A sunquake is a quake that occurs on the Sun. Seismic waves produced by sunquakes occur in the photosphere and can travel at velocities of 35,000 kilometres per hour (22,000 mph) for …

2021年1月4日 · Scientists have long suspected that sunquakes are driven by magnetic forces or heating of the outer atmosphere, where the flare occurs. These waves were thought to dive …

2006年1月8日 · What is a sunquake? A great deal of energy is released in a large solar flare, as marked for example by RHESSI X-ray and γ-ray observations. In some flares, some of this …

2021年10月20日 · A sunquake might sound like something that would be pitted against a tsunami in a B-level disaster movie, but these ripples on the Sun’s surface aren’t likely to affect us here …

2021年1月8日 · Data from NASA’s Solar Dynamics Observatory shows that seismic activity on the sun is triggered deep beneath the solar surface following flares in the star’s outer atmosphere.

Our analysis has shown that many strong sunquakes were produced by solar flares of low M class (M1-M5), while in some powerful X-class flares helioseismic waves were not observed or were …

2023年9月13日 · Abstract: The first significant sunquake event of Solar Cycle 25 was observed during the X1.5 flare of May 10, 2022, by the Helioseismic and Magnetic Imager (HMI) …

Sientists have shown for the first time that solar flares produce seismic waves in the Sun's interior that closely resemble those created by earthquakes on our planet. The researchers observed …

2011年2月19日 · The X2.2-class solar flare of February 15, 2011, produced a powerful `sunquake' event, representing a seismic response to the flare impact. The impulsively excited …

2024年2月20日 · Scientists are one step closer to figuring out the source of Sunquakes, and the answer may be lurking beneath the surface. In July 2011, a short-lived disturbance originating …
