6.5 Earthquake Weekly

How many 6.5 or above earthquakes worldwide  September 7 - September 13?

This market will resolve "Yes" if the United States Geological Survey (USGS) (https://www.usgs.gov/programs/earthquake-hazards/lists-maps-and-statistics) reports at least one earthquake of moment magnitude (Mw) 7.0 or greater with an epicenter located within the state of California by December 31, 2026 at 11:59:59 PM ET. Otherwise, this market will resolve "No".

The state of California includes the entirety of California as recognized under U.S. law including offshore areas within California's territorial boundaries. Earthquakes occurring on the California border must have their USGS-listed epicenter coordinates fall within California's boundaries.

Any individual event meeting the magnitude and location criteria resolves the market "Yes", regardless of whether it is classified as a mainshock, aftershock, or foreshock.

Resolution will be based on the USGS's final reviewed magnitude, not preliminary estimates, regardless of when that review is published, but the qualifying earthquake needs to have occurred within California by December 31, 2026 at 11:59:59 PM ET. This market will resolve based on official information from USGS, however, an overwhelming consensus of credible reporting confirming a qualifying earthquake may also resolve this market in an instance where USGS becomes unavailable. 

Will California experience a 7.0 or above magnitude earthquake in 2026?

This market will resolve according to the number of natural volcanic eruptions with a Volcanic Explosivity Index (VEI) of 4 or higher between January 1 and December 31, 2026, 11:59 PM ET.

The primary resolution source will be the Smithsonian Institution Global Volcanism Program (GVP: https://volcano.si.edu/), specifically the cumulative figures for 2026 for VEI 4, VEI 5, and VEI 6 released on the page currently titled "Eruptions Avg 2000-2024 (N/T)" (https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear) as of March 31, 2027, 12 PM ET. Any prior updates will not be considered finalized.

If this dataset has not been updated to include all relevant events by March 31, 2027, or if the Smithsonian GVP becomes permanently unavailable, this market may resolve based on a consensus of credible scientific sources, including the U.S. Geological Survey (USGS), national or regional volcanic observatories, or credible reporting of a scientific consensus.

Note: Smithsonian Institution Global Volcanism Program databases, which include eruptions that reached the relevant threshold prior to this market’s timeframe (e.g., https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear&checkyear=2025), will not be considered.

How many large volcano eruptions (VEI ≥4) in 2026?

This market resolves to "Yes" if the United States Geological Survey (USGS) reports an earthquake with a preferred magnitude of 6.0+ attributed to the listed country, with an origin time between September 1, 2026, 12:00 AM ET and September 30, 2026, 11:59 PM ET, by October 4, 2026, 12:00 AM ET. Otherwise, that market resolves "No".

A qualifying earthquake must be counted for a country's market only if USGS attributes its location to that country in the event's location description, lists the earthquake with a preferred magnitude of 6.0 or higher, and lists it as occurring within the specified timeframe. Earthquakes without a preferred magnitude classification will not qualify.

Revisions to a reported earthquake's underlying data, such as preferred magnitude and country attribution, will be considered until the end of the third calendar day after that earthquake's origin time (ET); revisions made after that time will not be considered. If a reported earthquake still qualifies at the end of its revision period, this market will resolve to "Yes" at that time, without remaining open until October 4, 2026, 12:00 AM ET. If it no longer qualifies at that time, this market will remain open until another qualifying earthquake is reported or the market's end date is reached, whichever comes first.

If an earthquake with an origin time within a market's window has not yet appeared on the resolution source by October 4, 2026, 12:00 AM ET, this market end date may be extended for up to one week after October 4, 2026 and will resolve based on the preferred magnitude, country attribution, and timestamp of the event as of the end of its revision period (per the revision rules above), provided that revision period falls within the extension window. If the revision period would extend beyond the extension window, this market will resolve based on the data available at the end of the extension period. If the relevant data is not released by the end of the extension period, this market will resolve based on the data released up until that point.
The resolution source for this event is the United States Geological Survey (USGS) Earthquake Hazards Program earthquake catalog (https://earthquake.usgs.gov/earthquakes/search/), and only data released by USGS will be considered, regardless of other sources.

If the resolution source becomes temporarily unavailable, the market will remain open until it resumes; if it remains unavailable through October 4, 2026, 12:00 AM ET, this market will resolve to "No".
