Officials Panic As Mount St. Helens Volcano Scientists Detected 250% Increase In Eruption Activity

Mount St Helen that Mount St Helens Mount St Helens Mount St Helens so when Mount St Helens woke up in the spring of 1980 uh it was too good to be true I could hardly believe that it was really [Music] happening Mount St Helens seems to be stirring awake again with the US Geological Survey USGS noting a recent uptick in seismic activity in just the past week 15 earthquakes were recorded contributing to a total of 498 since February 1st the biggest Quake last week hit a magnitude of 0.6 while the most significant since February reached 2.0 curiously these Tremors occurred at an average depth of 2.7 Mi beneath the crater a bit shallower than the previous average of 3.9 Mi horrifying isn't it since July 15 2023 over 400 Quakes have rattled the region what could this mean for the future of Mount St Helens with no changes detected in ground deformation or gas emissions should we be concerned or is this simply Nature's Way of reminding us of its power future cracks what lies ahead from Mount St Helen's research has indicated that short-term earthquake activity is typical at Mount St Helen and is part of its normal behavior notably the recent surge in seismicity is the most significant increase since the last eruption ended in 2008 however even larger earthquake sequences in the late 80s and 90s didn't lead to eruptions these small Quakes occurring deep within the volcano are often associated with the pressurization of the magma transport system this phenomenon known as recharge involves fresh magma entering the upper Reservoir creating stress and triggering earthquakes that can last for years without resulting in an eruption Mount St Helens a tanic Awakening in 1980 on March 27th 1980 Mount St Helens in Washington state erupted kicking off a series of explosive volcanic events that would lead to one of the US deadliest eruptions the peak explosion occurred on May 18th at 8:32 a.m. registering a volcanic explosivity index of five marking the most significant eruption since lass and peak in 1915 this disastrous event followed 2 months of seismic activity and and steam eruptions caused by magma buildup leading to a devastating Landslide and explosive blast the eruption generated an ash plume reaching 880,000 ft impacting 11 states and parts of Canada and resulting in 57 fatalities including notable individuals with over $1 billion dollar in Damages it reshaped the region and created the Mount St Helen's National volcanic Monument serving as a reminder of Nature's formidable power beneath the surface the volcanic tension Rising after being dormant since the 1840s Mount St Helens erupted with a series of earthquakes beginning March 15th 1980 culminating in a significant 4.2 magnitude Quake on March 20th this seismic activity led to the first steam driven eruption on March 27th sending Ash 7,000 ft into the air by late April the North Face had bulged dangerously prompting warnings of a potential catastrophic eruption on May 18th a magnitude 5.1 earthquake triggered the largest recorded sub aial Landslide resulting in a massive eruption that sent Ash 880,000 ft into the atmosphere devastated the surrounding area claimed 57 lives and caused over $1 billion in Damages pyroclastic flows a serious hazard in volcanic eruptions the landslide at Mount St Helens in 1980 exposed deite magma to lower pressure triggering an explosive release of gas gas and high pressure steam within seconds the northward explosion sent a pyroclastic flow of volcanic gases Ash and pmus racing down the mountain initially traveling at 220 mph the flow accelerated to 670 mph possibly surpassing the speed of sound this blast devastated an area 23 M wide and 19 M long flattening 230 s Mi of forest the superheated flow also Al flashed water into steam causing a secondary explosion heard as far as British Columbia outcome from lateral blast in the direct blast zone of Mount St Helen's trees were snapped like twigs and the Earth was stripped bare and scorched the near supersonic blast packed with volcanic debris devastated areas up to 19 Mi away the blast zone was divided into three areas the direct Blast Zone where everything was destroyed the directed Blast Zone where trees were flattened in rows like grass and the the seared Zone where trees stood but were charred tragically 57 people lost their lives many to Suffocation or burns from the intense heat later flows after the landslide fresh magmatic debris created pyroclastic flows that formed fan-like patterns during the May 18th eruption at least 17 flows occurred totaling about 0.05 cubic miles even Weeks Later deposits remained extremely hot fueling steam blast eruptions that continued for months with one recorded on May 16th 1981 the elements within exploring volcanic chemical composition the ash from Mount St Helens is composed of roughly 65% silicon dioxide 18% aluminum oxide 5% feric oxide 4% calcium oxide 4% sodium oxide and 2% magnesium oxide Trace elements include 0.05 0 0 9% chlorine 0.02 0.03% Florine and 0.09 0.3% sulfur the index of refraction of the ash which indicates how light interacts with it has a real part ranging from 1.5 to 1.6 for visible light the ash settled in three layers the bottom layer is dark gray with older rocks and crystals the middle consists of glass shards and pmus and the top layer contains very fine particles the aftermath of how mudslides transformed the landscape the eruption melted nearly all of Mount St Helen's glaciers and snow triggering massive lahars volcanic mud flows that impacted three of the mountains four stream Drainage Systems starting as early as 8:50 a.m. these mud flows race down at speeds of up to 90 mph 140 km perh before slowing to about 3 mph 4.8 km perh in wider River areas they mixed with tefra and created larger lahars flooding the toutle river and its Forks by 1: p.m. a 12T High 4 a.m. wall of Muddy Water was reported and the flow eventually added around 3, 900,000 cubic yards 3 million cubic M of debris to the Columbia River temporarily closing a busy shipping channel and costing Portland an estimated $5 million deadliest volcanic event and its outcome the May 18th 1980 eruption was the deadliest and most destructive volcanic event in the contiguous United States the blast directly killed 57 people and obliterated 200 homes 47 Bridges 15 Mi of Railways and 185 Mi of Highways additionally two individuals died invisibility related accidents and two more suffered fatal heart attacks from shoveling Ash president President Jimmy Carter who surveyed the damage remarked it resembled a moonscape over 1 cubic mile of material was ejected with a quarter being fresh lava the eruption caused extensive ecological damage killing wildlife and destroying crops while releasing energy equivalent to 1,600 hirosima bombs evaluating damage and cleanup challenge due to Ash the ash falls from the eruption caused significant disruptions in transportation SE disposal and water treatment visibility dropped leading to the closure of Highways including a week and a half closure of Interstate 90 airports in Eastern Washington also shut down cancelling over a th000 commercial flights communities fa the Monumental task of removing about 2.4 million cubic yards of Ash costing $2.2 million and taking 10 weeks in Yakama cities utilized old quaries and landfills for disposal while Portland's mayor threatened fines for businesses that neglected Ash removal from their properties consequences Mount ceste Helens had to Bear the Mount St Helens eruption caused an estimated $1.1 billion in Damages $3.4 billion today leading Congress to allocate $951 million for disaster relief mainly for the small business administration US Army Corp House of Engineers and FEMA unemployment surged tenfold but stabilized with Timber salvaging and Ash cleanup efforts while residents experienced emotional stress most remained in the area initially tourism suffered but Mount St Helens regained its appeal resulting in reopen visitor centers and heightened interest in the volcano's recovery scientists track magma recharge under St Helen's since the 1980 eruption Mount St Helens has remained active with five more explosive events in 1980 and at least 21 eruptions by early 1990 continuing until 2008 the May 25th eruption sent Ash 9 miles into the atmosphere impacting Western Washington and Oregon later eruptions in June and July reached 10 Mi High while by 1987 a new dome had grown to over 3,000 ft wide currently around 350 earthquakes since February indicate possible magma recharge though experts when this doesn't ensure an eruption the USGS closely monitors the volcano what do you think the future holds from Mount St Helens are we
