Variation of electron density before large earthquakes in Southeast Asia observed by CHAMP satellite from 2004 to 2009

This project studies the behaviour of the pre-earthquake (EQ) ionospheric parameter by analysing the variation of electron density (Ne) measured by the CHAMP satellite, which is one of the satellites that collect in-situ data of Ne in the ionosphere. Data from two weeks before the main shock of...
