Off-Nadir Delta

Facility Exposure Check

Paste a list of ports, plants or sites. See what was reported or measured near each in the last 30 days — and which had nothing — without an account.

Quick answer — what this checks

A facility exposure check takes up to 10 sites as names with latitude and longitude, draws a 1 km radius around each, and lists the events in Delta’s sources from the last 30 days that are linked to it — reports naming a registered facility inside the radius, reports placed precisely inside it, and measured events. Sites with no linked event are counted as having nothing in Delta’s sources, which is not a statement that nothing happened there. It is built for teams that keep a list of ports, terminals or plants and want to know when something happens near one of them.

CSV or a paste from a spreadsheet. A header row is optional.

Hand-picked lists of ports from the location registry, each with the same check run across the whole list.

Frequently Asked Questions

What does the facility exposure check show?▼
For each site you paste, the events in Delta's sources from the last 30 days that are linked to it: reports that name a registered facility within the radius, reports placed precisely inside the radius, and measured events such as heat at a facility, earthquakes near facilities or ship-traffic anomalies. It lists the most recent few for each site and says how many sites had nothing.
Does “nothing in Delta’s sources” mean the site is safe?▼
No. It means no report or measurement linked to that place reached Delta in the window. Something can happen without being reported, and a report can be placed too coarsely to be tied to one site.
How is a site matched to events?▼
A site is a point with a radius — 1 km unless you watch it with another one. Events are matched in two ways: through the location registry, when the reporting names a port, plant, base or other registered facility inside the radius, and by position, when an event was placed precisely enough to fall inside the radius. An event placed only at the level of a city or a country is matched only when its reporting names a registered facility inside the radius.
Are the event titles verified?▼
No. Each title summarises what the reporting said. The event page lists the articles behind it and how precisely its place is established.
Why are some measured events shown without a place name?▼
The detail of measured events — which facility, how strong — is part of the full account of each event, which not every plan includes. Without an account, you see that something was measured near the site and when.
Can I check more than ten sites?▼
Not on this page. In the Watchlist you can paste a longer list once, keep it as a named list, and get one summary email a day for the whole list. The number of sites you can watch depends on your plan; see Pricing.
Is there an API?▼
Yes, for watching: a list of sites can be created in one request over the REST API or with watches.create_many in the Python SDK, and read back with the Watchlist endpoints. The API reference has the details.
