Ml 3.0 Vetto (Reggio Emilia)

An earthquake of Ml 3.0 at a depth of 24 km occurred in Vetto (Reggio Emilia, Italy) on 10 April 2024 at 04:20:48 UTC (data from INGV).

The Modena station on the AM.R7231 seismograph, clearly captured the earthquake mostly in its EHZ, EHN and EHE displacement components, where the seismograms shows the seismic phases P, S. The seismic signal was band-pass filtered 3.0-8.0 Hz and pole 2.

The EHE component of AM.R7231 with seismic phases picking.

From AM.R7231 difference of S-P phases is about 7.73s for a distance to epicenter of 0.375° (41.7 km). The origin time is T0 = 04:20:48.9 UTC. This value is comparable with the value calculated by INGV.

The 0Pmax along EHE is 941.1 nm for a Ml 3.0; This value is comparable with the value calculated by INGV. 

The EHE component of DOL.MDN01 with seismic phases picking.

From DOL.MDN01 difference of S-P phases is about 7.75s for a distance to epicenter of 0.375° (41.7 km). The origin time is T0 = 04:20:48.5 UTC. This value is comparable with the value calculated by INGV.

The magnitude cannot be calculated, due to not-calibration of the Ml calculation formula.
