Recent volcanic activity spotted by NASA on Mars & nbsp
- Volcanoes debris was found to be due to pyroclastic flow caused by massive pressure below the surface.
- This effect can be observed around Olympus Mons on Mars, the highest mountain in our solar system.
- Can this discovery lead to others that can show us how to survive on Mars in the future?
The latest observations show evidence of volcanic eruptions over the past 50,000 years on the planet. It sounds like a lot, but it’s a short time if you look at the big picture and the age of the planets. The first recorded human appearance was observed around 300,000 years ago, 98.8% of the time after the Big Bang, so volcanic eruptions on Mars have occurred less than 20% of the time since humans first appeared. on earth.
The first records of volcanic activity on Mars can be seen four billion years ago, but this activity appears to be spaced, unlike recent findings. Smaller eruptions were also recorded 4 million years ago. Until now, there was almost no evidence to suggest that volcanic activity, as well as other geological activity, has continued since then.
Elysium Planitia, a plain on the equator of Mars, has been recorded to show lava streams fed by fissures that range from 500 million to 2.5 million years ago. New geological activity has been noticed south of this location with several major volcanoes showing signs of recent activity. Eruption debris was seen within a 32-kilometer or 20-mile radius.
The debris was found to be due to pyroclastic flow caused by massive pressure below the surface. One of the most popular cases of this force on Earth is what happened to the city of Pompeii and Herculaneum. Mars showed several examples of such events over 3 billion years ago around Olympus Mons, which is the largest mountain in our solar system and was taller than all other Martian volcanoes. Water, melted from the permafrost on the surface, mixing with the seeping magma can cause an explosive pressure change and result in such an effect. Water and magma can cause an extremely volatile reaction similar to pouring an accelerator on a fire. The force is so powerful that debris was thrown 10 kilometers into the air.
