About this view

Earthquake24 production displays U.S.-focused official volcano activity notices from USGS HANS.

Status is source-specific

Alert terminology differs between organisations and countries. A displayed HANS notice does not confirm that an eruption is occurring when you view the map, and a map marker is never a safe-distance boundary.

Source limits

HANS provides at most seven days of source history and is not globally complete. Earthquake24 does not ingest, cache or display GDACS events in production and is not a volcano observatory or civil-protection authority.
