Watch the waves from the M6.4 #PuertoRicoEarthquake roll across the USArray Transportable Array seismic network (usarray.org )!
This animation, called a Ground Motion Visualization (GMV), shows the motion of the ground as detected on USArray seismometers - each dot is a seismic station and when the ground moves up it turns red and when it moves down it turns blue - the vertical motion.
Waves generated by an #earthquake travel around and through the earth, but they get smaller (attenuate) as they move away from the earthquake location, just like ripples in a pond.
As you think about Puerto Rico, remember this and get angry:
the Trump Administration has illegally withheld $18 bil in funding approved by Congress 2 yrs ago to rebuild critical infrastructure and schools.
Some of these buildings didn’t stand a chance.

Further, the power is out on the entire island. Many people suffered - and many died - post-Maria because they relied on electricity for life saving medical equipment. The federal government needs to announce immediately how they plan to help. #PuertoRicoEarthquake
