A decade after beginning work on an earthquake early warning system, scientists and engineers are fine-tuning a US West Coast prototype that could be in limited public use in 2018.

New early gravity signals to quantify the magnitude of strong earthquakes
2017-12-19 10:23:54November 30, 2017
After an earthquake, there is a disturbance in the field of gravity almost instantaneously. This could be recorded before the seismic waves. Researchers have managed to observe these weak signals and to understand where they come from. Because they are sensitive to the magnitude of earthquakes, these signals may play an important role in the early identification of the occurrence of a major earthquake.

Earthquake Near Iran-Iraq Border Kills More than 430, Injures Over 7,600
2017-11-15 09:43:40
At least 437 people were killed and more than 7,600 others injured after a 7.3-magnitude earthquake struck near Iran's border with Iraq, authorities said Monday.
In Iran, rescuers who worked through dozens of aftershocks and were hindered by landslides ended their efforts late Monday night/early Tuesday morning, the country's top emergency management official, Pir-Hossein Kolivand said, according to Reuters.
Many houses in rural areas of Iran are made of mud bricks that can crumble easily in a quake.
The official Islamic Republic News Agency in Iran said the quake killed 430 people and injured at least 7,100. And Iraq's Interior Ministry confirmed that seven people in the neighboring country were killed by the quake, with 535 people wounded.
Other reports put the death toll in Iran at more than 450.
Western US Quake? Fifty simulations of the 'Really Big One' show how a 9.0 Cascadia earthquake could play out

The largest number yet of detailed simulations for how a Cascadia Subduction Zone earthquake might play out provides a clearer picture of what the region can expect when the fault unleashes a 9.0 earthquake.
