Seizmometri (gr?. seismos - potres, graph? - pisati, bele?iti) su uređaji koji mjere pomicanje tla, uklju?uju?i seizmi?ke valove uzrokovane potresima , nuklearnim eksplozijama i drugim seizmi?kim izvorima . Bilje?enje seizmi?kih valova omogu?ava seizmolozima da naprave prikaz unutra?njosti Zemlje , odnosno lociraju i odrede efekte tih seizmi?kih izvora.

Osim izraza seizmometar se koristi i seizmograf , iako ponekad vi?e za starije uređaje u kojima su bilje?enje i mjerenje seizmi?kih valova vr?ili razli?iti mehanizmi.

Seizmometri i seizmografi se razlikuju od seizmoskopa koji je uređaj koji jedino bilje?i da je do do?lo do seizmi?kog vala, ne odaju?i podatke o njegovoj lokaciji i dimenzijama.

• Sean Morrisey's professional design of an amateur teleseismograph Also see Keith Payea's version Both accessed 2010-9-29 Morrissey was a professional seismographic instrument engineer. This superior design uses a zero-length spring to achieve a 60 second period, active feedback and a uniquely convenient variable reluctance differential transducer, with parts scavenged from a hardware store. The frequency transform is carefully designed, unlike most amateur instruments. Morrisey is deceased, but the site remains up as a public service.
