Draw rectangle on map to select stations, zoom in/out to focus on regions, then click on the station in the sidebar to see realtime slant TEC. Station background noise level from the last 24 hours is shown as () - Low (<0.05TECU), () - Medium (0.05-0.15 TECU), () - High (>0.15 TECU) , or () - Not Available. Click here for global noise statistics for the last eight weeks.
Near-real-time TEC data from GUARDIAN are available through the NASA Crustal Dynamics Data Information System (CDDIS)
On July 29, 2025 at 23:25 UTC, a Mw 8.8 earthquake off the coast of the Kamchatka Peninsula (Russian Federation) triggered a significant tsunami in the Pacific Ocean.
VIEW EXAMPLEOn May 10-13, 2024, the most severe geomagnetic storm (Kp ~9) since 1989 impacted Earth, triggering severe ionospheric disturbances. These disturbances are visible in the noise in TEC time series around the world.
VIEW EXAMPLEOn November 22, 2023, a Mw 6.7 earthquake struck the Republic of Vanuatu and generated a small tsunami.
VIEW EXAMPLEOn February 06, 2023, two high-magnitude earthquakes (Mw 7.8 and 7.5) struck the Kahramanmaraş region (Republic of Türkiye), leading to more than fifty thousand deaths in the Republic of Türkiye and Syria.
VIEW EXAMPLEOn January 15, 2022, the Hunga volcano on the islands of Hunga Tonga and Hunga Ha'apai erupted, producing the largest ionospheric signal ever observed. Atmospheric waves produced by the eruption circled the globe several times.
