Explained: Why Tonga volcano eruption was so big and what’s next

People around the world watched in awe at satellite images of spectacular underwater volcanoes erupting in giant mushroom clouds in the Pacific Ocean. Many wondered why the explosion was so large, how the resulting tsunami traveled so far, and what happened next. Shane Cronin, a New Zealand scientist and professor of volcanology at the University of Auckland, and Emily Lane, a tsunami expert at the National Institute of Water and Atmospheric Research, helped explain. explosive but brief

Saturday’s eruption was incredibly explosive, but also relatively short-lived. The plume rose more than 30 kilometers (19 miles) into the air, but the eruption only lasted about 10 minutes, unlike some larger eruptions that can last for hours. Cronin said Hunga Tonga’s Hungaha Apai eruption was one of the largest in the world in the past 30 years, with heights of ash, steam and gas comparable to the 1991 eruption of Mount Pinatubo. Philippines, killing hundreds.

Why is it so big?

The magma inside the volcano is under enormous pressure and contains gas. Cracks in the rock can cause a sudden drop in pressure that expands the gas and blasts the magma. Cronin said the crater is located about 200 meters (650 feet) below the surface of the sea, a kind of Goldilocks depth for a big bang, where sea water pours into the volcano and turns into steam immediately, adding to the explosion’s rapid expansion and energy. Anything Both deeper and extra water pressure will help control the eruption. Farflung Tsunami

To the surprise of many scientists, a single eruption could have produced a Pacific tsunami of about 1 meter (3 feet) that destroyed ships in New Zealand and caused an oil spill and two drownings in Peru. Oceanwide tsunamis are typically triggered by earthquakes that span large areas, rather than a single volcano, essentially a small point in the ocean, Lane said. She said there may be other factors at play, such as the collapse of the volcano’s underwater flank and displacing water. One interesting theory, she said, is that a shock wave, or sonic boom, from the volcano, which circled the world twice, may have injected more energy into the tsunami wave.

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine

Taking regular breaks from intense training, like deload weeks, helps your body recover, preventing fatigue and injury, and ultimately boosts fitness gains.

When it comes to getting fit, the idea of spending hours at the gym might come to mind, but many fitness experts argue that taking a “deload week” every six to eight weeks is actually key to improving your fitness gains. A deload week involves reducing the intensity of workouts to allow the body to recover from the fatigue and muscle damage caused by intense training.

While high-intensity training helps build strength and fitness, it can also lead to muscle strain, and without adequate recovery, these gains can’t fully materialise. Deload weeks give the body much-needed rest to repair and rebuild, ensuring continued progress. (Also read: Bhagyashree swears by this super easy exercise for instant leg pain relief and better mobility.

Why recovery is key for muscle growth

According to an article by The Conversation, intense exercise can cause tiny tears in muscle fibres, leading to inflammation that requires rest or low-intensity exercise to heal. This inflammation is essential for muscle growth and fitness improvements. However, without proper recovery, muscles remain in a state of slight damage, preventing inflammation from resolving. This chronic state of inflammation can hinder muscle function, reducing oxygen efficiency and impairing performance. Giving muscles time to recover through rest ensures they repair properly and are primed for continued progress, setting us up for greater success in our fitness journey.

Many gymgoers fear taking time off and are worried it will lead to a loss of gains. However, research shows that muscle genes have a “memory imprint,” which keeps them in a semi-prepared state. This allows muscles to respond more quickly and effectively to future training, promoting growth after a rest period. Even after extended periods of reduced intensity, up to seven weeks, muscular fitness can be restored to prime condition—and in some cases, surpass previous levels. Interestingly, recovery can occur twice as fast as it took to reach peak fitness initially, even if some strength is lost.

Taking time off from intense training is crucial to prevent muscle soreness and avoid overtraining syndrome. Overtraining occurs when the body doesn’t get enough rest, leading to prolonged fatigue, decreased performance, and mood disturbances. Symptoms develop gradually, making overtraining difficult to recognize until it’s severe. Rest is essential to avoid these issues and ensure long-term progress in training.

Role of overtraining syndrome and deload weeks

Overtraining syndrome is challenging to quantify due to its vague symptoms. Studies suggest it may affect as few as 10% of elite athletes, though rates could climb to 60% among highly competitive individuals. Recovery is essential for both fitness and overall health. When engaging in heavy gym routines, it’s vital to incorporate sufficient recovery time into your workout plan. Unlike rest days, which involve little to no exercise once or twice a week, deload weeks feature lighter training at reduced intensity—typically about 50% fewer workouts or a 20% drop in workout intensity.

Both rest days and deload weeks are essential for recovery and crucial to improving fitness. It’s not about choosing one over the other—they complement each other. For instance, intense training for marathons, Ironman, or CrossFit competitions requires weekly rest days alongside scheduled deload weeks. However, for recreational gym-goers exercising 1–3 times weekly at a moderate intensity, the recovery from this routine is often sufficient without the need for additional deload weeks.

Fitness influencers recommend incorporating deload weeks into training schedules every 4–8 weeks, aligning closely with the expert advice of 4–6 weeks. However, it’s crucial to listen to your body and schedule deload weeks as needed. If your performance plateaus or worsens, it may signal time for a deload. Training plans should be flexible enough to allow rest when required. Deload weeks not only enhance performance but also support overall health.
