: What is the Pacific Ring of Fire and why it is prone to quakes and tsunamis
The Pacific Ring of Fire is not an official scientific term but rather a widely accepted description for a chain of active volcanoes and fault lines surrounding the Pacific Ocean. This zone covers a 40,000-kilometre horseshoe-shaped area, touching countries like Japan, Indonesia, New Zealand, the Philippines, Alaska, the US West Coast, and South America's Pacific edge.
Volcanic activity: Around 75% of Earth's active volcanoes are located here.
Earthquake frequency: Nearly 90% of the world's earthquakes occur in this seismic belt.
Its geological activity is primarily driven by subduction zones, where one tectonic plate slides beneath another, creating intense seismic stress.
Major disasters along the Pacific Ring of Fire you should know about
The Ring of Fire has been the epicenter of several historic disasters:
2011 Japan Earthquake & Fukushima Disaster: Triggered a massive tsunami and nuclear accident.
1960 Great Chilean Earthquake: The strongest earthquake ever recorded (magnitude 9.5).
2004 Indian Ocean Earthquake & Tsunami: Killed over 230,000 people across 14 countries.
1964 Alaska Earthquake: One of North America's most powerful seismic events.
These events underline the catastrophic potential of this geological zone and the urgent need for early warning systems.

Why is the Pacific Ring of Fire so active and prone to earthquakes and Tsunamis
The Pacific Plate, Earth's largest tectonic plate, is surrounded by several smaller plates. Most boundaries within the Ring of Fire are subduction zones, where plates collide and one sinks beneath the other. These movements generate:
Earthquakes: Sudden fault slips release immense energy, shaking entire regions.
Volcanic eruptions: Melting rock from subduction forms magma, fueling volcanoes.
Tsunamis: Seafloor displacement can create waves traveling across oceans in minutes.
According to Michael Blanpied of the US Geological Survey, 'The Pacific is unique in that it's completely ringed by highly active tectonic boundaries.'
Global seismic networks and records improve earthquake and Tsunami preparedness
Advances in seismic monitoring have transformed how we understand the Ring of Fire.
A global network of sensors now provides near-instant earthquake detection and tsunami alerts. Nations along the Ring of Fire share seismic data and disaster strategies to minimize damage and save lives. Anna Kaiser, a seismologist, emphasizes international cooperation: 'It's really important as scientists for us to collaborate and learn from other parts of the world and particularly around the Pacific.
'
Studying ancient earthquake and tsunami records helps scientists estimate future risks. Historical data, such as pre-1900 tsunami records in Indonesia, provide insight into the 'seismic rhythm' of faults. As historian Anthony Reid explains, understanding past seismic patterns helps predict future catastrophic events, even if precise forecasting remains elusive.

