New observations of the Mars reveal evidence of volcanic eruptions on that world during the last 50,000 years.
Three to four billion years before our time, volcanoes erupted across the surface of the Red Planet.
Smaller, more localized, eruptions continued until three million years ago.
But, little evidence was found suggesting that volcanoes onMarsremain geologically active today.
Volcanic activity on Mars peaked during the Noachian and Hesperian periods but has continued since then in isolated locales.
This broad plain, which lies just south of the volcanic province of Elysium, includes several major volcanoes.

When we first noticed this deposit, we knew it was something special.
A recent study has also shown similaractive volcanoes on the surface of Venus.
A look at the InSight Mission.
When water mixes with magma, its like pouring gasoline on a fire, Moitra said.
This particulareruptionmay have lifted debris almost 10 kilometers (six miles) into the air the height of Mt.
The new quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5.
The two pairs of quakes took place roughly oneMartianyear (two Earth years) apart.
Both sets of readings were recorded during summer at the landing site.
Its wonderful to once again observe marsquakes after a long period of recording wind noise.
These are typically found in two forms some are similar to those on Earth traveling directly through the planet.
Others are more Moon-like, taking place in scattered regions.
All four Cerberus Fossae quakes were of the terrestrial variety.
Exploring Mars with Dr. Fatima Ebrahimi and Dr. Kirsten Siebach.
Prior to InSight landing on the surface of Mars, researchers suggested Marsquakes might occur within Cerberus Fossae.
Here onEarth, geologists have found evidence that large earthquakes can trigger volcanic eruptions.
This discovery could also hold implications for answering questions about life past or present on Mars.
