2027年之前發生9.0級或以上地震？

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.

2026年有多少大型火山爆發（ VEI ≥ 4 ） ？

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. 

加州在2026年會發生7.0級或以上的地震嗎？

A "megaquake" is defined as an earthquake with a magnitude of 8.0 or greater.

This market will resolve to “Yes” if 1 or more earthquakes with a magnitude of 8.0 or higher occur anywhere on Earth between market creation and August 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.

The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program (https://earthquake.usgs.gov/earthquakes/browse/significant.php#sigdef).

If an earthquake of substantial size has occurred within this market's timeframe but not yet appeared on the resolution source, this market may remain open until the end of the seventh day after the resolution time, or until the earthquake in question otherwise appears on the resolution source. If such an earthquake has not appeared on the resolution source by that date, another credible resolution source will be used.

After a qualifying earthquake is registered, this market will remain open for 24 hours to account for any revisions to its recorded magnitude. After 24 hours, this market will resolve according to the latest provided data.

8月31日前發生超級地震？

For the purposes of this market, a Category 5 hurricane is a hurricane with maximum sustained winds of 157 mph or higher, as described at https://www.nhc.noaa.gov/aboutsshws.php, and a hurricane landfall is said to occur when the hurricane's surface center intersects with the coastline, as described at https://www.nhc.noaa.gov/aboutgloss.shtml#LANDFALL.