White beluga whales and their strange link with Russia's 8.8 earthquake
Natural disasters often hit the landscape without warning, leaving the affected people scrambling to respond. Yet, throughout history, there have been interesting stories of animals sensing danger before such events actually happen. Tired of too many ads? go ad free now While science is still looking for answers about such phenomena, social media has become a hub for sharing such accounts. Recently, a powerful earthquake rocked Russia, causing tsunami warnings across multiple countries. Along with this event, a viral video showing beluga whales stranded on a Kamchatka shore sparked renewed interest in the idea that animals might sense impending natural calamities. This incident has led many to question whether animals' unusual behavior could serve as early warnings, helping humans prepare for disasters. An 8.8 magnitude earthquake shakes Kamchatka The massive earthquake measuring 8.8 on the Richter scale struck Russia's Kamchatka Peninsula. The quake's epicenter was approximately 20.7 kilometers deep and about 119 kilometers from the city of Petropavlovsk-Kamchatsky, as reported by the Associated Press. Initially, the magnitude was recorded at 8.0 by agencies in Japan and the US, but the US Geological Survey later upgraded it to 8.8. This powerful tremor triggered tsunami warnings in several countries, including the United States, Japan, Chile, and New Zealand. The viral beluga whale video A video widely shared on social media shows five beluga whales, including a calf, stranded on a Kamchatka shore. The whales appeared to have ventured into shallow waters and became trapped as the tide receded. Fishermen in the video can be seen keeping the whales moist and helping them return to the ocean as the tide rises again. According to users online, this event happened just a day before the earthquake and near its epicenter, sparking speculation that the whales' behavior was a warning sign of the disaster. Tired of too many ads? go ad free now One social media user wrote, 'THE ANIMALS WARNED US – AND WE DIDN'T LISTEN. Just yesterday, five beluga whales washed ashore in Kamchatka, Russia, the exact epicenter of today's record-shattering magnitude 8.8 earthquake. Nature always knows first. This was the warning.' Are animals nature's early warning system? Throughout history, animals showing unusual behaviour before natural disasters have puzzled scientists and the public. For example, before the devastating 1975 earthquake in Haicheng, China, authorities noticed nervous animal behavior and evacuated residents in time. Similarly, during the 2004 Indian Ocean tsunami, many animals fled to higher ground ahead of the disaster, alerting nearby humans. It is believed that many animals can sense changes in the Earth's magnetic field or pick up on vibrations and subtle environmental cues humans cannot detect. Beluga whales, known for their social nature and unique features like their 'melon' forehead, might be among these sensitive creatures. However, experts caution that while these observations are intriguing, they require further scientific validation and proof. Beluga whales are sensitive creatures Belugas are distinct white whales known for their social pods and ability to navigate vast ocean spaces. Born grey or brown, they gradually turn white by age five. Their large forehead, called a melon, helps with echolocation, making them skilled at sensing underwater environments. Some scientists say that animals like belugas may detect subtle changes in Earth's magnetic field, helping them anticipate seismic activity. While the authenticity of the viral video remains unverified, some suggest it could be old footage.

Can Scientists Predict Earthquakes? Here's What We Know
A powerful magnitude 8.8 earthquake struck Russia's Far Eastern Kamchatka coast on Wednesday (July 30), triggering tsunami warnings across the Pacific. It was one of the strongest quakes ever recorded in history, and also sparked the age-old debate whether earthquakes can be predicted. The epicentre of the earthquake was near the city of Petropavlovsk-Kamchatsky, with scientists saying that bigger aftershocks cannot be ruled out. The quake was the biggest earthquake since the devastating event in 2011, which caused a tsunami that sent the Fukushima Daiichi nuclear power plant into meltdown. The US Geological Survey (USGS), 2011 earthquake was the largest earthquake ever recorded in Japan and the fourth largest recorded worldwide since 1900. Official data stated that the number of those confirmed dead or listed as missing from the 2011 disaster was about 18,500. Another data estimated it to be at least 20,000. As per reports, the majority of those killed were drowning victims of the tsunami waves. Can We Predict Earthquakes? No, USGS scientists cannot predict earthquakes. While they said that they can calculate the probability of a significant earthquake occurring in a specific area within a certain timeframe, predicting the exact time, location, and magnitude of an earthquake is currently not possible. Why Is Earthquake Prediction Challenging? According to USGS, an earthquake prediction must define three elements: the date and time, the location, and the magnitude. Earthquakes result from complex geological processes. Faults are hidden beneath the Earth's surface. Stress builds up over long periods, making it difficult to determine when an earthquake will occur. "Stating that an earthquake is going to occur today is not really 'predicting earthquakes'. To date, they cannot be predicted. But anyone, on any day, could make this statement and it would be true. This is because several million earthquakes occur annually; thereby, thousands occur each day, although most are too small to be located," USGS wrote on its website. What Can Be Done? USGS said that its scientists focus on assessing earthquake hazards and risks. They develop earthquake forecasts based on historical data and geological research. These forecasts help inform building codes, emergency preparedness, and public education. "The USGS focuses its efforts on the long-term mitigation of earthquake hazards and by helping to improve the safety of structures, rather than by trying to accomplish short-term predictions," it wrote.
