PPT-Characteristics of Sunquake Events Observed in Solar Cycle 24

Alexander Kosovichev NJIT USA and Ivan Sharykin IKI Russia Helioseismic response to solar flares sunquakes occurs due to localized force orand momentum impacts observed during the flare impulsive phase in the lower atmosphere .

Cycle 24 was relatively weak, but the peak was comparable to or larger than recent cycles and was reached 2015 as a consequence of the development of a large low-latitude unipolar region over several months. . .
