinct. However, radar sounding by the Magellan probe revealed evidence for comparatively recent volcanic activity at Venus 's highest volcano Maat Mons , in the form of ash flows near the summit and on the northern flank.
Venus' coronae are generated by plumes of molten rock rising from the mantle up through the crust, a process similar to the one that formed the Hawaiian Islands here on Earth. (Most of our planet's volcanism, however, occurs along the boundaries of tectonic plates, which modern Venus doesn't seem to possess.)
What type of volcanoes are on venus?- Venus has shield volcanoes, widespread lava flows and some unusual volcanoes called pancake domes and "tick-like" structures which are not present on Earth. Pancake dome volcanoes are up to 15 km (9.3 mi) in diameter and less than 1 km (0.62 mi) in height and are 100 times the size those formed on Earth.
- More volcanoes are known on Venus than Earth, but when Venusian volcanoes last erupted is not directly known. Evidence bolstering very recent volcanism on Venus has recently been uncovered, though, right here on Earth.
- Discovery of a Volcanic Landscape. Venus is the closest planet to Earth. However, the surface of Venus is obscured by several layers of thick cloud cover. These clouds are so thick and so persistent that optical telescope observations from Earth are unable to produce clear images of the planet's surface features.
- The surface of Venus is dominated by volcanic features and has more volcanoes than any other planet in the Solar System.
- Venus has more volcanoes than any other planet in the solar system. Over 1600 major volcanoes or volcanic features are known (see map), and there are many, many more smaller volcanoes. (No one has yet counted them all, but the total number may be over 100,000 or even over 1,000,000).
- Among the volcanoes of Venus are Sif Mons (shown here with a lava plain) and Gula Mons on Western Eistla Regio, Rhea Mons and Theia Mons on Beta Regio, Eve on Alpha Regio, Sacajawea and Colette on Ishtar Terra, and Sapas Mons, Maat Mons, and Ozza Mons on Atla Regio.
- Volcanic activity is the dominant process for shaping the landscape of Venus, with over 90% of the planet's surface being covered by lava flows and shield volcanoes. The shield volcanoes and lava flows on Venus are very large in size when compared to similar features on Earth. Author: Hobart M. King, Ph.D.
- Earth is one of several worlds in our solar system known to have active volcanoes. Now, a new study from Universities Space Research Association (USRA) confirms that – as has been conjectured before – cloud-covered Venus appears to be volcanically active as well. It’s been known since the early 1990s that Venus has many volcanic features.
The oceanic crust covers 60% of Earth's surface. It is host to more than 100,000 hotspot volcanoes that have formed in less than 100m years. Conversely, Venus' entire surface has produced only 70,000 individual volcanoes over a period of some 700m years (give or take 300m) – roughly the age of its outer crust.
What are the different types of volcanoes on venus?- Types of volcanoes. Venus has shield volcanoes, widespread lava flows and some unusual volcanoes called pancake domes and "tick-like" structures which are not present on Earth.
- These video stills show the volcanic peak Idunn Mons (at 46 degrees south latitude, 214.5 degrees east longitude) in the Imdr Regio area of Venus. Image credit: NASA/JPL-Caltech/ESA PASADENA, Calif. -- For the first time, scientists have detected clear signs of recent lava flows on the surface of Venus.
- The evidence for currently active volcanoes on Venus includes surface features resembling those produced in earthly volcanism, fluctuating levels of sulfur dioxide in Venus's atmosphere, and bursts of radio energy similar to those produced by lightning discharges that often occur in the plumes of erupting volcanoes on Earth.
- Venus has more volcanoes than any other planet in the solar system. Over 1600 major volcanoes or volcanic features are known (see map), and there are many, many more smaller volcanoes. (No one has yet counted them all, but the total number may be over 100,000 or even over 1,000,000). These volcanoes come in a variety of forms.
Active volcanoes in the Solar System
Mount Olympus on Mars is the largest known volcano in the entire Solar System, Venus is dotted with thousands of volcanic features, and Io is the volcanically most active place in the System.
- Shield volcanoes: Venus vs. Earth: This graphic compares the geometry of a large shield volcano from Venus with a large shield volcano from Earth. Shield volcanoes on Venus are usually very broad at the base and have gentler slopes than the shield volcanoes found on Earth.
- 1. Shield volcanoes are a common volcanic feature on Venus. The Hawaiian islands are a good example of this feature on Earth. 2. Lava domes are found both on Venus and Earth, and are the result of upwelling magma pushing up on the surface. 3. Lava channels on Venus are analogous to rilles on the Moon
- In summary, the large shield volcanoes on Venus are several times as wide as those on Earth and they have a much gentler slope. A relative size comparison of volcanoes on the two planets is shown in the accompanying graphic - which has a vertical exaggeration of about 25x.
- Volcanology of Venus. It has a surface that is 90% basalt, and about 65% of the planet consists of a mosaic of volcanic lava plains, indicating that volcanism played a major role in shaping its surface. There are more than 1000 volcanic structures and possible periodic resurfacing of Venus by floods of lava.
Is there evidence of a volcano on Venus?
- Evidence bolstering very recent volcanism on Venus has recently been uncovered, though, right here on Earth. Lab results showed that images of surface lava would become dim in the infrared in only months in the dense Venusian atmosphere, a dimming not seen in ESA's Venus Express images.
- There is no single material for a better shield against the venusian environment. A sandwich of several materials is neccessary to shield against high pressure, high temperature and the sulfuric acid. A very thick and heavy shield would increase duration by some more hours but would be too heavy for launch, flight and landing.
