M3.5 Earthquake 6 km S of Volcano, Hawaii — September 4, 2024
2024-09-04 16:53:44 UTC (2024-09-04) · approx. 6:53 AM UTC-10 local
Felt by 19 people across nearby locations. Maximum shaking intensity MMI 4.0 (moderate).
On September 4, 2024 at 16:53 UTC, a magnitude 3.5 shallow crustal earthquake struck 6 km S of Volcano, Hawaii, at a depth of 1.9 km and coordinates 19.3822°, -155.2383°. The earthquake was reported felt by 19 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.0 (moderate). This earthquake was detected by 56 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 192, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 149 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Hawaii, a region characterized by intraplate volcanic activity over the Hawaiian mantle plume hotspot, with seismicity driven by magma intrusion and flank instability. View all earthquakes in Hawaii.

Common Questions
How strong was the magnitude 3.5 earthquake near Volcano, Hawaii?
The magnitude 3.5 earthquake that struck 6 km S of Volcano, Hawaii on September 4, 2024 at 16:53 UTC had a depth of 1.9 km. It was felt by 19 people with maximum shaking intensity of MMI 4.0 (moderate). For context, this was a minor earthquake typically detected only by instruments.
Where did the earthquake occur?
The earthquake epicenter was located at 19.3822°, -155.2383°, which is 6 km S of Volcano, Hawaii. View all earthquakes in Hawaii.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.5 earthquakes can continue for several days and gradually diminish over time.
Has Hawaii had earthquakes this big before?
The largest recorded earthquake in Hawaii was the M7.9 Ka'u District earthquake of April 2, 1868. Today's magnitude 3.5 event is significantly smaller than that historical record.
