The initial tsunami wave created by the eruption of the underwater Hunga Tonga Ha'apai volcano in Tonga in January 2022 reached 90 meters in height, around nine times taller than that from the highly destructive 2011 Japan tsunami, new research has found. An international research team says the eruption should serve as a wake-up call for international groups looking to protect people from similar events in future, claiming that detection and monitoring systems for volcano-based tsunamis are '30 years behind' comparable tools used to detect earthquake-based events. Dr. Mohammad Heidarzadeh, Secretary-General of the International Tsunami Commission and a senior lecturer...

Three weeks ago, we showed readers what happens when the infamous “Bullwhip effect” reversal takes place by presenting the unprecedented surge in the “Inventory to Sales” ratio for a broad range of US retailers covering the furniture, home furnishings and appliances, building materials and garden equipment, and a category known as “other general merchandise,” which includes Walmart and Target. Since then, this ratio has only gotten even more extended, and as shown below it is now at the highest level since the bursting of the dot com bubble! What does this mean for retailers and the price of goods? Three...

China faces an omicron “tsunami” that could overwhelm hospitals and kill more than 1 million people if it abandons its “zero-Covid” strategy, according to a new study published in Nature Medicine on Tuesday, as officials double down on the controversial policy despite worsening social and economic damages of such strict lockdowns.

Scientists have found evidence that an earthquake 3,800 years ago in Northern Chile is the largest in human history, according to a new study. The quake had a magnitude of around 9.5, prompting tsunamis that struck countries as far away as New Zealand and boulders the size of cars to be carried inland by the waves, according to researchers at the University of Southampton. Since earthquakes occur when two tectonic plates rub together and rupture, a longer rupture indicates a bigger earthquake, they said. "It had been thought there could not be an event of that size in the north...

In a study published in Geophysical Research Letters on February 8, scientists said that a total of five earthquakes, including one massive, "hidden" tremor, created the tsunami after striking close to the South Sandwich Islands on August 12, 2021, in the remote Southern Ocean off the coast of the continent of South America. The study showed that tsunami-causing earthquakes such as the August 12 incident had complex patterns that could confound how scientists measure major tectonic activity Researchers described an initial rupture that happened deep below the oceanic crust in between the South American and South Sandwich tectonic plates at...

Beaches along the Oregon coastline warned tourists and residents of the danger, including “strong currents and dangerous waves.” With the threat of water potentially rising 1-3 feet higher than normal, the National Weather Service advised people to stay out of the water and away from the shore. However, people who live and work in the coastal town tell KOIN 6 News after they heard the siren and got the emergency alert on their phones — they saw people doing the exact opposite. “The next thing you know, we hear people outside and they’re running to the beach – which I...

The eruption of Hunga-Tonga-Hunga-Ha'apai volcano, which sits on the seismically active Pacific Ring of Fire, sent tsunami waves across the Pacific Ocean and was heard some 2,300 kms (1,430 miles) away in New Zealand. [O]n-site instruments were likely destroyed in the eruption and the volcanology community was pooling together the best available data and expertise to review the explosion and predict anticipated future activity. Saturday's eruption was so powerful that space satellites captured not only huge clouds of ash but also an atmospheric shockwave that radiated out from the volcano at close to the speed of sound. Photographs and videos...

What'd I miss? There was supposed to be a 2ft tsunami warning along the Pacific Coast. Should have arrived 7:30 to 8:30 am PDT. Did anyone see it?Tsunami Warning/ Entire US West Coast - YouTube

BREAKING: Tsunami warning issued for American Samoa after Tonga's Hunga volcano erupts

This is better than anything our media has produced. I don't know about death totals or anything, but it's impressive the power of a tsunami. I had to edit the title, just to show what it was about because there is no English

Active swarm of earthquakes happening this am.

