How this service works
Retrieves the earthquakes within a radius and time window of a point and turns them into an exposure figure. Each event contributes according to its magnitude and its distance, using an explicit formula that is returned with the result: energy scales exponentially with magnitude and attenuates with distance, so a distant large event and a near small one can contribute comparably, which is the behaviour that makes a single count useless.
Output
Returns a numeric seismic exposure figure representing the cumulative earthquake energy experienced at the given point, along with the list of contributing earthquake events, each weighted by magnitude (exponential scaling) and distance (attenuation), plus the explicit mathematical formula used to compute the score.
Example use cases
Site risk assessment for construction
“I'm evaluating a construction site at 34.05° N, 118.25° W — can you calculate the seismic exposure score for that location over the last 90 days within 250 km so I can understand the cumulative earthquake energy it's been exposed to?”
Insurance underwriting seismic exposure
“For underwriting purposes, I need the weighted seismic exposure figure for coordinates 35.6762° N, 139.6503° E over the past 12 months within 500 km, including the formula used to combine magnitude and distance.”
Real estate due diligence seismic check
“Before buying property at 40.7128° N, 74.0060° W, can you pull the seismic proximity exposure score for that point over the last 6 months within a 150 km radius so I can see how much earthquake activity has accumulated nearby?”
Technical details
Endpoint
POSThttps://natur.halowerk.com/v1/seismic-proximityWhen to prefer
Choose this endpoint when you need a single, quantified seismic exposure score that accounts for both magnitude and distance — not just a raw count of events. It is the right choice for risk assessment, insurance underwriting, site evaluation, or any use case where you need to compare locations by cumulative seismic energy received rather than simple earthquake counts. Prefer it over raw earthquake list endpoints when downstream decisions depend on a defensible, formula-based hazard metric.
Side effects
- No earthquakes found in the specified radius and time window — returns zero exposure or empty event list
- Invalid or out-of-range coordinates — returns validation error
- Radius or time window exceeds allowed limits — returns parameter error
- USGS data source unavailable — may return upstream timeout or partial results
- Malformed request body — returns schema validation error
