Founded first of all as an astronomical observatory in 1751 it gradually specialized also in meteorological observation starting in 1802 and that of instrumental s...

... component instrument. The triaxial system (two horizontal seismographs and one vertical) would have been provided with mag- netic damping in comparison with the previous not damped ones; so there would be increases in periods of masses oscillation cutting down the weight. The two horizontal components would have been separated from each other ( fig. 7). The wait was rather long because of or- ganizational problems inherent in the construc- tion of the microseismograph. The instrument with vertical pendulum mass was fitted with a mercury thermal compensator that made up for the variations in temperature of the metallic arm. The job was commissioned from Ferro's scientific shops of ...

A seismic event is represented by a point in a parameter space, quantified by the vector of parameter values. Studies of earthquake clustering involve considering distances between such points in multidimensional spaces. However, the metrics of earthquake parameters are different, hence the metric in a multidimensional parameter space cannot be rea...
The broader area of Western Greece is characterized by the highest rates of seismicity of the Hellenic peninsula, since it is dominated by complex tectonic structures which result in intense deformation. The northern part of this area is dominated by a continental collision zone, while the southern is characterized by the subduction zone, where the...
The speed at which an earthquake rupture propagates affects its energy balance and ground shaking impact. Dynamic models of supershear earthquakes, which are faster than the speed of shear waves, often start at subshear speed and later run faster than Eshelby’s speed. Here we present robust evidence of an early and persistent supershear rupture at...
We analyse sequences of repeating microearthquakes that were identified
by applying waveform coherency methods to data from the Parkfield
High-Resolution Seismic Network. Because by definition all events in a
sequence have similar magnitudes and locations, the temporal behaviour
of these sequences is naturally isolated, which, coupled with the high...
Hardware installation and performance tests were carried out to prepare the infrastructure for a database of seismic wave- forms. Digital seismic traces are transmitted in real-time through a satellite connection from a network of short-period stations, HiNet, operated by the National Research Institute for Earth Science and Disaster Prevention.

We also present some of the contents of the scientific correspondence studied in the course of those projects. As many scholars and observatories, above all in the 19th century, operated in different sectors of the earth sciences at the same time, we highlight the importance of a coordinated collaboration between scholars and relevant institutions and in valorising the epistolary assets produced by the earth sciences observation networks.
