Citizen seismology helps decipher the 2021 Haiti earthquake

E. Calais et al.

Summary: On August 14, 2021, a 7.2 magnitude Nippes earthquake occurred in Haiti within the same fault zone as the devastating 7.0 magnitude earthquake in 2010. However, field access was limited during the event and conventional seismometers were inoperative. Citizen seismometers installed in 2019 provided critical near-field data to quickly understand the mainshock mechanism and monitor aftershocks. Machine learning applied to data from the closest citizen seismometer allowed accurate forecasting of aftershocks, demonstrating the utility of citizen science in understanding major earthquakes.

A Probabilistic Framework for Modeling the Detection Capability of Smartphone Networks in Earthquake Early Warning

Francesco Finazzi et al.

Summary: This article introduces a probabilistic framework for modeling the interaction between smartphone networks and seismic events to assess detection capabilities. The analysis showed that the detection probability of an earthquake is greatly affected by network geometry and population spatial distribution.
