Does the USGS catalog list at least one earthquake of preferred magnitude 5.0 or greater with an origin time from 2026-09-23T00:00:00Z inclusive to 2026-09-23T06:00:00Z exclusive?

Answer

false
catalog
Use the USGS FDSN event service, worldwide, eventtype=earthquake, minmagnitude=5, with no contributor or geographic filter. Use the preferred magnitude and origin returned by the service; do not substitute a different agency's number or require one particular magnitude scale.
source_1
USGS magnitude-5 query for the six-hour interval: https://earthquake.usgs.gov/fdsnws/event/1/query?format=geojson&starttime=2026-09-23T00%3A00%3A00Z&endtime=2026-09-23T05%3A59%3A59.999Z&minmagnitude=5&eventtype=earthquake&orderby=time-asc
true_rule
Return true if a successful complete catalog response contains at least one qualifying event. Identify its event ID, origin time, preferred magnitude and magnitude type.
false_rule
Return false only if a successful complete catalog query contains zero qualifying events. A timeout, failed request, truncation or unavailable catalog is not an empty result.
time_filter
Filter on event origin time, not publication/update time. USGS endtime is inclusive: query through 2026-09-23T05:59:59.999Z, and independently require time < 2026-09-23T06:00:00Z. A magnitude of exactly 5.0 qualifies.
version_policy
This research test deliberately uses the catalog version retrieved during assessment. Cite its metadata.generated time and preserve the response. Later additions or magnitude revisions may change the catalog answer; it is not a claim about an immutable final catalog or every physical earthquake.
chain_window_role
The block window is a request anchor only. This is off-chain panel evidence. Resolve the event or measurement using the exact observation interval and rules above, not blockchain time or a rolling period.

unavailable_policy
Unavailable, incomplete or conflicting required evidence is not false. Report inability rather than guessing or substituting a different question or source.
disagreement_policy
If members see materially different catalog versions, report that revision conflict instead of presenting the result as a stable historical fact. A funded market needs a precommitted catalog snapshot/version and revision policy.
