A Report of the Observed Intensity and Structural Damage during the Mw 5.3 Earthquake in Santo Domingo (Province of Chiriquí, Panamá) on 8 July 2024
<p>Shakemap from the earthquake that occurred on 8 July 2024, by the Earthquake Engineering Laboratory. The event was identified as a local strike-slip fault, associated with the series of faults crossing the Gulf of Chiriquí, with a moment magnitude of 5.3. Scale is based on Worden et al. [<a href="#B20-geosciences-14-00216" class="html-bibr">20</a>].</p> "> Figure 2
<p>The attenuation of peak ground acceleration as a function of epicentral distance recorded at 95 stations from the Panama Accelerographic Network and the Costa Rican Strong Motion Network. CHUS refers to the seismic station located in David, Chiriquí, Panama.</p> "> Figure 3
<p>Accelerograms recorded at CHUS. The signals were baseline-corrected and filtered using a fourth-order Butterworth bandpass filter with a frequency range of 0.10 to 25 Hz.</p> "> Figure 4

<p>Comparison of the 5% damped response spectra estimated with RotD100 (rotated component of ground motion spectra that envelope all possible orientations), horizontal acceleration components (N-S and E-W), and rotated components (° rot) from the 8 July 2024 Mw 5.3 Santo Domingo earthquake recorded at CHUS.</p> "> Figure 6
<p>A comparison of the response spectra of records at CHUS during the 2024 Santo Domingo earthquake with those suggested in the Panama structural regulations (REP) for David (Chiriquí) in the 2004 (green line) and 2021 versions (red and blue lines). For 2021, the spectra corresponding to uniform seismic hazards with return periods of 2500 (red line) and 475 years (blue line), respectively, are shown. These spectra were developed for Site B (rock—amplification factor of 1) and an importance coefficient of 1.</p> "> Figure 7
