1810	Dublin, Ireland		Robert Mallet born. Not only was Robert Mallet the inventor of the word seismology, but he is considered the "first" seismologist. He was an engineer of considerable skill and his contributions to seismology mark the birth of the science. He constructed the first comprehensive earthquake catalog and world seismicity map. In the late 1840's Mallet used explosions to produce seismic waves and investigated the idea that seismic waves travel at different speeds in different rock types. Following the 1857 Napolean earthquake, Mallet traveled to Italy and using the orientation of cracks and fallen masonry produced an isoseismal map for the event. The map identified areas of similar intensities of shaking.
