An underwater volcano 300 miles off the coast of Oregon has awakened from its slumber and apears to spew out lava. There is no immediate danger, but geologists are excited to be able to study it in real time.
There's so much you can do with a smartphone today - much more than just browsing the web or social media. When you can combine them in a network, however, the possibilities might be endless. For instance, researchers at Caltech and the United States Geological Survey (USGS) are working on an earthquake early warning system based on the collective data fed in by thousands of smartphones. Only a couple of countries in the world give vulnerable cities an early warning - often just enough time to hit cover and save your life - but smartphones are virtually ubiquitous all over the world, even in poor countries which lack basic infrastructure like roads or flushing toilets.
A magnitude 6.8 earthquake (initially 6.9) has struck Northern Japan earlier today, with a small tsunami striking the coast without any significant damage. The tsunami was on the order of tens of centimeters. There was some worry, despite Japan being one of the most well prepared countries in the world to deal with earthquakes. “Overall, the […]
Hydraulic fracking is responsible for a swarm of earthquakes, one of which was felt by Ohio residents in March 2014, a study has found. While the earthquake hag a magnitude of only 3.0 degrees, it is believed that it may have activated a geological fault and may ultimately lead to more significant temblors.
A team of geologists from Iceland, Sweden and Saudi Arabia has found changes in groundwater chemicals prior to earthquakes. They emphasize that they haven’t found a precursor to earthquakes, but there seems to be a connection between these chemical changes and incoming earthquakes. There is no reliable earthquake warning system, and there almost certainly won’t […]
Chile is one of the most seismically active countries in the world. In 2010, it was struck by a powerful 8.8 earthquake which produced temblors throughout the entire country, as well as in Peru and Argentina. But a new study concluded that its effects were felt even further, in Antarctica, where several seismic stations recorded “icequakes,” probably […]
Geologists working in New Zealand have shown, through isotopic analysis, that rainwater can infiltrate down to 6-8 km, in the lower ductile crust.
For the first time, geophysicist in New Zealand will place seismic sensors deep into a geological fault to record the build-up and occurrence of massive earthquakes, potentially giving crucial information about one of the biggest faults in the world. It’s hard to say anything after such an insightful and well explained video. The Alpine Fault […]
They don't scientific instruments this classy anymore.
A 7.9 magnitude earthquake has struck deep beneath the ocean floor near Alaska’s Aleutian islands, triggering a small tsunami. Initially, a tsunami warning was issued for the area, but it was then downgraded to an advisory. Still, 200 residents of the town of Adak were evacuated to higher ground. The good news is that no injuries was […]
French researchers say they are close to developing seismic ‘invisibility cloaks’ which would cancel out potentially hazardous earthquake shockwaves, protecting key buildings or even entire cities. Nuclear power plants especially, and potentially entire cities could be cloaked using this technology – if the researchers’ theories are true (which seems highly likely). They believe that by drilling boreholes […]
An 8.2-magnitude earthquake hit near the coast of Chile last night, triggering multiple strong aftershocks and a 6-foot (3 meter) tsunami. There have been at least five confirmed casualties, with the victims being crushed or suffering from heart attacks. “The fact is, we will know the extent of the damage as time goes by and […]
In a new study conducted by researchers at the U.S. Geological Survey, researchers showed that the human-induced magnitude 5.0 earthquake near Prague, Oklahoma in November 2011 further caused a larger M5.7 earthquake less than a day later. We’re talking about two human induced earthquakes with magnitudes of 5 and above, in less than a day, […]
A magnitude 6.9 earthquake off the coast of Northern California struck Sunday night, on the 9th of March. It was the largest on the West Coast since the 7.2 Baja California quake in 2010 and it was followed by a series of at least 13 aftershocks, the largest of which had magnitude of 4.6, according […]
Scientists have developed a new catalogue of earthquake lights, glows sometimes reported during the seismic shaking, and sometimes even before it. The phenomenon has been reported by eyewitnesses for centuries, but only recently did scientists start taking them seriously. The science of glowing earthquakes Even though they have been described both before and during the […]
A tiny chip already used in smartphones for the orientation of your screen could serve to create a real-time urban seismic network, easily increasing the amount of strong motion data collected during a large earthquake, helping responders know where the most damage has been done and where the strongest intervention is needed. Micro-Electro-Mechanical System (MEMS) […]
