history of seismology

Seismometer
Luigi Palmieri created the first electric seismometer that could record the time of an earthquake. -
Mallet's Theory's
The Irish scientist and engineer; Robert Mallet went to Naples after a incredibly strong earthquake devastated the land to research earthquakes. His research provided us with many early theories about seismology, such as the idea that earthquakes move outward from a central focus point, and that by finding out which direction the earthquake came from, then the focal points could be located.- links for references: https://en.wikipedia.org/wiki/Robert_Mallet

The First True Seismograph
Italian physicist Filippo Cecchi created the first seismograph that detected and recorded earthquakes. -
Mercalli Intensity Scale
was a seismologist who created a scale that could measure the intensity of an earthquake, as well as the damage done by it.- links to references https://en.wikipedia.org/wiki/Giuseppe_Mercalli

The Moho Boundary
The boundary between the crust and the mantle is the Moho boundary. Seismic waves change velocity at that depth. -
The Richter Scale was created
The Richter scale was created by Charles Francis Richter and measures the strength and magnitude of earthquakes using numerical values.- links to references: https://en.wikipedia.org/wiki/Richter_scale
