PREDICTION

There are tens of shocks occurred in San Ramon during last two days Prediction Report ID : GUIEP-PR-2026-02-04T12:40UTC Earthquake Location : San Ramon CA Live Earthquakes : click here Statement: So far, seismic activity in this region is likely to remain active for a few more days. no earthquakes of magnitude 5 or higher are expected. And the stress adjustment rate is lower than normal. We will continue to monitor the situation and update everyone in the coming days.

Using a consistent spatial window centered on Yellowstone (44.615°N, -110.6°W; radius 80 km), we analyzed the Seismicity Index S time series from 1984-2025 at multiple magnitude thresholds and time scales (annual/monthly/weekly). S exhibits a persistent long-term increase that remains present when smaller earthquakes are excluded (M≥2.0 and M≥2.5). This indicates that the observed intensification is not solely an artifact of small-event catalog completeness. Importantly, the
