Earthquakes on the Moon? The Shocking Scientific Truth About Moonquakes

Most people associate earthquakes only with Earth. But scientists have confirmed that the Moon also experiences seismic activity, known as moonquakes. These mysterious tremors reveal surprising facts about the Moon’s internal structure and evolution.

What Are Moonquakes?

Moonquakes are vibrations or tremors that occur beneath the lunar surface. Unlike Earth’s earthquakes, which are usually caused by tectonic plate movement, moonquakes originate from different processes.

How Were Moonquakes Discovered?

During NASA’s Apollo missions, astronauts placed seismometers on the Moon. These instruments recorded thousands of seismic events between 1969 and 1977, proving that the Moon is not geologically dead.

Types of Moonquakes

Scientists have identified four main types:

• Deep Moonquakes – Caused by tidal forces from Earth’s gravity

• Shallow Moonquakes – Stronger and more dangerous

• Thermal Moonquakes – Triggered by extreme temperature changes

• Meteorite Impact Quakes – Resulting from space rocks hitting the surface

How Strong Are Moonquakes?

Some shallow moonquakes can reach magnitudes comparable to moderate earthquakes on Earth. Because the Moon lacks water and active plate tectonics, these vibrations can last much longer.

Why Moonquakes Matter

Studying moonquakes helps scientists:

• Understand the Moon’s core

• Learn about planetary formation

• Prepare for future lunar missions

Seismic data is essential for building safe lunar bases.

What This Means for Future Moon Exploration

As space agencies plan long-term human presence on the Moon, understanding seismic risks will be crucial for designing structures that can withstand moonquakes.
