The 2013 Lushan Earthquake in China Tests

Following the devastating 2008 Wenchuan earthquake that ruptured the central–northern segments of the Longmenshan fault in Sichuan, China, many studies assessed its impact on other major faults in this region (e.g., Parsons et al., 2008; Toda et al., 2008). On 20 April 2013, theMw 6.6 Lushan earthquake ruptured the southern segment of the Longmenshan fault, allowing these assessments to be test...

Diffraction Tomography of the Disturbed Ionosphere Based on GPS Scintillation Data

A new inverse diffraction algorithm has been developed to estimate the fine-scale ionospheric electron density variations that cause equatorial scintillation in GPS signals. This work is part of an effort to image the disturbed ionosphere in order to better understand scintillation from a scientific standpoint. The new algorithm relies on a physical model of how electron density irregularities ...

November 2003 event: effects on the Earth’s ionosphere observed from ground-based ionosonde and GPS data

Intense late-cycle solar activity during October and November 2003 produced two strong geomagnetic storms: 28 October–5 November 2003 (October) and 19– 23 November 2003 (November); both reached intense geomagnetic activity levels, Kp=9, and Kp=8+, respectively. The October 2003 geomagnetic storm was stronger, but the effects on the Earth’s ionosphere in the mid-latitude European sector were mor...

22 Earthquake Early Warning with GPS Data

The combined use of seismic and geodetic observations is now a common practice for finite-fault modeling and seismic source parametrization. With the advent of highrate 1Hz GPS stations the seismological community has recently begun looking at GPS data as a valid complement to the seismic-based methodologies for Earthquake Early Warning (EEW). In the standard approaches to early warning, the in...

Precise Ionosphere Modeling Using Regional GPS Network Data

The ionosphere affects the electromagnetic waves that pass through it by inducing an additional transmission time delay. The ionosphere influence has now become the largest error source in GPS positioning and navigation after the turn-off of the Selective Availability (SA). In this paper, methods of 2D gridbased and 3D tomography-based ionospheric modeling are developed based on regional GPS re...
