How strong was this earthquake?
Micro earthquakes are almost never felt at the surface and are recorded only by seismographs.
A magnitude 1.5 earthquake radiates roughly 2.9 kg of TNT equivalent in seismic energy.
The USGS assigns this earthquake a significance score of 36, which is below the USGS threshold of more than 600 for its significant-earthquake list. The ranking combines magnitude with available Did You Feel It responses and PAGER alert level; it is not a direct measurement of damage.
Where was the epicentre?
The epicentre was located at 37.0139, -117.5430 — 63 km east-northeast of Independence. The closest other recorded event was a magnitude 1.8 earthquake 62 km north-northwest of here on 27 July 2026.
Why the 4 km depth matters
At 4 km this was a shallow earthquake. Shallow events release their energy close to the surface, so for a given magnitude they produce noticeably stronger shaking — and more damage — than deeper ones. Roughly three quarters of all earthquakes worldwide occur at shallow depths.
This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, events this small are usually detected by instruments rather than people. Its shallow focus makes stronger surface shaking more likely than for a deeper event of the same magnitude.
What does the tsunami information flag mean?
The USGS record does not carry a link to NOAA tsunami information. That field is not an all-clear and does not state whether a tsunami occurred. In this case, a damaging tsunami would be less likely because at M1.5 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; it occurred inland rather than beneath the sea floor. For an active coastal alert, use tsunami.gov or your local warning authority.

Aftershocks and local seismic history
25 further earthquakes have been recorded within about 150 km of the epicentre in the 2 days since this event, the largest of them magnitude 3.6.
12 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.8 event near Big Pine on 29 June 2025. This M1.5 event released about 83,176 times less energy than that event.
