The ongoing seismic and volcanic activity in the area and subsequently heavy rainfall as well as low visibility and toxic gases all hampered recovery efforts. Still, monitoring efforts and reports from tourist companies also picked up some geyser-like convulsions at the time, along with an uptick in gas emissions and seismic rumblings. This volcanic debris can reflect incoming solar radiation and absorb outgoing land radiation, leading to a cooling of the Earths temperature. During the 2010 Eyjafjallajokull volcanic eruption, thousands of flights were cancelled due to the volcanic ash cloud that was generated by the eruption.
