Ma geophones ndi zida zomwe zimasinthitsa kuthamanga kwa kayendedwe ka nthaka kukhala magetsi omwe amatha kugwiritsidwa ntchito kudziwa masanjidwe azinthu zomwe zili pansi padziko lapansi. Kuwona tsatanetsatane wa kapangidwe ka beseni kumafunikira malo ambiri azisangalalo omwe ali moyandikana kwambiri kuti athe kusintha kusintha kwakapangidwe kamtsinjewo. Zida zamagetsi zimapereka njira yotsika mtengo komanso yotheka yosonkhanitsira izi m'matawuni okhala ndi anthu ambiri, poyerekeza ndi zovuta komanso zolipiritsa zotumiza seismometers, Broadsa adatero.

Iliyonse mwa nkhokwe 202 zomwe zagwiritsidwa ntchito phunziroli, m'mizere itatu yoyambira mabeseni akumpoto, zili pafupi kukula kwa khofi. "Amalemera pafupifupi mapaundi sikisi ndipo amakhala ndi logger ya data, batri ndi zojambulira zonse mu chidebe chimodzi," adafotokoza Persaud. “Kuti tiwaike pansi timakumba kabowo kakang'ono kamene kangapangitse kuti malowa azikhala ndi nthaka pafupifupi mainchesi awiri akakhazikika bwino.

Ma node adasonkhanitsa deta mosalekeza kwa masiku 35. Pakadali pano, adazindikira zoyenda pansi kuyambira 6 ndi zivomezi zazikulu zomwe zidachitika makilomita masauzande ambiri kuchokera ku Los Angeles.

Ntchito zolandila zomwe zimawerengedwa kuchokera pamadontho a nodal ndizofanana ndi zomwe zimawerengedwa kuchokera ku data ya burodibandi, ofufuzawo adamaliza, koma gulu la nodal limapereka mawonekedwe owoneka bwino kwambiri monga malire pakati pa kutumphuka kwa dziko lapansi ndi chovala ndi mawonekedwe apakati mwala wapansi pansi pamabeseni.
