This visualization of Japan’s M6.8 yesterday is phenomenal. Offshore S-net detected it and issued earthquake alert before any land station detection. Numbered circles show JMA intensity (not same as MMI). Offshore is where we need to be in Cascadia as well.
The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku.

Edinburgh is a wonderful city. And it is generally accessible, however as with any city, some parts are more accessible than others. This map uses data from ArcGIS Online to show the accessibility score by postal codes.

Vince Guaraldi’s "The Great Pumpkin Waltz" is now #1 on the iTunes US song chart. A 1966 jazz classic shows Linus was right — the Great Pumpkin always delivers.
