USGS significant earthquake alerts by email

Why this feed exists

A major earthquake near a refinery, port, or industrial corridor can disrupt supply chains and reprice insurance and reinsurance exposure within minutes of the event, long before any damage assessment exists. The USGS publishes significant-earthquake data automatically, often within minutes of detection, well ahead of news coverage that waits for confirmed casualty or damage reports.

What each alert includes

The magnitude, location, and depth the moment USGS publishes it, a link to the event page, and a Market read on infrastructure exposure: what energy, industrial, or port facilities sit near the epicenter, the plausible transmission to insurance and reinsurance names, and a plain statement when a quake's location and depth suggest limited economic consequence.

What we filter, honestly

USGS detects thousands of small earthquakes worldwide every week. This feed alerts only on events the USGS itself classifies as significant. That means meaningful magnitude, shallow depth, or proximity to population and infrastructure, so routine seismic background noise never reaches your inbox.
