The Pacific Ring of Fire has always been the subject of immense concern when it comes to earthquakes and recent activity has sparked fears of the “big one” or a massive earthquake within the area.
Quakes have rocked Japan, Guam, and Taiwan and researchers in California are saying that aftershocks can happen, which will produce cluster of tremors on the margins of the area where the quakes have taken place.
The past few weeks have seen earthquakes occurring the Ring of Fire, a horseshoe-shaped geological disaster zone.
They also spoke about the possibility of a massive earthquake happening, the “big one” in the immediate area.
The study, which was published in the Science Advances journal, analyzed 101 major earthquakes between 1990 and 2016 that happened around the Pacific Ring of Fire.
Thorne Lay, professor of Earth and planetary sciences at UC Santa Cruz, told MailOnline:
“This intuition has been challenged by statistical treatments of seismic data that indicate that, based on the clustering of earthquakes in space and time, the area that has just slipped is actually more likely to have another failure.”
“The truth appears to be more nuanced.”
“Yes, the area that slipped a lot is unlikely to slip again, as the residual stress on the fault has been lowered to well below the failure level, but the surrounding areas have been pushed toward failure in many cases, giving rise to aftershocks and the possibility of an adjacent large rupture sooner rather than later.”
“It is possible (has been observed) that dynamic stresses from large earthquake can trigger relatively widespread earthquake activation clustered in time.”
A 6.4 magnitude earthquake shook Taiwan, leaving 17 dead and at least 180 injured.
“Seismologists look for effects of such long-range earthquake interactions regularly now.”
“Taiwan, Guam and Japan are far apart relative to the static stress interactions, but one could examine the seismic shaking from an earlier event in the region of a later event to see if small earthquakes were triggered as the seismic waves went by which could have led to a cascade of failures culminating in a larger event.”
“Until that type of analysis is done, causal connection between the events is very speculative.”
“Earthquakes are happening frequently in the Ring of Fire, and some apparent space-time clustering could arise from purely random (non-interacting) activity.”
“The most “predictable” earthquakes are nearby aftershocks; after a large event, seismologists have decent statistical models that indicate how many and what size aftershocks are likely to occur for space-time windows around the source.”
“But, the models are not sophisticated enough to tell us whether one of those aftershocks will be “unusually” big, giving a second large event comparable to or larger than the first.”
Lay and the other seismologists used advanced slip-imaging methods applied to recent earthquakes which have a magnitude 7 or greater. They discovered that most aftershocks happen on the margins of the area that slipped in the main earthquake.
This is how earthquakes happen.
“This produces a halo of aftershocks surrounding the rupture and indicates that the large-slip zone is not likely to have immediate rerupture,” Lay said.
The study also suggests that a large earthquake can take place in the vicinity if there are unusually intense aftershocks that happened.
Recently, a 6.4 scale quake happened on the east coast of Taiwan. In Guam, a series of tremors happened with magnitudes 5.7, 5.6, 5.4 and 4.9. Three earthquakes shook Japan since February 11, with 4.8 and 4.5 magnitudes.
But such activities within the Pacific Ring of Fire is normal, according to scientists. Toshiyasu Nagao, head of Tokyo-based Tokai University’s Earthquake Prediction Research Centre, said that “The Pacific Rim is in a period of activity.”
Meanwhile, Dr Janine Krippner, a volcanologist at Concord University in Athens, West Virginia, said:
“In terms of volcanic history, however, the current activity is still regarded as normal.”
“It’s not referred to as the “ring of fire” because it sits there doing nothing … it is normal to have so much activity.”
In January, at least four natural disasters have occurred in the Pacific Rim. Alaska was hit by a 7.9 magnitude earthquake. Indonesia had a 6.4 quake. Mount Kusatsu-Shirane in Japan erupted.
In the Philippines, Mount Mayon spewed lava 600 metres (1,970 ft) into the air, making thousands of people evacuate.
There are some researches who do not agree that these events were related.
Professor Chris Elders, a geologist at Curtin University in Perth, Australia, commented:
“There’s not really likely to be any connection.”
“While they do indeed have the same origin – the Ring of Fire – these recent events are a coincidence.”
“The region itself is a breeding ground for seismic activity.”
Russia’s Psychic Cat Achilles Correctly Predicts World Cup Opening Game Winner
But can he predict the 2018 FIFA World Cup champion?
The new Nostradamus might be an adorable furry critter. A sweet Russian cat has been chosen to predict the outcome of the first game of the 2018 FIFA World Cup. It may seem hard to believe but the feline was spot on with his prediction.
Achilles is already a modern day prophet. After all, the cat correctly predicted most of the results in last year's Confederate Cup in Russia. Nevertheless, people wondered if the adorable feline will manage to prophesy what would happen in this year's World Cup opening game. Achilles had to choose between Russia and Saudi Arabia, and managed to predict the motherland's stunning victory....
Dog Interrupts MLB Baseball Game, Gets Rewarded With A Ball And A New Friend
The pooch thought the baseball team was trying to play fetch with her!
One lucky dog had a truly awesome day at the park. A young German Shepherd got to watch a Minor League Baseball game with her owner. In addition to that, the pooch got to play a game of fetch and made a new friend. She also went home with a ball and won the hearts of many fans.
The MLB team Tulsa Drillers recently had a Bark at the Park Night when they went up against the Northwest Arkansas Naturals. The event allows fans to bring their dogs to the field while the NWA infielders were warming up. One pooch noticed that the players were throwing a ball around. The excited German Shepherd immediately broke away from her owner and dashed to join the baseball players....
Artist Shares Emotional Comic About Finding Your Childhood Bully After Many Years
This is how bullying can haunt your life for years and years to come…
If you’ve ever been bullied as a child, you know the effects can stay with you for a long time. Harsh words and deeds can really scar the soul and there’s always the possibility that you’ll never forget the bad experience way into your adult years.
This is exactly what Meghan Lands has been through and she accurately captured how it feels like in a short comic. Now an artist, Meghan has “spent the last 20 years trying to forget her first 10.”
Despite that, the Canada-based illustrator recently took the time to look for her bully on Facebook and it made her realize and remember many things. Needless to say, it has been an emotional rollercoaster for her....
