So Close, Yet So Far…

LCHO, our new seismic station, has been transmitting data to headquarters in Delaware, Ohio for less than a week. It will be some time before the new stations go online. Still, the earth never sleeps.

This is an image from the BGSO station at BGSU in Bowling Green, Ohio.

It will take you some time to sort this out…Each hour has four colors marking 15 minute intervals.  Black is the first 15 mintes, red the second 15minutes (up to 30), green is the third 15 minutes(up to 45)and blue is the last 15 minutes of the hour.

The disruption you see passed under BG just after 0:06 UTC or 6 minutes after midnight Sunday 4/17/2016. See how the first scribbles are the black ones, even though the red ones are bigger? That is UTC (Universal Time) which converts to 20:06 or 8:06PM EDT on 4/16/2016.aBGSO-1ZIP2016.


The red waves are so large, they are “clipped” in this image.

So, where was this earthquake?

Ecuador…It hit at 6:58PM local time.  The little turquoise dot is one of the many aftershocks. The big one is the larger orange “bottom” dot.

You can read more about this quake in BBC NEWS.

The shock waves from the first quake made to BG in 8 minutes and lasted around 3 hours and 18 minutes! HOW IS THAT POSSIBLE? Remember the waves keep traveling around the planet like ripples on a pond…..Only our little “pond” is round and as they say…

“What goes around, comes around”.