The Earthquake A major earthquake hit a remote part of Pakistan (near the border with Iran), claiming 45 lives and prompting a new island to rise from the sea just off the country’s southern coast. According to the USGS, the earthquake has a magnitude of 7.7 and tremors were felt all the way to New […]
A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013 still poses a lot of questions to geophysicists. At a depth of about 609 kilometers (378 miles), the kind of rupture which generates an earthquake of this magnitude should just not happen. The vast majority of significant earthquakes takes […]
Lots of volcanoes erupted in 2009 – but one of them really screamed out. Its unique howls provide a glimpse into the very heart of the volcano, and also in some unexplained processes that accompany an eruption. It’s not unusual for swarms of small earthquakes to precede a volcanic eruption – it’s quite common. As […]
As bad as earthquakes can be, and we’ve recently had our fair share of earthquakes around the world, the tsunamis they generate can be even worse. When an earthquake has a significant effect in a body of water, it displaces large quantities of water – and it is that displacement which causes the huge waves […]
Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth’s mantle that may be acting as a lubricant for the sliding motions of the planet’s tectonic plates. This discovery has very far reaching implications, which can solve some of the long standing geological puzzles, as […]
A massive earthquake struck Wednesday east of Kira Kira in the Solomon Islands, with several already confirmed victims and injuries. “At 12 minutes past midday, a 7.9 earthquake in the Santa Cruz Islands (near the Solomon Islands) occurred. A shallow event.” He said. “The nearest part from our location estimate is an island called Ndeni, […]
It should be no surprise for anybody that a major earthquake is way overdue in LA; a study has shown that the area has a 99% chance of a big earthquake in the next 30 years (well, 25 years, since the study was conducted in 2008). Even with what should have been a huge wake […]
The United States Geological Survey (USGS) reported an undersea earthquake with a magnitude of 6.4 some 142 kilometers off the coast of Baja, California. The earthquake had its origin at approximately 10 km below surface level and so far, no tsunami warning has been issues. Tectonic setting Sitting ontop of three of the large […]
A strong earthquake with an epicenter off the northeastern coast of Japan shook buildings all the way to Tokyo, leading to a tsunami warning for coastal areas of the northeast. The first estimate of the magnitude was 7.4, but was then lowered to 7.3. The United States Geological Survey (USGS) explained there is no risk […]
In 2011, a 5.1 magnitude earthquake struck the Spanish city of Lorca, resulting in the loss of 9 lives and the injury of over 100 people. Now, researchers studying the case believe groundwater extraction played a crucial role in triggering this earthquake. A fault is a planar fracture or discontinuity in a volume of rock, across which […]
Scientists from China, US and Mexico have used light detection and ranging laser altimetry (LiDAR) to study how an earthquake can change the surrounding landscape. Using this technique, the researchers were able to establish with high accuracy where the Earth’s crust ruptured. If the same technique were to be established around all major high-risk areas for earthquake, […]
This summer Japan was hit by a tremendous 9.0 Richter scale earthquake, which generated one of the most powerful tsunamis in recorded history. The event killed thousands, left countless others homeless, caused major damage to the Fukushima nuclear power plant , which lead to radiation leakage and more than $130 bln in damage. Now, new details […]
Right now, you’re probably asking ‘how does an earthquake look like in 3D ? What does that even mean?’; well, brilliant artist Luke Jerram created the small piece you see below to contemplate the 2011 Tōhoku earthquake. He did this by taking a seismograph recording of the event and rotating it in 3D. The piece […]
Another powerful seismic event has taken place, this time in Turkey; the 7.2 earthquake in case struck eastern Turkey on Sunday, killing at least 60 people and turning most buildings into big chunks of concrete and metal. However, Turkish scientists grimly predict that the victim count could easily go above 1000, as housing conditions are […]
In 2008 a deadly earthquake hit the Sichuan province of China killing tens of thousands and living millions homeless – it was the most devastating natural disaster in China’s recent history. From the among the rubles of the quake, however, emerged a survivor-pig which made him an instant national hero at the time. Now, Chinese […]
A small, yet frightening earthquake, registered at 5.9 magnitude, sent shivers down people’s spines all the way from Ottawa, Canada to North Carolina as it hit the North American east coast. The earthquake first caused ground shacking at 1:51 p.m. ET, when it measured 5.9 in magnitude and lasted only 45 seconds, according to the […]
Increased heat emissions by a volcano located in the Aleutian were detected via satellite by the Alaska Volcano Observatory, which has issued an eruption advisory alert. Recent activity has increased the volcano to a Yellow Alert. Mt. Cleveland, 5,676 ft. AGL, also referred to as Cleveland volcano is emitting seismic activity that seems to correlate with the […]
