WebFeb 17, 2006 · Between 14 and 40 min after the earthquake, TEC enhancements of 1.6–6.9 TEC units (TECU) were observed at subionospheric points located 360–2000 km north of the epicenter. From the time delays of the observed TEC enhancements, we find that the TEC enhancements propagated northward from the epicenter. The IGRF 2000 has been estimated from magnetic measurements taken by the Ørsted sattelite in summer 1999. For this purpose, three models have been derived: The first …
