“Terremoto” o que é Magnitude e Escala Richter. A escala de Richter foi desenvolvida em 1935 pelos sismólogos Charles Francis Richter e Beno Gutenberg, ambos membros do California Institute of Technology (Caltech), que estudavam sismos no sul da Califórnia, utilizando um equipamento específico – o sismógrafo Wood-Anderson. Após recolher dados de inúmeras ondas sísmicas liberadas por terremotos, criaram um sistema para calcular as magnitudes dessas ondas. A história não conservou o nome de Beno Gutenberg. No princípio, esta escala estava destinada a medir unicamente os tremores que se produziram na Califórnia (oeste dos Estados Unidos). Apesar do surgimento de vários outros tipos de escalas para medir terremotos, a escala Richter continua sendo largamente utilizada. Princípio: É uma escala logarítmica: a magnitude de Richter corresponde ao logaritmo da medida da amplitude das ondas sísmicas de tipo P e S a 100 km do epicentro. A fórmula utilizada é: ML = logA – logA0, onde A representa a amplitude máxima medida no sismógrafo e A0 representa uma amplitude de referência. Assim, por exemplo, um sismo com magnitude 6 tem uma amplitude 10 vezes maior que um sismo de magnitude 5. Porém, o sismo de magnitude 6 liberta cerca de 31 vezes mais energia que o de magnitude 5.
