Status Candidate Method Review state Last review
blocked Smithsonian GVP gvp_usgs_colocation:us6000sswe-dempo-261230 smithsonian-gvp agent-edited

Reviewed Dempo co-location; USGS event is M4.7 with tsunami=0 and no PAGER alert, while GVP describes a separate 15 April phreatic eruption.

No primary source connects the earthquake to Dempo activity; proximity at 179.7 km is not enough and causation language is forbidden by the profile.

routine NOAA SWPC swpc_xray_peak:2026-04-26T22:57Z-xray-long noaa-swpc anomaly-detection

Reviewed SWPC X-ray candidate; the old 2026-04-26T22:57Z peak aged out and the current 24h peak is only 1.052e-5 W/m2.

Does not clear anomaly-detection baseline: current 24h peak is below the trailing-14d q99 of 1.346e-5 W/m2 and is not record-breaking.
