Global Earthquake Update: Thursday, December 18, 2025 Report

The earthquake activity report for December 18, 2025, reveals significant seismic events across the globe. Over a 24-hour period, a total of 670 earthquakes were recorded, including five with a magnitude of 5.0 or higher.

Global Earthquake Update: Thursday, December 18, 2025

Here are the key statistics from the recent seismic reports:

• Magnitude 5.0+: 5 earthquakes
• Magnitude 4.0+: 41 earthquakes
• Magnitude 3.0+: 193 earthquakes
• Magnitude 2.0+: 431 earthquakes

Notably, there were no earthquakes recorded at a magnitude of 6.0 or higher. The total estimated seismic energy released amounted to approximately 8.3 x 10¹³ joules, which is comparable to 22.9 gigawatt hours or 19,732 tons of TNT, roughly equivalent to the energy of one quake of magnitude 6.1.
