The paper presents results of a search for helioseismic events (sunquakes) produced by M-X class solar flares during Solar Cycle 24. The search is performed by analyzing photospheric Dopplergrams from Helioseismic Magnetic Imager (HMI). Among the total number of 500 M-X class flares, 94 helioseismic events were detected. 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 weak. Our study also revealed that only several active regions were characterized by the most efficient generation of helioseismic waves during flares. We found that the sunquake power correlates with the maximum value of the soft X-ray flux time derivative better than with the X-ray class, indicating that the sunquake mechanism is associated with high-energy particles. We also show that the seismically active flares are more impulsive than the flares without helioseismic perturbations. We present a new catalog of helioseismic solar flares, which opens opportunities for performing statistical studies to better understand the physics of sunquakes as well as the flare energy release and transport.

太阳周期的日震 24

本文介绍了在太阳周期 24 期间搜索由 MX 级太阳耀斑产生的日震事件（太阳地震）的结果。该搜索是通过分析来自日震磁成像仪 (HMI) 的光球多普勒图来执行的。在 500 次 MX 级耀斑总数中，检测到 94 次日震事件。我们的分析表明，许多强烈的太阳地震是由低 M 级（M1-M5）的太阳耀斑产生的，而在一些强大的 X 级耀斑中，日震波没有被观测到或很弱。我们的研究还表明，只有几个活动区域的特点是在耀斑期间最有效地产生日震波。我们发现太阳地震功率与软 X 射线通量时间导数的最大值的相关性比与 X 射线等级的相关性更好，表明太阳地震机制与高能粒子有关。我们还表明，地震活跃的耀斑比没有日震扰动的耀斑更具冲动性。我们提出了一个新的日震太阳耀斑目录，这为进行统计研究以更好地了解太阳地震的物理学以及耀斑能量释放和传输提供了机会。
