  We report the simultaneous presence of chromospheric umbral flashes and
associated umbral waves, and propagating coronal disturbances, in a sunspot and
related active region. We have analyzed time-distance maps obtained using the
observations from Atmospheric Imaging Assembly (AIA) on-board Solar Dynamics
Observatory (SDO). These maps show the simultaneous occurrence of different
sunspot oscillation and waves such as umbral flashes, umbral waves, and coronal
waves. Analysis of the original light curves, i.e., without implementing any
Fourier filtering on them, show that the amplitudes of different sunspot waves
observed at different atmospheric layers change in synchronization with the
light curves obtained from the umbral flash region, thus demonstrating that
these oscillations are modulated by umbral flashes. This study provides the
first observational evidence of the influence of sunspot oscillations within
the umbra on other sunspot waves extending up to the corona. The properties of
these waves and oscillations can be utilized to study the inherent magnetic
coupling among different layers of the solar atmosphere above sunspots.
