Seismic activity map, live from the USGS feed
Recent earthquake epicenters, sized by magnitude.
A fault map shows where the ground can move; a seismic activity map shows where it recently did. Events are drawn as rings scaled to magnitude, so energy is visible before the label is read — an M5.2 does not look like an M2.8.

Why Seismic Activity matters
Induced seismicity near wastewater injection has changed the risk picture in parts of the West faster than hazard maps have been revised. Recent-event clustering is the leading indicator, and it matters to both the operator causing it and the facility being sited nearby.
Questions Seismic Activity answers
- Has there been recent seismicity near this site?
- Is the pattern consistent with induced seismicity from nearby injection?
- How does activity here compare to a candidate site two counties over?
What is in the Seismic Activity data
Coverage: Western US events from the national catalog. Source dataset: Earthquake catalog — recent events.
| Field | What it tells you |
|---|---|
| Magnitude | Event magnitude — the one attribute on the entire map allowed to drive marker size. |
| Depth | Hypocenter depth, which separates shallow induced events from deep tectonic ones. |
| Event time | When the event occurred. |
| Place | USGS place description for the epicenter. |
How we serve Seismic Activity
The seismic bullseye is the one sanctioned exception to the platform's fixed marker size, because there the size is the data: rings scale with magnitude. Every other layer holds a constant radius so nothing else visually outranks its neighbors.

Who uses Seismic Activity
Data Centers & AI Infrastructure
Power, water, fiber and permitting risk for every candidate site — before you send anyone to look at it.
Energy Development
Route corridors, site generation, and clear the environmental picture before the first landowner call.
Industrial & Manufacturing Siting
The same constraint stack as a data center, weighted for process load instead of compute.
Mining & Exploration
Deposits, active claims, protected land and the water to run a mine — on one map.
