Magnitude 4.4 earthquake strikes 156 km WNW of Gorontalo, Indonesia

A magnitude 4.4 earthquake struck off the coast of Indonesia today, approximately 156 kilometers west-northwest of Gorontalo. The seismic event occurred at 13:36:01.420 UTC on July 20, 2026, at a depth of 111.473 kilometers. Its epicenter was precisely located at coordinates 0.9885 latitude and 121.7341 longitude.

The U.S. Geological Survey (USGS) routinely monitors and reports on seismic activity globally, providing critical data on earthquake magnitude, location, depth, and time of occurrence. These measurements are derived from a network of seismograph stations around the world, which detect and record ground motion caused by earthquakes. The magnitude scale is a logarithmic measure indicating the energy released at the earthquake's source, often referred to as the Richter scale for older, local events, or moment magnitude for more significant global events, as reported here.