Topping this week’s absurd news by far, this is one of the most preposterous things I’ve read in all my life. Seven seismologists are charged with manslaughter after they failed to predict the 2009 L’Aquila that made 300 victims. Earthquake prediction and other fairytales At the moment, and in the forseeable future, it is impossible […]
Contrary to what you might expect, a recent published study unveiled by scientists shows a map of our planet’s gravity, which resembles not a sphere, but more a … potato. This is because the Earth’s gravity isn’t uniform, being affected everyday by such factors like winds, currents and tides, so because gravity is higher in […]
Ever since the 9.0 earthquake in Japan, there has been a growing mainstream interest for earthquakes, which will probably fade away as time passes, only to be revived when the next big temblor strikes. However, the good news is that, even for a brief period of time, seismologic studies are given the attention they […]
The massive 9.0 earthquake was the last in a series that devastated countries across the boundary of the Pacific plate. Even Japan, perhaps the country who was the most prepared in the world for this kind of seismic activity, was hopeless in front of the temblor and the tsunamis it created. But after the earthquakes […]
You don’t get any country better prepared for an earthquake than Japan. They know they are at risk, they are prudent, they have the money, the technology, and the work force; and yet, when hit by an earthquake of this magnitude, no matter how well prepared you are, you are in for some massive trouble. […]
The sad loss of over 10.000 people caused by the M8.9 earthquake and the tsunamis it generated is not the only problem Japanese people will have to deal with; this major disaster is also the most costly in world history, a “title” previously held by Katrina in the US, with an estimate of £77 billion […]
A National Geographic documentary is on the lookout for the mysterious lost city of Atlantic.
In its wake, the Japan 8.9 Richter scale devastating earthquake and the huge tsunami that was produced by it left inimaginable damage. Homes simply stripped apart, farm areas swept away by the water, airports raised, nuclear power plants dangerously shaken and a concerning death toll made the world tremble and reinforced the idea that nature […]
As a consequence of last Friday’s devastating earthquake near the coast of Japan, the nation’s most powerful recorded earthquake to date actually since it began archiving results in the late 1800, scientists have assessed that the Earth axis has tilted by a few inches and that the chronological day has been shortened by a millionth […]
If you’re looking for an easy to understand scientific explanation about the formation of the devastating quake and tsunami that devastated Japan this Friday, you’d better read Dr. John Ebel‘s theory from below, Professor of geophysics and director of Weston Observatory of Boston College. “We had an earthquake caused by the Pacific Ocean plate sliding […]
The recent tsunami wave that hit the Japanese coast this Friday simply devastated the countries costal areas. Besides the actual casualties (now reported to around 1,700), there are a few thousand people still isolated (footage of Japanese citizens stranded on rooftops have been circulating everywhere recently) and thousands more left homeless. The Japanese Government and […]
In the wake of Japan’s most devastating recorded earthquake to date, the nation of the rising sun is still left in shock. Hundreds were killed, many more left homeless, countless financial damage and entire cities left with electricity – it might even get a heck of a lot worse. Another big issue is the telecom […]
The damage caused by the 8.9 earthquake in Japan is far from being over – asa matter of fact, unfortunately, it may very well just be starting. The earthquake and the tsunamis it created cut down power supply throughout a major part of Japan, and so the cooling system of several power plants was unable to […]
The earthquake that occured yesterday near the coast of Japan, the 4th most powerful earthquake ever to be recorded, is causing even more problems, after the direct damage, the aftershocks, the tsunamis, and the fire tsunamis; this time, things can get way, way bigger and worse, and the disaster toll keeps rising. An explosion at […]
The earthquake that struck Japan is much worse than original estimates ! The original 7.9 magnitude actually just got upgraded to 8.9, which makes it 10 times more powerful, and the 4th most powerful earthquake in the past 100 years. Sadly, reports of injured and killed people keep coming in, and will likely not stop […]
It’s been a busy tectonic month, and things aren’t about to chill down. A massive 7.9 magnitude Earthquake has just hit the Northern coast of Japan, triggering a more than four meter tall tsunami that wiped down cars and other property along the coastline, but it’s still unclear how many people were injured or killed. […]
It’s time we face it, a big one is coming – and soon ! All the predictions point towards a major earthquake near the San Andreas fault in a short time, and Los Angeles will suffer the most of it. A recent study published in the Bulletin of the Seismological Society of America confirmed that […]
