Ionospheric VTEC anomalies before Ms7.1 Yushu earthquake

Analysis of Ionospheric Vertical Total Electron Content before the 2014 Mw8.2 Chile Earthquake

This paper studies ionospheric vertical total electron content (VTEC) variations before the 2014 Mw8.2 Chile earthquake. VTEC derived from 14 GPS (Global Positioning System) stations and GIM (Global Ionospheric Map) were used to analyze ionospheric variations before the earthquake using the sliding interquartile range method, and results showed that significant positive VTEC anomalies occurred ...

China's health challenges after the Yushu Earthquake.

Urgent monitoring and analysis on Yushu Earthquake using remote sensing

At 7:49 am on April 14, 2010, an earthquake (Ms 7.1) originated (33.2°N, 96.6°E) near Jiegu Town, Yushu Tibetan Autonomous Prefecture, Qinghai Province, China. After the earthquake, we analyzed the geological structure of the disaster region based on the “Beijing-1” images. Using the aerial images after earthquake with high resolution (0.4m) and SPOT ortho-images, we monitored urgently the disa...

Ionospheric characteristics above martian crustal magnetic anomalies

33.02 DPS Conference 2005.09.06 We studied several thousand electron density profiles from the Mars Global Surveyor Radio Science experiment. Electron densities in some of these profiles change significantly over vertical distances as short as 1--2 km, often causing localized ``bite-outs''. These ``anomalous'' profiles are preferentially located above crustal magnetic anomalies. Anomalous featu...
