Don't know about seismic, but it appears to have shown up on infrasonic:

*PERUVIAN METEORITE UPDATE: *On Sept. 15th, a fireball streaked across 
the skies of Peru and soon thereafter a watery crater 
<http://www.spaceweather.com/swpod2007/08oct07/crater.jpg> was 
discovered by local residents near the town of Carancas. At first 
experts dismissed the connection; the crater didn't look like a 
meteorite impact. But since then minds have changed:

"Without reservation this is definitely a meteorite," says
astronomy professor Peter Brown of the University of Western Ontario. 
"We found some infrasound <http://aquarid.physics.uwo.ca/infrasound.htm> 
data recorded by a station in La Paz about 70 km away. From the size of 
the the airwave we can work out the kinetic energy of the 
impactor--about 0.03 kton TNT."

"Something like 20 to 30 kg of the meteorite have already been 
recovered, but odds are good a multi-ton monster lurks at the bottom of 
the crater," he continues. "The bad news: It is below the water table, 
the rainy season is coming and unless some action is taken ASAP, the 
rock will quickly oxidize and crumble." [more

Meanwhile, he says, "we are digging for seismic data of the actual 
impact--the first actual seismic recording of a terrestrial meteorite 
impact!" Stay tuned.
