[Ed. – Burning ring of fire. Note: a 5.4 will really wake you up, and a 6.9 is yuuge. A duration of 15 seconds is also really long. This isn’t ordinary.]
Just an hour after a large tremor Friday morning, a 6.9-magnitude earthquake shook the Big Island on Friday afternoon, sending people fleeing from buildings and community centers and increasing concerns about new eruptions in Puna’s Leilani Estates.
Bystanders said the latest quake appeared to last about 15 seconds.
It came about an hour after a 5.4 magnitude shook the Big Island Friday morning, which was followed by a fifth eruption spewing lava into Leilani Estates. …
Dramatic images from the subdivision show lava bubbling up from the ground and soaring more than 100 feet in the air.
Residents described the sound of the eruptions as haunting — “hissing” and “like a freight train.”
Active volcanic vents have been reported on Mohala Street.
