The detail behind the day
The equatorial Pacific is the warmest on record.
Earthquakes of magnitude 4.5 or more
Strongest first. Magnitude is a log scale: each whole step is about 32 times more energy. Depth is how far below the surface the quake began; shallow ones shake the ground harder.
| Time (UTC) | Magnitude | Depth | Where | Country |
|---|---|---|---|---|
| 23:17 | 5.9 | 10 km | central Mid-Atlantic Ridge | Open ocean |
| 16:04 | 5.5 | 38 km | near Hamakita, Japan | Japan |

Where most of them struck
4 more happened out at sea, away from any country’s borders.
Counting smaller ones too, 39 earthquakes of magnitude 2.5 or more were logged worldwide. How many small quakes are recorded depends on how many seismometers are nearby, so this number is not compared with other years.

Tropical storms and cyclones
| Alert | Storm | Reported intensity |
|---|---|---|
| NASA tracker | Super Typhoon In-fa | 60 kts |
| Green | Tropical Cyclone 02-20262027-27 GDACS report | Tropical Depression (maximum wind speed of 63 km/h) |
| Green | Tropical Cyclone CEMPAKA-26 (Japan) GDACS report | Tropical Storm (maximum wind speed of 185 km/h) |
| NASA tracker | Tropical Cyclone Murasu | 65 kts |
| Green | Tropical Cyclone PENA-26 GDACS report | Tropical Storm (maximum wind speed of 120 km/h) |
The alert colour reflects the likely effect on people, not just wind speed. Red is the highest; green is a storm with little expected impact.

Floods, weather warnings and other events
United States: severe and extreme warnings
| Hazard | Severe | Extreme |
|---|---|---|
| Winter weather | 43 | 0 |
| Flood | 23 | 0 |
| Wind | 16 | 0 |
| Fire weather | 1 | 0 |
| Other | 1 | 0 |
| Thunderstorm and hail | 1 | 0 |
Each figure is the peak number of warnings in force at once in a state, added across states. It shows scale, not an exact count of separate events.
NASA’s tracker lists 7,168 open wildfires worldwide. They are counted, not listed.