Eighteen earthquakes have struck Tuesday off the Oregon coast, with the largest two reaching magnitude-5.8. The earthquakes hit far off the coast, roughly west of Newport. No tsunamis are expected. Small earthquakes strike often near Oregon’s coast, a regular reminder of the cataclysmic earthquake geologists say will happen when the pressure building between the Juan de Fuca and North American plates breaks

The first jolt, which struck off the coasts of Japan’s remote Bonin Islands, was recorded at magnitude 7.9 and up to 680 kilometers (423 miles) underground, making it one of the deepest quakes of its size. Then another oddity emerged in the cascade of aftershocks that followed: a tiny temblor that, if confirmed, would be the deepest earthquake ever detected. The ultradeep quake, described recently in the journal Geology, is estimated to have struck some 751 kilometers (467 miles) beneath the surface in the layer of our planet known as the lower mantle, where scientists have long thought earthquakes unlikely,...

Seismic activity is slowly moving towards the southern part of La Palma. This is where a giant landslide could trigger a devastating tsunami. Within the last 2 days, more than 115 earthquakes have been located in the southern area of ​​the island of La Palma. Twelve of them were felt by the population and even four reaching an intensity III-IV in the epicentral zones. The largest earthquake, a M3.7, occurred at 19:14 UTC yesterday evening. Something big is brewing! This guy even suggests a new volcano could soon start erupting on the southern part of the island… Terrifying, no? As...

The island of La Palma in the Canaries was hit by an "earthquake swarm," with officials warning magma is building up under the Cumbre Vieja volcanic chain. Thousands of small earthquakes have hit the Canary island of La Palma in recent days while growing stronger and moving closer to the surface, according to the regional government. The Spanish island is the home of the Teneguia volcano in the Cumbre Vieja national park. A team of volcanologists warned that an eruption could be possible in the coming days, according to a report in the El Pais daily on Thursday. The team...

The strong earthquake swarm is continuing beneath Cumbre Vieja, and now PEVOLCA has raised the alert level to Yellow, citing the repeated occurance of earthquake swarms since 2017, with this one being the strongest and also the shallowest, suggesting magma is slowly rising into the edifice. Measurements of Helium-3 gas flux are also indicating this.

RUSSIA'S "city killer" submarine has set sail for the first time packed with nuclear drones capable of triggering monster tsunamis. The 604ft Belgorod - which is twice the size of the Royal Navy's Astute-class attack subs - reportedly took to the sea for the first time on Friday. The 14,700-tonne war machine bristles with nuclear-tipped underwater drone torpedoes - each guided by artificial intelligence. The secretive launch came after Vladimir Putin's navy vowed to sink British warships the next time they sail too close to Crimea. The war talk followed a face-off in the Black Sea where HMS Defender was...

The biggest earthquake, with a magnitude of 4.2, briefly startled lawmakers in session in the Nevada capital. There were no immediate reports of damage, but seismologists are concerned about a recent series of quakes near the lake and the potential for a tsunami. The biggest earthquake, with a magnitude of 4.2, briefly startled lawmakers in session in the Nevada capital. There were no immediate reports of damage, but seismologists are concerned about a recent series of quakes near the lake and the potential for a tsunami. It came as Lake Tahoe’s resorts and tourist destinations prepared for a Memorial Day...

A meteorite impact off Long Island 2,300 years ago may have set off a huge tsunami that flooded the New York City region, a new study says (New York City and Long Island map). It's not known whether any ancient settlements were in the path of the proposed killer waves, but "any significant tsunami today would be devastating and likely to flood places like lower Manhattan," Vanderbilt University geologist Steven Goodbred said. Tsunamis are typically triggered by seismic events. An undersea earthquake, for example, caused the catastrophic 2004 Indian Ocean tsunami. But meteorite strikes have also been known to spark...

Yesterday, I wrote about a major M7.2 earthquake off Colombia, first reported by all networks around the world before being deleted… I started searching and found a new scientific study published on April 19, 2021 that actually reports about a shallow and fully locked part on the Caribbean subduction zone in Colombia capable of creating destructive earthquake and tsunami in the northwest region, off Cartagena. Yesterday’s M7.2 ‘ghost’ earthquake happened exactly in the region where scientists predicted in the science paper. This may be one of the reason why the powerful earthquake was deliberately hidden from the public. What do...
