Will a magnitude 5.1 or greater earthquake be recorded in the Japan region (latitude 30–46, longitude 128–146) before July 21, 2026?

🤖 Contexto

YES if the U.S. Geological Survey (USGS) earthquake catalog shows one or more events with reported magnitude 5.1 or greater whose origin time is on or after 00:00 UTC on July 18, 2026 and before 00:00 UTC on July 21, 2026, and whose epicenter lies inside latitude 30 to 46 and longitude 128 to 146 according to the USGS catalog. Otherwise NO. If the USGS event service is unavailable at resolution time, the market will be resolved once the USGS catalog is reachable and the authoritative event list for that interval can be obtained.
