Brace yourself, because the Earth has been quite active! This report, covering Saturday, October 18, 2025, provides a snapshot of global seismic activity. Let's dive in and see what's been shaking around the world.
In the last 24 hours, there's been a flurry of seismic activity:
- 4 earthquakes with a magnitude of 5.0 or higher.
- 52 earthquakes with a magnitude between 4.0 and 4.9.
- 143 earthquakes with a magnitude between 3.0 and 3.9.
- A whopping 341 earthquakes with a magnitude between 2.0 and 2.9.
This totals to 540 earthquakes! This report is updated hourly, so the numbers might shift.
The total estimated seismic energy released is a staggering 3.7 x 10^13 joules! To put that into perspective, that's equivalent to 10.1 gigawatt hours of energy, or the explosive power of 8731 tons of TNT, which is roughly 0.5 atomic bombs!
