Brief: 30 August 2026
292 incidents were recorded worldwide on Sunday, 30 August 2026 across 63 countries, 12 of them rated severe or extreme. Earthquakes were the most common category. 1 record was rated severe or extreme by sources that monitor the whole world, the most serious of them M5.8 Earthquake — Kermadec Islands, New Zealand [Sea: New Zealand]. Separately, 11 severe weather warnings were in force across 3 countries, almost all of them in the United States and Europe, the only places that publish such warnings as open feeds. 43% of the day's records came from hazard categories with no official feed anywhere, meaning they exist only because a journalist reported them.
Rated severe by a worldwide source 1
Every record this day that a globally-monitoring source rated severe or extreme — not a top ten. Below that rating the day held hundreds of equally-graded records, and putting eight of them in an order would be inventing a ranking the data does not contain. Severe-weather warnings are listed separately further down, because only the United States and Europe publish them and mixing the two turns a world list into a list of American counties.

Severe weather warnings
11 severe or extreme weather warnings were in force across 3 countries that day. These sit apart from the ranking above because the United States, the 38 European countries in Meteoalarm and only a handful of other national services publish warnings as open feeds — so this count rises when it storms in Ohio and cannot move at all when it storms in Bangladesh.
What the day was made of
Where this day came from
43% of the day's records are hazards with no official real-time feed anywhere in the world.
165 records came from instruments and official feeds — seismic networks, satellites, warning services. 127 exist only because a journalist wrote something.
That second number is the honest measure of this brief's blind spot: it is thinnest exactly where local media is thinnest, and a quiet country here is not evidence of a quiet day there. The per-hazard breakdown →
What this brief will not tell you
Whether this was a busy day or a quiet one.
Daily totals on this site have run from 24 to 4,237, and almost none of that spread is the world — it is our own monitoring changing: the collection schedule, a timezone fix, and three new feeds added in September.
Comparing one day against another would measure our instruments and call it news. That comparison becomes possible once the source list has been stable for a month. The same reasoning, at greater length →
