Last night around midnight there was a pretty loud "boom" (sounded like a rocket or motor hitting a couple kilometers away) followed shortly by the ground shaking for about 1 second (windows rattled). I hadn't been drinking and everyone else on the property heard and felt it as well...so not just me . I checked Seismological Observation and Ea but nothing in the area around that time. Anyone else up in Valencia here/feel this? Given the very short duration of the ground shaking I'd think it was an explosion.
