It's Geologic Map Day! Geology and Maps, what could be better! Below is a Geologic Map of the Brevard fault in North Carolina.

The USGS has posted a focal mechanism solution for the M7.3 Alaska earthquake. These are based on seismic observations and can identify the type of Earthquake, but they show two possible fault orientations, one of which is real. This one shows an E-W and NW-SE fault. #geology

A 7.3 Magnitude earthquake recently occurred in the Alaskan forearc west of the Shumagin Islands. The aftershock sequence appears to trend mostly east-west suggesting a fault in that orientation. #earthquakes #Geology @EcuGeology

Here is another A. Gaudi building in Barcelona: Casa Batllo. It is a unique and organic take on modernism. #architecture #Barcelona

Here is the Sagrada Familia Cathedral in Barcelona, Spain. It was designed by Gaudi and has been under construction for the past 140+ years. #Barcelona
