Waveform Analysis of the Magnitude 4.0 Earthquake in Iruña Oka, Álava, Vitoria
Reading time: 5 minutes

This earthquake was detected by seismic stations in neighboring countries, such as Portugal, France, the United Kingdom, Italy, and Germany.

We are sharing the earthquake waveform image, filtered between 0.5 Hz and 5 Hz, which were the frequency ranges where our alarms were triggered.

The seismic station detection software is proprietary, developed entirely by us. The sensor that detected the seismic movement is a 4.5Hz geophone operating at 200 V/m/s. The station that captured this graph is located in Girona, about 466km from the epicenter.

Populations and intensity in which the earthquake has been felt, according to IGN:
