  Observations of multi-wavelength and therefore height-dependent information
following events throughout the solar atmosphere and unambiguously assigning a
relation between these rapidly evolving layers are rare and difficult to
obtain. Yet, they are crucial for our understanding of the physical processes
that couple the different regimes in the solar atmosphere. We characterize the
exploding granule event with simultaneous observations of Hinode
spectroplarimetric data in the solar photosphere and Hinode broadband CaIIH
images combined with Interface Region Imaging Spectrograph (IRIS) slit spectra.
We follow the evolution of an exploding granule and its connectivity throughout
the atmosphere and analyze the dynamics of a magnetic element that has been
affected by the abnormal granule. In addition to magnetic flux maps we use a
local correlation tracking method to infer the horizontal velocity flows in the
photosphere and apply a wavelet analysis on several IRIS chromospheric emission
features such as MgIIk2v and MgIIk3 to detect oscillatory phenomena indicating
wave propagation. During the vigorous expansion of the abnormal granule we
detect radially outward horizontal flows, causing, together with the horizontal
flows from the surrounding granules, the magnetic elements in the bordering
intergranular lanes to be squeezed and elongated. In reaction to the squeezing,
we detect a chromospheric intensity and velocity oscillation pulse which we
identify as an upward traveling hot shock front propagating clearly through the
IRIS spectral line diagnostics of MgIIh&k. Conclusion: Exploding granules can
trigger upward-propagating shock fronts that dissipate in the chromosphere.
