[1] For a biography of Mallet and a detailed account of his 1858 research trip to Italy see Graziano Ferrari and Anita McConnell, ‘Robert Mallet and the ‘Great Neapolitan Earthquake of 1857’, Notes and Records of the Royal Society, January 2005 vol. In October 1849, aged 39, Robert, and his son John, who was a chemistry student at TCD, decided to carry out a remarkable experiment on Killiney Beach. The science of seismology, which studies the power and energy unleashed by earthquakes, began life on a south Dublin beach in 1849 with an ingenious experiment carried out by one of Ireland’s greatest scientists. El 16 de diciembre de 1857, el área alrededor de Padula (Italia) fue devastada por el gran terremoto de Nápoles, que causó 11.000 muertes. Mallet travelled to the Italian peninsula at a time of social and political upheaval. Change ), You are commenting using your Twitter account. The most striking example of the latter point is Mallet’s account of the town of Polla in Campania: Months of bombardment would not have produced the destruction, that the awful shudder of five seconds involved, when thirteen hundred houses fell together with deafening crash, and overwhelmed the two thousand of their sleeping inmates, and with clouds of suffocating dust, choked the cries of horror and anguish, that rose from the startled and often wounded survivors. Among his scientific papers are investigations of the “seed-dispersing apparatus” of Erodium moschatum (1836); the blackening of photographic paper due to the radiation of glowing cinders (1837); the photochemical bleaching of caustic potash; the effect of boiling on organic and inorganic substances (1838); the improvement of the manufacture of optical glasses; and the application of the “electrotype process in conducting organic analysis” (1843).
Robert Mallet, an engineer born in Dublin who designed many of London's bridges, measured the velocity of seismic waves in the earth using explosions of gunpowder. His name is associated with the “buckled plates,” which he patented in 1852, used for flooring and later for railroad ties. 10 March 1908) This enabled the Emperor to quickly dispatch help to the afflicted area. By the first week of January 1858 he had secured research funding from the Geological Society of London as well as Dublin’s Royal Geological Society. Mallet considered local elevations of portions of the earth’s solid crust to be the cause of earthquakes.

In three different directions, conflagration soon added its terrors to the scene, and beamed up, a flickering and ominous light, into that dreadful night of cold and wailing, throughout the lingering hours of which, in helpless agony, they listened to the passionate entreaties for relief, the dying sobs, of relatives and friends entombed around them, and dreaded for them, more than for themselves, the recurrence of other shocks. El 9 de febrero de 1846, Mallet presentó a la Real Academia Irlandesa su artículo sobre "La Dinámica de los Terremotos", considerado como una de las bases fundacionales de la sismología moderna. Another son died…, Strutt, John William, Third Baron Rayleigh . 33 (Spring, 1992), pp.
The Piedmontese Moderates who oversaw the establishment of the fledgling Italian state reacted to brigand violence and civil unrest with brutally repressive measures. The term “seismology” we owe to Mallet, as well as “seismic focus,” “angle of emergence,” “isoseismal line,” and “meizoseismal area,”. His multifarious engineering projects also involved work on steam-driven printing plants, bridges, hydraulic presses, ventilators and heaters, brewery machinery, railroads, dock gates, viaducts, lighthouses, and coal mines. William had suggested to Robert that he might apply the laws of physics, as they apply to light, in order to describe how the energy generated by the explosion would pass through sand and rock (for the rock measurements he set up a seismoscope on nearby rocky Dalkey Island, rather than the sandy beach). . A list of eighty-five (incorrectly numbered ninety-one) papers by Mallet is in Royal Society Catalogue of Scientific papers, IV.
At the ripe old age of 22 he was elected to the Royal Irish Academy and on February 9th 1846 he presented his paper to the Academy ‘On the Dynamics of Earthquakes’, which is considered to be one of the foundation papers of modern seismology.

Con ocasión de la Guerra de Crimea, diseñó un mortero pesado (de 43 toneladas de peso y 910 mm calibre) capaz de lanzar balas esféricas de 1100 kg a una distancia de 2,4 km. They wanted to prove that energy moved through sand and rock in waves that could be measured, and they designed a ‘controlled’ experiment to prove this was so.
