More than 50 earthquakes rattle Hawaii volcano in past 24 hours, geologists say


A swarm of at least 50 small-magnitude earthquakeshas rattled the Mauna Loa volcano on the Big Island in Hawaii over the past 24 hours, the U.S. Geological Survey reported Tuesday, Nov. 15. All of the quakes were below 3.0 magnitude, geologists said. Mauna Loa is the world’s biggest active volcano. It is not erupting and there are “no signs of an imminent eruption,” according to geologists.

However, the area is in a state of “heightened unrest” due to the increased earthquake activity and “inflation of the summit,” USGS said. The activity is likely being driven by new magma entering between 2 and 5 miles below the volcano’s summit. Officials detected the earthquakes 2 to 3 miles below Mokuʻāweoweo caldera and 4 to 5 miles “beneath the upper-elevation northwest flank of Mauna Loa.” Both regions “have historically been seismically active during periods of unrest on Mauna Loa.”

thank you.... i appreciate that..... .so far we have been in no danger from mauna loa... only under advisory..... ..it;s mauna kea that puts us in the real danger whenever it erupts due to the large section of elevated coastline that could be shaken loose and slide into the ocean sending a tsunami our way....

but we don;t even feel the effects of the current mauna loa earthquakes in our building unless they get a little bigger than they are now.... people on the kailua side of the island feel tremors from them and can even hear them coming at night.... it comes like a rumble in the distance that get s louder until the house starts shaking and the dishes in their cabinets start rattling.....

here is one of the websites we keep an eye on....

Mauna Loa - Volcano Updates | U.S. Geological Survey

The Hawaiian Volcano Observatory issues updates and other types of Mauna Loa notifications as activity warrants.

www.usgs.gov

and then of course this is the website down below that would give us warning of possible tsunamis coming from other parts of the pacific.... but since the travel time of a tsunami from mauna kea to honolulu would only be 10 minutes there would not be time to look at a website if we felt a really big quake shake up oahu..... the only thing to do would be get into the jeep and drive to high ground..... i say jeep because the waves could exceed 1000 feet high and the wash up could reach 3000 feet in some areas..... .. none of the regular roads will take you high enough here to avoid waves from a major mauna kea event..... you gotta get up onto an elevated ridge or way up into the mountains where the wallabys..... native birds... and menehune hide out.....

. i say jeep because the waves could exceed 1000 feet high and the wash up could reach 3000 feet in some areas..

1,000 ft waves? Is that a typo? If not…blimey!

1,000 ft waves? Is that a typo? If not…blimey!

no typo on that one.. ... but i did give the wrong name of the more dangerous volcano.... it;s kilauea that could produce the 1000 ft tsunami... not mauna kea..... (mauna kea is the 13,000 ft mountain the telescopes and observatory is on..).. .... .kilauea is only at 4100 feet .... but the danger is that there is a huge section of the big island down slope from the volcano that already has a fracture zone across it... and geoligists say a big enough earth quake from kilauea could cause it to dislodge and slide into the ocean.... ..the tsunami it would produce would be 1000 feet high when it reached honolulu.... but it would also travel to all other parts of the pacific rim and completely wipe out some of the other smaller south pacific islands.... they have a chart that shows how tall the waves would be in places like northeastern australia... new zealand... new guinea... japan... and the west coast of both north and south american continents.... and though it would not be 1000 ft tall anymore and would be reduced in energy and size as it spread out across the pacific.... it would still cause massive damage and loss of life where ever it hit...... .....

the thing about a tsunami is that it;s not a huge visible wave travelling across the open ocean like they show in movies... .. and it;s not like the wind driven wave action which is what you see on every ocean everwhere..... . a tsunami is energy caused by sudden and violent geologic displacement... and it travels through the water the same way energy travels through a line of croquet balls when the mallets hits the first of them packed together..... ... and if the water is deep enough you won;t even see it... but ships at sea and bouys set to detect tsunamis can feel it...... and when it approaches shallow areas or dry land ithe energy first draws water back exposing the sea bed for an area far back proportional to the amount of wave energy it has.... then when it hits all that water comes rushing back in with more water being pushed forward behind it..... ... the water reacts the same way the croquet ball at the end of the line up does... in some places it would rush inland at speeds of over 200 mph..

i;m not sure that makes any sense.... that;s my own explanation of it based on all i have read and heard about them over the years... but it is accurate..... . we have had many tsunami warnings here but have only seen a few small ones since i have been here.... some of them did minor damage in certain places... but most parts of the island were unaffected.....

Very interesting. Thanks. Hopefully the big one stays in the movies.

Very interesting. Thanks. Hopefully the big one stays in the movies.

it;s happened before.... . there is evidence in the geologic record that shows ancient tsunamis here have sent waves of water into the valleys that washed them out from one side to the other.... and caused water to wash up and over the mountain tops the same way water in a bath tub splashes over the side when something... or someone... in the tub causes the water to wash back and forth...... the valleys are the main danger zones...... because they funnel the energy in the water together to a smaller area where it can build up.. ..

but the safest areas in a tsunami are actually ridges and high points of land...not adjacent to or connected to valleys... .in those places the energy in the tsunami will simply move around the high point continue on to lower ground.... provided it;s rock and solid strata under that ridge and not just loose or compacted soil..... a high ridge with unstable land beneath it might survive the first wave of a tsunami.. but a tsunami comes in in a series of waves..... . and successive waves will erode the softer land.... and it will all be washed out to sea when the water recedes.... ..most of the damage done by tsunamis is done when the water rushes back out rather than when it first comes in.....
