In 1991, Mount Pinatubo erupted in the Philippines at the same time that a massive tropical storm wreaked havoc in the area. The pyroclastic surge, though just 5mm thick at its extremities, had nonetheless covered 95 per cent of the track. Cronin calculates from past studies of steam-driven eruptions on Whakaari that this surge would have burst from the crater at 300C and 100km/hour, losing force and heat in the ambient air as it rolled east. Citizens also helped with a block-by-block cleanup effort. Residents near the coast of the North Island may experience some ash fall and could smell some of the volcanic gases, geophysicist Dr Jessica Johnson said, while a nearby marine reserve could also be affected. They were often photographed as minute specks against vast up-rushing columns of steam, or in front of dark umbrellas of mud thrown up by the vents. Eruptions can also shatter the solid rock of the magma chamber and volcanic mountain itself. As it fell, the rock, weakened by heat and saturated with water, mutated from an avalanche into a highly fluid lahar (a violent type of mud or debris flow), which ran for more than 1km eastward to the sea, burying the 11 miners and destroying the sulphur factory.
