According to an article released from NASA, scientists are developing a better understanding of "sunquakes" as they appear in time series photographs.

Scientists have long believed that gravitational powers or heating of the outer atmosphere, where the flare happens, drive sunquakes. These waves were meant to sink deep through the Sun's inner surface. However, recent findings have found something else when leveraging knowledge from the NASA Solar Dynamics Observatory (SDO).

SDO observed in July 2011 a Sunquake in a relatively powerful solar fire with peculiar sharp ripples. Waves that induced these rays to return to their source were monitored by scientists using a tool called helioseismic holography. In order to map electromagnetic waves from a number of other sun sources, this method used by SDOs Helioseismic and magnet imaging to measure how the solar surface shifted.

The scientists saw the ripples from below the solar surface directly after a flare instead of the waves heading towards the Sun. Acoustic sources are about 700 km below the surface of the sun and are not above the surface, as previously believed, as findings are published in the Astrophysical Journal Letters journal.

The science community assumes that these waves were driven by an immense source, induced by the sun's flares in the above atmosphere. The new results could clarify the mystery of sunquakes for a long time: why some of the features appear very different from the flares they cause.

The scientists have not yet correctly established what process really triggers sunquakes, but the findings suggest that they undoubtedly have their source below the soil. In order to see whether they have similarly underwater origins, the researchers intend to begin digging for a cause by looking at other sunquakes.
