Frame 1 -Our colleagues from the #RedSísmicaNacional have installed a seismic station in the dam of #Itoiz to monitor seismic activity in this geographic area of #Navarra .
Frame 2 -Good disclosure! For their part, dams, such as the one in Itoiz where you are, following the protocol established in their Emergency Plans, activate scenario 0 when an earthquake occurs in the environment. This entails a thorough and detailed review of the infrastructures (1/2)
Frame 3 - That increases the vigilance for security and good exploitation that it already does @CH_Ebro continuously in dams. Scenario 0 of the Emergency Plan with the mandatory inspections was activated by the recent earthquake in Itoiz, Alloz, Urdalur, Mairaga, Eugui and Yesa (2/2)

Earthquake data are not that objective: Here is an example from Denmark. Recently there was a quake on September 30th
The earthquake measured 3.4 on the local Richter scale, which is relatively large for Denmark, and it could be felt locally in Thy. It is one of the areas where earthquakes are most frequently registered in Denmark, so it is not entirely unusual for the citizens of Thy to feel tremors.
From the above page, there is this picture, where the green spot is where it happened. Btw. the geologists are not able to explain the persistent presence of the cluster in the northwest.
