Vídeo divertido de terremoto, testando o Em4.

Don’t miss this video of a weather broadcast from Evansville, Indiana at around 4:30am last Friday, as an earthquake occurred.

Weather cameras mounted on towers and tall buildings turn out to be good seismometers.

Evansville’s about 40 miles from the epicenter. See USGS info aqui.

I tested a new Em4 valve and metering design Jesse built on Friday, and it worked.
