A magnitude 4.7 earthquake struck near Pāpaʻikou on Hawaiʻi Island on Tuesday night, briefly shaking parts of the Big Island and surrounding islands but causing no tsunami threat or reported damage.
The quake occurred at approximately 10:37 p.m. local time, about 14 miles east of Pāpaʻikou, at a depth of roughly 24–39 km beneath the surface, according to the U.S. Geological Survey (USGS).
What happened
Residents across Hawaiʻi Island reported a short but noticeable jolt, with shaking also felt on parts of Maui, Molokaʻi, and Oʻahu. More than 700 people submitted “Did You Feel It?” reports within the first hour after the quake.
Despite the widespread feeling of the event:
- No tsunami warning or advisory was issued
- No injuries or structural damage were reported
- Emergency officials confirmed normal operations after the quake
Why the earthquake happened
Scientists with the Hawaiian Volcano Observatory explained that this quake was not related to volcanic activity. Instead, it likely resulted from tectonic stress beneath the islands.
The weight of the Hawaiian Island chain bends the Pacific Plate, creating deep earthquakes like this one within the upper mantle.
This type of seismic activity is common in Hawaiʻi and is part of the region’s normal geological behavior.
Connection to recent activity
Officials noted that this quake was similar in origin to other recent tremors in Hawaiʻi, including magnitude 4–6 earthquakes earlier in the year, but it was not directly connected to those events or to magma movement beneath the volcanoes.
Impact on residents
While no major damage occurred, many residents described:
- A sharp initial jolt followed by a brief rolling motion
- Light shaking strong enough to rattle homes and windows
- A noticeable “silence before shaking” effect in some areas, typical of nearby quakes
These experiences are consistent with moderate earthquakes at mid-depth beneath oceanic islands.
Safety outlook
Authorities emphasized that:
- Aftershocks are possible in the coming days
- No tsunami threat exists from this event
- Normal monitoring continues across Hawaiʻi seismic networks
Bottom line
The Pāpaʻikou magnitude 4.7 earthquake was a moderate, deep tectonic event caused by natural stress in the Pacific Plate. While widely felt, it was not dangerous in terms of tsunami or volcanic eruption risk, and serves as a reminder of Hawaiʻi’s ongoing seismic activity.
