M4.1 Earthquake 15 km ESE of Naalehu, Hawaii — June 14, 2024
2024-06-14 23:43:10 UTC (2024-06-14) · approx. 1:43 PM UTC-10 local
Felt by 67 people across nearby locations. Aftershock of the M5.2 mainshock.
On June 14, 2024 at 23:43 UTC, a magnitude 4.1 shallow crustal earthquake struck 15 km ESE of Naalehu, Hawaii, at a depth of 36.5 km and coordinates 19.0228°, -155.4385°. The earthquake was reported felt by 67 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.4 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 61 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 279, placing it among routine seismic activity. The nearest populated place is Hawaiian Ocean View (population 4,437).
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 19 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 381 m — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.2 mainshock that occurred 20 hours ago 42 km ESE of Naalehu, Hawaii. Since the mainshock, the USGS has recorded 22 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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 4.1 earthquake near Naalehu, Hawaii?
The magnitude 4.1 earthquake that struck 15 km ESE of Naalehu, Hawaii on June 14, 2024 at 23:43 UTC had a depth of 36.5 km. It was felt by 67 people with maximum shaking intensity of MMI 3.4 (light). For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 19.0228°, -155.4385°, which is 15 km ESE of Naalehu, Hawaii. The nearest populated place is Hawaiian Ocean View (population 4,437). View all earthquakes in Hawaii.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.1 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.1 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 42 km ESE of Naalehu, Hawaii. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 4.1 event is significantly smaller than that historical record.
