following the Great East Japan Earthquake in 2011. Since 2013, the two universities have been conducting cohort studies,
#Researchers test smartphones for earthquake warning The study, led by scientists at the U s. Geological Survey
and similar devices could be used to build earthquake warning systems. Despite being less accurate than scientific-grade equipment,
the GPS (Global positioning system) receivers in a smartphone can detect the permanent ground movement (displacement) caused by fault motion in a large earthquake.
earthquakes could be detected and analyzed, and customized earthquake warnings could be transmitted back to users.""Crowd-sourced alerting means that the community will benefit by data generated from the community,
"said Sarah Minson, USGS geophysicist and lead author of the study. Minson was a postdoctoral researcher at Caltech
Earthquake early warning systems detect the start of an earthquake and rapidly transmit warnings to people and automated systems before they experience shaking at their location.
While much of the world's population is susceptible to damaging earthquakes, EEW systems are currently operating in only a few regions around the globe,
"Most of the world does not receive earthquake warnings mainly due to the cost of building the necessary scientific monitoring networks,
Researchers tested the feasibility of crowd-sourced EEW with a simulation of a hypothetical magnitude 7 earthquake,
and with real data from the 2011 magnitude 9 Tohoku-oki, Japan earthquake. The results show that crowd-sourced EEW could be achieved with only a tiny percentage of people in a given area contributing information from their smartphones.
the earthquake could be detected and analyzed fast enough to issue a warning to areas farther away before the onset of strong shaking."
"The speed of an electronic warning travels faster than the earthquake shaking does explained Craig Glennie, a report author and professor at the University of Houston.
and similar devices could be used to issue earthquake warnings for earthquakes of approximately magnitude 7 or larger,
but not for smaller, yet potentially damaging earthquakes. Comprehensive EEW requires a dense network of scientific instruments.
will be able to help minimize the impact of earthquakes over a wide range of magnitudes.
"The U s. earthquake early warning system is being built on our high-quality scientific earthquake networks, but crowd-sourced approaches can augment our system
Douglas Given, USGS coordinator of the Shakealert Earthquake Early warning system. The U s. Agency for International Development has agreed already to fund a pilot project, in collaboration with the Chilean Centro Sismologico Nacional,
to test a pilot hybrid earthquake warning system comprising stand-alone smartphone sensors and scientific-grade sensors along the Chilean coast."
"Thirty years ago it took months to assemble a crude picture of the deformations from an earthquake.
but for larger earthquakes that cause large shifts in the ground surface, they contain enough information to detect that an earthquake has occurred,
#The Quake that Shook Mt everest The earthquake, which wreaked havoc in the Kathmandu Valley of Nepal on Saturday about noon local time,
The large quake triggered a major avalanche on the south slopes of Mt everest which devastated the base camp,
More than a dozen people are feared to have died in the avalanche. Mt everest lies 140 miles east of the epicenter.
The earthquake caused huge cracks to open in the streets of Kathmandu. The Nepalese capital lies in a sediment filled basin,
Calculations by all major earthquake monitoring agencies in the US and Europe put the depth between 7 and 10 miles.
During the shaking of an earthquake such sedimentary basins tend to amplify the ground motion
The worst historic effect of this kind led to the huge destruction in Mexico city during an earthquake in 1985.
The cause for Saturdays earthquake is the northward movement of the Indian Plate. It crawls with a speed of about 2 inches per year, roughly the same rate with which the Pacific Plate slides past North american in our area.
This plate collision also causes some of the most devastating earthquakes in the world. In the last 125 years, this eastern section of the Himalayan Front alone has seen at least three quakes of magnitude 8 or greater.
The report they published one year later on the likely earthquake scenario makes very eerie reading,
#Nepal earthquake on the radar Radar imagery from the Sentinel-1a satellite shows that the maximum land deformation is only 17 km from Nepal capital, Kathmandu,

#Cheap Earthquake Warning Systems While predicting earthquakes remains a dream, scientists have developed early warning-systems systems that give people precious seconds to run out of buildings
That kind of warning might have saved hundreds of lives when a 7. 8-magnitude earthquake devastated Nepal on 25 april.
Earthquake-warning systems come at a high price, though, too high for countries like Nepal and others in quake-prone zones in South Asia,
along with GPS sensors to detect permanent ground movement due to the motion of the geological fault that triggers the earthquake.
If the latter, the system will calculate a hypothetical epicenter for the earthquake, the original time of the event,
For earthquakes with magnitudes greater than 4. 0, it will issue an alert. Benjamin Brooks, a geophysicist with the USGS, has a different crowdsourcing approach in mind.
with high earthquake hazards and minimal resources, is where a crowdsourcing approach would be most effective,
In research presented in the journal Science Advances two weeks before the Nepal quake hit, Brooks and his colleagues tested the ability of consumer-grade GPS devices to detect earthquakes.
Next, the researchers performed simulations using data from a hypothetical magnitude-7 earthquake in northern California and from the real 2011 magnitude-9 earthquake that hit Tohoku-oki
They simulated smartphone responses based on census data around the earthquake epicenters and recorded a phone as triggered
the system declared an earthquake. It took fewer than 5, 000 smartphones to detect the simulated California earthquake within 5 seconds,
giving enough time to warn San francisco and San jose. For the Japan quake, which had an offshore epicenter,
on the Wednesday before the Nepal earthquake I had a discussion with a Nepalese colleague about proposing precisely such an approach,
whose research suggests that earthquakes could cause carbon dioxide gas to leak out of underground storage sites,

#At $50, Earthquake Early Warning device Could Ease Lives of Billions Startup Grillo wants everyone, especillay developing nations,
to have earthquake early warning-systems systems for increased public safetyan earthquake measuring device is priced at about $20,
The dream is to allow even developing nations affordable early warning devices that can warn against the destructive power of earthquakes.
there is no effective way to predict an earthquake hours earlier. Japan, the only country in the world with a nationwide advanced early warning system
can only send alerts mere seconds before an earthquake can happen. But this crucial warning has proven itself a lifesaver.
when the most powerful earthquake Japan has seen ever rocked the nation, early warning systems halted trains and is believed to have minimized significantly damage to both infrastructure and the number of casualties.
Expert seismologists will place the sensors for better chances of coming across the early stages of an earthquake.

Thomas Walter. On one hand we are analysing data from the newest remote sensing satellites to develop models of the magma ascent path.
The satellite data which is acquired by the European space agency's Sentinel-1 satellite enables the measurement of ground movements associated with the volcano eruption.
and following the path of the magma from depth to its point of eruption. As a result the location of the ascent paths at depth explains well why the eruption site is off-centered with respect to the volcano summit.
which allows for regular updates on the ground movement and the magma ascent path beneath.
The magma's eruption rate has decreased but concerns have arisen about a recent increase of the explosive character of the eruption and related ash dispersion.
