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.

but not for smaller, yet potentially damaging earthquakes. Comprehensive EEW requires a dense network of scientific instruments.

#The Brazilian deforestation puzzle Brazil rate of deforestation went down dramatically over the last ten years.
the decade-long decrease in deforestation. What was behind that? One possible reason, advanced by ecologist Philip Fearnside in an interview on Yale 360,
which was in the opposite direction of increasing deforestation. Both economic circumstances and the drivers of deforestation vary from place to place,
but it not obvious why the Brazil living in the same world economy as Peru,
Bolivia, and other countries with tropical forest should have responded to global economic changes with a big dip in deforestation
while the deforestation in the other countries grew sharply. Also, deforestation decreases in different Brazilian states weren lockstep,
which also suggests the possibility that uniform national forces applying to the whole country may not be the complete explanation.
when deforestation was falling. The other plausible cause involves Brazil forest policy. Brazil adopted a number of anti-deforestation measures,
including increased enforcement. In a particularly interesting move the government used its controls of state banks to deter agriculture
These policies are being studied carefully in other countries with deforestation problems. It frustrating that we don have better empirical analysis of the role of policy
Satellite evidence suggests that deforestation has doubled in the past year. The government has confirmed this shift. The reasons for this change are also unclear.
which may have made profits from deforestation more appealing compared to the alternatives. There an oddity about where deforestation is increasing.
In 2013, deforestation in Pará was about as great as in Rondônia and Mato grosso combined.
see this chart. But in 2014, each of those state had more deforestation than Pará (see here.
There seem to be two possible explanations. One is that the drivers of deforestation in those states are much different,
so countrywide economic or legal changes have very different effects in each state. Mato grosso, for example, is a far bigger soybean producer than the other two states.
along with national policy, in the earlier decrease in deforestation, so maybe changes at those levels are part of the current increase.
The most obvious explanation for the overall trends is the change in national policy first to sharply restrict deforestation,
we can only hope that Brazil gets back on track in its efforts to control deforestation

The large quake triggered a major avalanche on the south slopes of Mt everest which devastated the base camp,

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.
