Terra · live data

Earth.

Space weather, earthquakes, sea level — and your local sky.

Earth sits inside the Sun's atmosphere and on top of a restless crust. This page combines the live geomagnetic Kp index and solar wind from NOAA SWPC, recent earthquakes from the USGS, sea level from NOAA tides, and your local weather from Open-Meteo — so the planet's current state fits on one screen.

What this means

Global geomagnetic disturbance, 0–9. Green <4 quiet, yellow 4 unsettled, orange 5–6 storm (G1–G2), red ≥7 strong storm. Bars = last 24h in 3-hour bins.

What this means

Solar-wind magnetic field at L1. Bz negative (south) opens reconnection with Earth's field and drives storms; Bz positive (north) shields. Bt is total field strength.

Density

— p/cm³

What this means

Plasma streaming from the Sun. Background ~300–500 km/s; ≥600 km/s = high-speed stream from a coronal hole; sharp jumps signal a CME shock. Higher density amplifies impact.

S. pole drift

~9 km/yr

What this means

Reference values for Earth's main field generated by the molten outer core. Per NOAA/BGS WMM 2025, the north magnetic pole now drifts about 36 km/yr toward Siberia — a marked slowdown from the ~55 km/yr peak in the 2000s — while the south pole drifts ~9 km/yr.

What this means

Moment magnitude is logarithmic — each step is ~32× more energy. M2–3 felt locally, M5 damaging near epicenter, M6+ widely destructive, M7+ regional. Shallow quakes (<70 km) cause more surface shaking than deep ones. 🌊 = tsunami flag.

What this means

Total rise since the start of satellite altimetry (1993), reflecting NASA JPL's TOPEX / Jason / Sentinel-6 record through 2025. Rate is the current trend; acceleration means the rate itself is increasing. "Thermal" = expansion of warmer water; "Ice melt" = water added from glaciers and ice sheets (IPCC AR6). Greenland / Antarctica figures are net mass loss per year (GRACE-FO). Arctic sea-ice minimum is the September extent (NSIDC). Ocean heat uptake in zettajoules (10²¹ J) per year.
