Geologists: Weren’t ready for volcanoes

Humans have marveled at the awesome power of volcanoes for years and years. Earlier this month, tourists flocked to Iceland to see lava flowing from the fissure eruption on the Reykjanes peninsula. The so-called land of fire and ice saw an enormous burst in tourism following eruption of Eyjafjallajkull in 2010.

Despite their magnetic-like pull, volcanic eruptions certainly are a big threat to humanity. A report released yesterday in Nature from the University of Cambridges Centre for the analysis of Existential Risk (CSER) and the University of Birmingham discovered that there’s a general misconception of the lethal threat volcanoes pose to society and the world at large. In accordance with authors Michael Cassidy and Laura Mani, this misconception has resulted in an over-all apathy about finding your way through a significant eruption, despite it posing a larger risk than an asteroid strike.

Januarys eruption of the Hunga TongaHunga Haapai volcano in Tonga was the biggest explosion recorded by instruments. Ash was dumped over a huge selection of miles of land and sea, affecting from infrastructure to fish stocks. The eruption damaged 36.4 percent of Tongas gross domestic product, based on the World Bank. The severing of submarine cables take off the country in the southern Pacific Oceans communication with the exterior world for a complete month. It blasted enough water into fill 58,000 Olympic-sized pools in to the stratosphere and a shockwave sent tsunamis to japan and North and South American coastlines. All this devastation was due to an eruption that lasted only 11 hours. Had it gone one longer, the repercussions on the climate, food resources, along with other infrastructure could have been catastrophic.

The Tonga eruption was the volcanic exact carbon copy of an asteroid just missing the planet earth, and must be treated as a wake-up call, wrote Mani.

This threat isnt going away. The eruptions tend to be more prevalent than researchers previously believed. Recent data from ice cores (long cylinders of glacial ice uncovered by drilling right into a glacier or mountain) implies that an eruption 10 to 100 times bigger than the main one in Tonga occurs once every 625 years, or twice more frequently as have been previously thought. These events are categorized on the Volcanic Explosivity Index (VEI)that measures the explosiveness of volcanoes.

The planet hasnt seen a magnitude-7 event because the eruption of Indonesias Mount Tambora in 1815. In the archipelago, around 100,000 people lost their lives from volcanic flows, tsunamis, damage from massive rocks, ash destroying crops and homes, and extra collateral damages. Globally, temperatures dropped just as much as three degrees Fahrenheit, triggering what scientists and historians call the Year With out a Summer and major societal effects. Mass crop failures resulted in famine which resulted in uprisings and epidemics.

Based on the Centers for Disease Control and Prevention (CDC), those surviving in the facial skin of any active volcano should evacuate if told to, shelter set up by sealing all windows and doors, and maintaining a tragedy supply kit. On a far more macro level, the studys authors stress the significance of real-time targeted communication of ash fallout, gas plumes, and volcanic flows. They post that quicker messaging (preferably through texts) could better prepare communities also to assist in disaster relief.

The authors cite The Volcano Ready Communities Project in Saint Vincent and the Grenadines as a recently available success story. The project evacuated 22,000 people before an eruption in April 2021.

To best prevent more catastrophe, CSER demands increased research into volcano geoengineering, including includes the studying of countering aerosols released by way of a massive eruption. These tiny particles can filter sunlight and result in a volcanic winter. CSER also encourages more debate on whether to investigate how exactly to manipulate the pockets of magma beneath active volcanoes.

Directly affecting volcanic behavior might seem inconceivable, but so did the deflection of asteroids before formation of the NASA Planetary Defense Coordination Office in 2016, wrote Mani. The risks of an enormous eruption that devastates global society is significant. The existing underinvestment in giving an answer to this risk is merely reckless.
