I am totally astounded by what I read when I compare these two texts: Maria Graham's description of the coastal #uplift due to the 1822 #Valparaiso #earthquake, versus Charles Darwin's text on very similar phenomena related to the 1835 #Concepción earthquake.

Read carefully, paying attention to the expressions used. It's like if #Darwin borrowed Maria Graham's words, but also her interpretation about the accumulation of earthquakes raising the coast on the long term. 🤔
Any comment ?

Both 1822 and 1835 earthquakes happened in Central #Chile on the #subduction #megathrust between Nazca and South America #tectonic_plates. Darwin's description, based on Fitz Roy (Beagle's captain) observations, is considered as seminal.

Thanks @haq for pointing me to the work by Maria Graham.

El #9dic de 1758 nace en Caracas María de la Concepción Palacios y Blanco, madre de Simón Bolívar. A los quince años de edad casó con Juan Vicente Bolívar y Ponte. Los Palacios siempre fueron gente de buen gusto. A doña María de la Concepción le apasionaba la música, tocaba la flauta con delicadeza, sobre todo en las veladas familiares. Murió muy joven, a los 34 años de edad, dejando huérfanos a María Antonia, Juana, Juan Vicente y Simón Bolívar.
