Civil Defense says a number of agencies have no explanation for “quake” before 9 a.m.
Video by Daryl Lee PUNA, Hawaii: A noisy, unexplained shaking in the Puna area of Hawaii Island remains a mystery at this time, but it certainly has the area talking.
A number of people in a triangular area between Seaview Estates, Leilani Estates, and Black Sand Beach Subdivision report hearing a thunder-like sound, or an explosion, and feeling the ground shake around 9 a.m. on Wednesday. Folks leaving comments on the popular Punaweb forum are saying it happened around 8:42 a.m.

John Drummond, the acting administrator of the Hawaii County Civil Defense, says that the incident cannot be explained at this point in time.
Drummond says that he spoke to operators of Puna Geothermal Venture, the USGS Hawaiian Volcano Observatory, and personnel on the ground… no one has an explanation.
One theory being considered is some sort of sonic boom, although who or what could have produced such an effect is presently unknown.
News videographer Daryl Lee, who says he felt the shaking in Hawaiian Paradise Park, immediately hit the road in search of the source of the rumble. What he found were many folks around Puna makai who felt the same thing… but no answers.
I don't think it has to do with politics.

But seriously, I hope it is not going to go boom.....stay safe out there.
Santorini is essentially what remains after an enormous volcanic explosion that destroyed the earliest settlements, on a formerly single island, and created the current geological caldera.
A giant central, rectangular lagoon, which measures about 12 by 7 km (7.5 by 4.3 mi), is surrounded by 300 m (980 ft) high, steep cliffs on three sides.
The main island slopes downward to the Aegean Sea. On the fourth side, the lagoon is separated from the sea by another much smaller island called Therasia; the lagoon is connected to the sea in two places, in the northwest and southwest.
The caldera being 400m deep makes it impossible for all but the largest ships to anchor anywhere in the protected bay; there is, however, a newly built marina in Vlychada on the southwestern coast. The principal port is called Athinias. The capital, Fira, clings to the top of the cliff looking down on the lagoon. The volcanic rocks present from the prior eruptions feature olivine and have a notably small presence of hornblende.

It's that normal?
this action shot was just taken the other day by a friend, of lava entering the ocean surf!
Volcanoes are unpredictable.
Yes it is very normal. The Hawaiian islands are constantly growing. Soon there will be another fresher, newer island added. It's happening right now.
Kilauea is currently in a lava flow mode, as it has been for the other 40 percent of the past 2,500 years. During these quieter periods, the volcano begins to rebuild itself by piling lava flow on top of lava flow.
Kilauea, however, could switch back to an explosive period without much warning, Swanson said, because scientists don't fully understand how these explosions begin.
These powerful and dangerous volcanic periods can last hundreds of years. "We don't know when the next period of explosive activity may start," Swanson said. "Is it a threat today? Ithink the answer is clearly yes," Swanson said. Whenever Kilauea returns to an explosive mode, a long-term evacuation of the summit, a popular vacation spot, will be necessary.
Thanks for the info, it's good to know.

i did feel that fast blast of an earthquake the other day myself, but no associated sounds as i live pretty far from the active part of the island, but i did see a friend of mine make a fb post on how weird she thought this fast quake was and she did comment on a sound like a freight train..
