Monique R. Morgan, The Eruption of Krakatoa also known as Krakatau in 1. On 2. 7 August 1. Krakatoa or Krakatau1 erupted with a force more than ten thousand times that of the atomic bomb dropped on Hiroshima Thornton 1. Wildest Dreams 1990 Torrent' title='Wildest Dreams 1990 Torrent' />The world quickly took notice. Officials reported the eruption via undersea telegraph cables. People thousands of miles away heard the explosion, and instruments around the world recorded changes in air pressure and sea level. In the months that followed, newspapers and journals printed vivid accounts of spectacular sunsets caused by fine particles that the volcano spewed into the upper atmosphere and that circled the globe, gradually spreading further north and south. Wildest Dreams 1990 Torrent' title='Wildest Dreams 1990 Torrent' />The Royal Society, a British academy of scientists, formed a special Krakatoa committee to collect these articles, other eye witness testimony, and more precise data such as barograph readings of air pressure to analyze the material meticulously and to publish a thorough report of their findings. Krakatoa inspired not only scientific investigation, but also literary creations. Gerard Manley Hopkins published a letter describing the Krakatoa sunsets in evocative and figurative language. Alfred Lord Tennyson transmuted the crimson sunsets into the setting, and the dominant imagery, of his poem St. Telemachus. In Blown to Bits, R. M. Ballantyne interwove a detailed, factual account of Krakatoas destruction with an invented tale of exploration, revenge, and romance, centered on fictional characters who narrowly escape the eruption and tsunamis. M. P. Shiel used a volcanic eruption as the major plot device in his last man novel, The Purple Cloud, and, in his depiction of a fictional eruption, Shiel mimicked the central place of the telegraph and the periodical press for scientists and laymens knowledge of Krakatoa.

These visitors may have been foolhardy, but some were quite observant, and later were able to provide valuable data, such as estimates of the size of the crater, the frequency of explosions, and the height of the vapor column.

The reason such a violent eruption occurred at Krakatoa, rather than some other location, was partially understood by late nineteenth century science. According to the Royal Societys 1. Report on Krakatoas eruption, The marked linear arrangement in this immense chain of volcanic mountains across Java and Sumatra points to the existence of a great fissure in the earths crust, along which the subterranean energy has been manifested Symons 4. At the Straight of Sunda, a second fissure crosses it almost at a right angle Symons 4, and Krakatoa lies at the point of intersection of these two great lines of volcanic fissure Symons 5 see Fig. Figure 1 Map from the Royal Society Report, labeled Sketch map of the Sunda Strait, showing the lines of volcanic fissure which appear to traverse the district Symons 4Modern geology affirms this general idea, but offers a more specific explanation for the convergence of volcanic activity. In an ocean trench near Sumatra and Java, two tectonic plates collide in what is called a subduction zone, and the Indo Australian plate is forced under the Asian plate into the molten mantle below Thornton 4. As the Indo Australian plate slides downward, some of it melts, and the range of volcanoes results from this molten magma occasionally rising to the earths surface and erupting Thornton 4. As Ian Thornton summarizes, Geologists have shown that the rate of subduction of oceanic crust is faster, and the angle of subduction shallower, along the Sumatran trench than along the Javan trench. The change is abrupt and occurs at Sunda Strait 4. Sumatra has slowly rotated twenty degrees clockwise in relation to Java over the past two million years Thornton 4. Krakatoas unique position as a center of volcanic and tectonic activity is now well understood, but several other aspects of the 1. Explanations for the cause of the third great explosion and the accompanying tsunami generally fall into two competing camps, with some arguing for an upward explosion as seawater reacted with hot magma, and others for the downward collapse of the volcanos walls. Simkin and Fiske consider the debate settled Verbeek, the Dutch Mining engineer studying Krakatau immediately after the eruption, correctly deduced that the missing portion of the island had collapsed into the circular void left by the eruption of huge volumes of pumice. Alternative explanations, such as the forceful blasting out of the missing portion of Krakatau, have not been supported, and Krakatau remains a type example of caldera collapse 1. Thornton, however, thinks these key questions remain unresolved and suggests that it is likely that during the course of so complex an eruption many events cited as evidence for the competing theories occurred 3. Scientists also continue to scrutinize Krakatoa as a case study in the formation and development of an island ecosystem. Much of the attraction stems from Krakatoas likely status as an ecological tabula rasa in the immediate aftermath of the 1. Subsequent volcanic activity at Krakatoa has provided an even clearer example of an island completely devoid of life progressing toward a complex ecosystem. On 2. 6 January 2.
