Katla Volcano is covered by several hundred meters of ice from the Mýrdalsjökull Glacier in southern Iceland. This active volcano has an eruption interval of 20–90 years, causing massive mud flows, or jökulhlaup, when the subglacial eruptions melt the massive ice cap from below.
Boardwalks are assembled for tourists to navigate the unstable ground and access the Katla Ice caves in safety.
Icebergs on Diamond Beach are battered by the incoming tide.
