  1. Pyroclastic surge

    A pyroclastic surge is a fluidized mass of turbulent gas and rock fragments which is ejected during some volcanic eruptions. It is similar to a pyroclastic flow but it has a lower density or contains a much higher proportion of gas to rock ratio, which makes it more turbulent and allows it to rise over ridges and hills rather than always travel downhill as pyroclastic flows do. The speed of pyroclastic density currents has been measured directly via photography only in the case of Mount St. Helens, where they reached 90 – 130 m/s. Estimates of other modern eruptions are around 100 m/s. Pyroclastic flows may generate surges. For example, the city of Saint-Pierre on the Caribbean island of Martinique in 1902 was overcome by one. Base surge was first recognized after the Taal Volcano eruption of 1965 in the Philippines, where a visiting volcanologist from USGS recognized the phenomenon as congruent to base surge in atomic explosions. These surges are expanding rings of turbulent mixture of fragments and gas that surge outward at the base of explosion columns. Base surges, which are now called pyroclastic surges when relating to volcanoes, are more likely generated by the interaction of magma and water or phreatomagmatic eruptions.
