Following an earthquake last night, a second quake struck Hawaii’s Big Island today (July 3).
The temblor occurred at 2:18 p.m. local time (5:18 p.m. B.C. time).
Although the U.S. Geological Survey reported it as a 4.1.-magnitude quake based on preliminary measurements, it was later upscaled to a 4.3-magnitude seismic event.
Slightly deeper than the previous 4.6-magnitude quake (see below), the epicentre, at a depth of seven kilometres (four miles), was in the same area as the previous quake—it was located 14 kilometres (nine miles) south of Fern Forest; 32 kilometres (20 miles) southwest of Hawaiian Paradise Park; 44 kilometres (27 miles) south of Hilo;. and 360 kilometres (224 miles) southeast of Honolulu.
The quake wasn’t strong enough to generate a tsunami so no warning was issued. However, it was reported as felt on the island of Hawai’i.
An earthquake shook the Hawaiian archipelago last night.
The quake was located near the Holei Pali escarpment of Hawai’i, or the Big Island, and struck at 11:20 p.m. local time on July 2 (2:20 a.m. on July 3 B.C. time).
The U.S. Geological Survey initially reported it as a 4.5-magnitude quake but it was later reassessed as 4.6-magnitude.
The epicentre, at a shallow depth of three kilometres (two miles), was located 15 kilometres (nine miles) south of Fern Forest; 32 kllometres (20 miles) southwest of Hawaiian Paradise Park; 45 kilometres (28 miles) south of Hilo; and 361 kilometres (224 miles) southeast of Honolulu.
Seismologists believe it to be an aftershock from a 6.9-magnitude quake in 2018 from the eruption of Kilauea volcano, which is still settling.
Although structural damage wasn’t reported, shaking was reported felt on the islands of Hawai’i, Maui, and Lana’i.
A tsunami warning was not issued.
