Like a steaming kettle with the top on, pressure is building beneath the surface of California that could unleash a monster earthquake at any time. That’s according to a new study from the Scripps Institute of Oceanography.
Geologists say Southern California is long overdue for a huge earthquake that could unleash widespread damage.
It all comes down to the Salton Sea, which lies to the east of San Diego. The Salton Sea lies directly on the San Andreas Fault and covers more than 350 square miles.
A big earthquake has hit the lake bed about every 180 years. But when officials started damming the Colorado River to reduce floods downstream (including in the Salton Sea), the moderate earthquakes stopped for the Salton.
Sounds like a good thing, right? Not necessarily. Seismologists think the Read more…
Quake felt across central New Zealand
LATEST: A deep earthquake measuring 6.5 has been widely felt across the lower North Island, but there were no initial reports of damage.
GNS Science said the earthquake was a magnitude 6.5, centred 150km deep, 30km west of Taupo. It struck at 3.36pm.
Initial reports on GNS’ website show the quake was felt in Wellington, Nelson, New Plymouth and up to the Coromandel.
GNS volcanologist Brad Scott said although the earthquake was centred near Taupo it was more likely felt on Read more…
Indonesia Hit By Strong Earthquake, Latest On Ring Of Fire
Indonesia was hit by a large earthquake and a series of strong tremors Sunday afternoon. A 6.5 magnitude quake, the latest in string of strong quakes to hit the Pacific Ring if Fire region during the last week, struck the country’s easternmost Province of Papua 1.16 p.m. GMT.
The quake was centred 53 kilometres (33 miles) northeast of Waren, a town on the northern coast of Papua island, according to Indonesia’s Meteorology and Geophysics Agency. It was also felt in nearby Biak island, and Enarotali town on the main island The U.S. Geological Survey put the initial quake’s magnitude at 6.4.
The region was hit by at least moderate tremors in the following hours. The tremors measured 5.4 (x2), 5, 4.5 and 4.3 on the Richter Scale. There were no immediate reports of damage and no tsunami warning was issued.
Papua comprises most of the Read more…
Tectonic plates rattle- more turbulence at the South Pole
June 21, 2011 – ANTARCTICA – A 5.5 magnitude earthquake struck the South Sandwich Islands region, situated around 750km south east of South Georgia, in the South Atlantic early Sunday. It was the latest in a series of quakes to hit the Antarctic Region during the past 24 hours. The moderate quake struck at 9.37am GMT at a depth of 137km and was centered 69 km (42 miles) NNW of Visokoi Island and 330 km (205 miles) NNW of Bristol Island. The last significant earthquake to be recorded in the South Sandwich Islands region occurred on Read more…
Number Of Recorded Earthquakes Rises Sharply
2011 is on target to record the largest number of earthquakes in a single year for at least 12 years.
Research by Irish Weather Online, using data from the US Geological Survey (USGS), has found that earthquake activity (5.0-9.9 magnitude) from 01 January to 19 June 2011 is already exceeding the total annual seismic activity for the years 2001, 2002 and 2003. 2011’s total number of recorded earthquakes is also expected to exceed the most seismically active year of the past 12 years, 2007.
A total of 1,445 earthquakes, ranging in magnitude from 5.0 to 9.9, have been recorded in the year up to 19 June. The total number of earthquakes recorded globally for the entire of 2007 was 2,270.
The massive earthquakes in Japan (2011), Chile (2010), Sichuan (2008), Sumatra (2005 and 2008) and Indonesia (2004) have served to remind us of the devastating impact of earthquakes on life and property. While the number of earthquakes ranging Read more…
Chile Earthquake Today – Terremoto Felt in Santiago
CORAL GABLES (LALATE) – – Chile was struck by a 6.4 earthquake today. Chile’s earthquake or terremoto was felt in Santiago and struck during the morning rush hour. Today’s temblor is the latest powerful earthquake to strike the country this year. No reports of damage or injury today have been given.
Today’s earthquake activity in Chile produced the highest quake in the region in recent weeks. In April, Chile experienced two major earthquakes with hours of each other. On April 2, a moderate 5.1 quake struck forty-one miles south of San Antonio, Valparaiso. That temblor was followed hours later by an earthquake registering a 5.9 magnitude, centered eighty-three miles east of Iquique in the Tarapaca region stuck.
Like the April earthquakes, today’s temblor struck during the early morning Read more…
Possible Earthquake might be eminent SE-Illinois
Experts: Mega-Quakes Can Create Pole Shifts
Mega-thrust earthquakes like the ones that recently struck Chile and the Fukushima region of Northern Japan, can cause the magnetic field to flip. If a quake is strong enough there is evidence it may even set off a geological pole shift tossing the Earth off its current axis and killing billions of people within a matter of minutes.
This the grim picture painted by decades of research and evidence strewn from the peaks of the Andes to the volcanic shards lying off the Pacific islands of Hawaii.
Cities could be swept away in the blink of an eye
Enormous earthquakes cause enormous damage. The threat is real and growing, as world renown physicist and popular science author, Dr.Michio Kaku , recently explained on ABC’s “Good Morning America.”
According to Dr. Kaku, some of the world’s most important and populated cities could be swept away in the blink of an eye. “In our life time, we could very well see one of these cities destroyed,” Kaku claimed. “Los Angeles, San Francisco, Mexico City, Tehran, and Tokyo.”
It is actually Mankind and not nature that has placed up to one billion people at risk. “We are creating mega cities where there used to be Read more…
Time to shift view of seismic risk – experts
 |
Knowledge of seismic risk is badly skewed in favour of earthquakes that occur on plate boundaries, such as the March 11 temblor that hit northeast Japan, rather than those that strike deep inland, a pair of scientists said on Sunday.
In commentary appearing in the journal Nature Geoscience, Philip England of Oxford University and James Jackson of Cambridge University say that in seismic terms, the 9.0-magnitude Sendai quake was “a remarkable story of resilience.”
Good civic training and building construction meant that the death rate was “impressively low,” they said. Around 25,000 people died, or 0.4 percent of those exposed to the event, and most of these died from the tsunami that followed.
The March 11 event occurred on a plate boundary, where the jigsaw of plates that float on Earth’s crust jostle and grind and slide under each other.
England and Jackson say plate boundaries are relatively well-studied, but a far greater threat lurks in continental inland areas.
“Death rates in earthquakes within continental interiors have often exceeded five percent and can be as high as 30 percent,” they warn.
According to their count, over the past 120 years, there have been around Read more…
Atmosphere Above Japan Heated Rapidly Before M9 Earthquake
Infrared emissions above the epicenter increased dramatically in the days before the devastating earthquake in Japan, say scientists.
Technology Review
Published by MIT
Geologists have long puzzled over anecdotal reports of strange atmospheric phenomena in the days before big earthquakes. But good data to back up these stories has been hard to come by.
In recent years, however, various teams have set up atmospheric monitoring stations in earthquake zones and a number of satellites are capable of sending back data about the state of the upper atmosphere and the ionosphere during an earthquake.
Last year, we looked at some fascinating data from the DEMETER spacecraft showing a significant increase in ultra-low frequency radio signals Read more…
