Desk reading of USGS us7000tgrk
Note
USGS reviewed event us7000tgrk puts a M6.5 mww at 21:23 UTC on September 11 — local morning on the 12th — 126 km NNE of Teluknaga, deep at about 372 km. Tsunami flag 0, PAGER green, DYFI felt responses in the low twenties. The intake seed called it M6.6; the preferred USGS package at promote fetch is 6.5. Deep enough that the Mag looks louder than the shaking usually feels — still the strongest official Java-corridor tick in this intake window.
Attribution: USGS NEIC event us7000tgrk (event page + detail GeoJSON). The Watchers 12 Sep M6.6 piece = intake seed only; magnitude follows USGS preferred 6.5.
Why it matters
This is the interrupt-adjacent pin for the board: Mag clears the Desk ~M6.5 line near Jakarta’s northern approaches, but depth and green PAGER keep it an instrument card rather than a body-bag story.
