Magnitude: Earthquakes
Katapult Inc.
Earthquake information, clearly. Magnitude brings together public earthquake data from SGC and USGS. Explore recent and historical earthquakes on a map, view event details, and choose notifications by magnitude, worldwide or within a saved radius. In Colombia, optional warnings are relayed by a volunteer network. Eligible strong-shaking warnings can use Critical Alerts with your permission. Coverage and delivery vary; Magnitude does not predict earthquakes or replace official guidance. Free, with no ads or account required. Available in English and Spanish.
