Week 3: Earthquake Precautions & Seismicity

Portugal, among other countries, are using geographic information systems, technical models, and satellite data time series to prepare for potential risks related to climate change. Portugal's seismicity is depending on where you are located in the region. The seismicity of the Portuguese territory increases in intensity from north to south, with a spatial distribution concentrated in the south and its adjacent Atlantic margins. The seismicity in the adjacent Atlantic region is very intense as a consequence of the proximity of the boundary between the African and Eurasian plates. I found that Portugal has frequent small earthquakes, but have experienced one catastrophe. The 1755 Lisbon earthquake, also known as the Great Lisbon earthquake, occurred in Portugal on November 1, 1755. In combination with subsequent fires and a tsunami, the earthquake almost totally destroyed Lisbon and adjoining areas. Seismologists today estimate the Lisbon earthquake had a magnitude in the range of 8.5-9.0. This catastrophe was responsible for the lives of as many as 50,000 people.
