Every second, the Sun ejects 1.5 million tons of material into space at hundreds of miles per second, but Earth's magnetic field protects it from the solar wind.

Characteristics of Higher‐Mode Ambient Noise Rayleigh Waves in Taiwan: Insights from Multicomponent Interferometry #SRL
Scientists find that higher-mode waves correlate with underlying geological structures.

Seismic data are generally contaminated by noise from different sources. If the noise and signal don't share the same frequency, filtering is relatively simple. If they do, a new #BSSA paper considers how to deal with this problem.
