As if the house physician of Hawaii ’s Big Island do n’t have enough to worry about already , the US Geological Survey is now warning residents of yet another menace : great rocks shooting from Kilauea ’s crater . Several rock and roll , include one measuring two metrical unit wide , have already descend — but the situation could get even unfit .
It ’s been two week since Hawaii ’s Kilauea vent began erupting , and there ’s no apparent end in sight . At least 17 fissures have been record in the vent ’s East Rift Zone , and ash plumes from the crater are raising the possibility of acrid rain and volcanic smogginess , or “ vog , ” packed with noxious sulfur dioxide . The US Geological Survey ( USGS ) iswarningthat the eruption is still develop and extra outbreaks of lava are possible , along with on-going ground deformation and seism .

Earlier in the week , ash emissions from the Kilauea summitreached as high as 10,000 foot above sea story , causing headaches for both residential neighborhoods and airway . The cloud stray downwind from the volcano , dangle dust on communities from Pahala to Discovery Harbor .
On Wednesday , a 4.2 - order of magnitude seism shook the neighborhood in the early hours — and then the sky began to fall .
“ This morning dense ballistic pulley up to 60 cm ( 2 feet ) across were find in the parking lot a few hundred yards from Halemaumau , ” wrote the USGS in its advisory . “ These ruminate the most energetic explosions yet observed and could reverberate the onset of steam - drive explosive activeness . ” Halemaumau is an dynamic infernal region volcanic crater nestle within the larger summit caldera of Kilauea .

No damage or hurt have been report , but the USGS is closely monitoring the missile rock endangerment . Additional steam - driven explosions are await , and it ’s possible they could be even more potent . It ’s been nearly a century since KIlauea has hurled rocks like this , according to the USGS .
“ During steam - drive explosions , ballistic blocks up to 2 m [ 6.5 human foot ] across could be drop in all charge to a distance of 1 kilometre ( 0.6 international nautical mile ) or more . These blocks could weigh a few kg ( pound ) to several wads , ” the USGSsaid . “ small ( pebble - size of it ) rocks could be send several kilometers ( miles ) from Halemaumau , mostly in a downwind direction . ”
Since Kilauea begin flare up on May 3 , dozens of home have been destroyed , and hundreds of people have been evacuated . The lake on the summit is still inthe thick of deflating , enhance the risk of trigger-happy blowup .
