4.6-magnitude earthquake rattles Hawaii's Big Island
The U.S. Geological Survey reports a 4.6-magnitude earthquake has struck Hawaii's Big Island.
phys.orgI'll summarize the latest widely reported updates on the 2018 Hawaii earthquake based on recent public sources. Then I can provide more details if you want.Here are the most recent, widely reported updates about the 2018 Hawaii earthquake sequence:
- The strongest event in the May 2018 Hawaii sequence was a magnitude 6.9 earthquake on May 4, 2018, occurring on the south flank of Kilauea near the area affected by ongoing lava activity; it was the largest Hawaii earthquake since 1975.[1][2]
- The event did not generate a Pacific-wide tsunami according to the Pacific Tsunami Warning Center at the time.[1]
- The May 2018 sequence was closely linked to the Kilauea eruption activity, with aftershocks and continued seismicity in the weeks and months that followed; this included continued shaking and structural impacts in affected areas on the Big Island.[5]
- Aftershocks persisted for months, and analyses note that the May 4 magnitude-6.9 event caused measurable ground movement such as the Hilina Slump and contributed to the broader context of Hawaii’s 2018 eruptive sequence.[2][5]
If you’d like, I can pull specific details (e.g., epicenters, depths, magnitudes of aftershocks, or summaries from USGS reports) and provide a compact data-backed timeline. I can also assemble a short map or chart highlighting the major events in May 2018.
