Tsunami Bores in Kitakami River
Elena Tolkova, Hitoshi Tanaka
The 2011 Tohoku tsunami entered the Kitakami river and propagated there as a train of shock waves, recorded with a 1-min interval at water level stations at Fukuchi, Iino, and the…
Comparison of Helioseismic Far-side Active Region Detections with STEREO Far-Side EUV Observations of Solar Activity
P. C. Liewer, J. Qiu, C. Lindsey
Seismic maps of the Sun's far hemisphere, computed from Doppler data from the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) are now being use…
Are all flare ribbons simply connected to the corona?
Philip Judge, Alin Paraschiv, Daniela Lacatus +2
We consider the observational basis for the belief that flare ribbons in the chromosphere result from energy transport from the overlying corona. We study ribbons of small flares u…
Helioseismic Holography of Simulated Sunspots: dependence of the travel time on magnetic field strength and Wilson depression
T. Felipe, D. C. Braun, A. C. Birch
Improving methods for determining the subsurface structure of sunspots from their seismic signature requires a better understanding of the interaction of waves with magnetic field…
Sensitivity of Helioseismic Measurements of Normal-mode Coupling to Flows and Sound-speed Perturbations
Shravan M. Hanasoge, Martin Woodard, H. M. Antia +2
In this article, we derive and compute the sensitivity of measurements of coupling between normal modes of oscillation in the Sun to underlying flows. The theory is based on first-…
Tsunami penetration in tidal rivers, with observations of the Chile 2015 tsunami in rivers in Japan
Elena Tolkova
An extensive data set of water level measurements of the September 2015 Chilean tsunami in rivers in Japan and a new methodology for data processing are used to verify that tsunami…
