Ua ʻōlelo ka Pelekikena o Peru e kākoʻo kāna aupuni i ka poʻe i hoʻopilikia ʻia e ke ōlaʻi 7.5-magnitude o kēia kakahiaka i ke kakahiaka nui o ka Lāpule, e waiho ana i ka pōʻino i ka ʻaoʻao ʻākau o ka ʻāina.
Eia kekahi, ua hoʻopaʻa ʻia kahi ōlaʻi 5.2 ma Lima, ke kūlanakauhale nui o Peru.
ʻAʻohe hoʻoweliweli kai eʻe no ka Moana Pākīpika.
ʻAʻole ʻike ʻia ka ōlaʻi ma kahi mamao o Peru ʻĀkau. ʻAʻohe mea i hōʻike ʻia he poino, akā ua pōʻino nā hale a me nā alanui, e like me ka ʻike ʻia ma nā wikiō i hoʻouka ʻia e ka Pūʻali Makai Lahui o Peru.
Ua ʻike ʻia ke ōlaʻi ma ʻEkuador a hiki i Lima.
ʻO ka lā 28 Nowemapa, 2021, M 7.5 ʻĀkau Peru ʻo ke ōlaʻi ma muli o ka hāʻule maʻamau ma kahi hohonu waena, ma kahi o 110 km ma lalo o ka ʻili honua i loko o ka lithosphere i hoʻohaʻahaʻa ʻia o ka pā Nazca. Hōʻike ʻia nā hoʻonā ʻenehana kikoʻī ua ʻāhaʻi ʻia ma ke komohana ʻākau a i ʻole hema-hema hikina e hahau ana, e hōʻemi ana i ka hewa maʻamau.
Ma kahi o ke ōlaʻi, neʻe ka pā Nazca i ka hikina pili i ka ʻAmelika Hema ma kahi wikiwiki o 70 mm / yr, subducting ma ka Peru-Chile Trench, i ke komohana o ke kahakai Peruvian, a me ka lā 28 o Nowemapa. ōlaʻi. ʻO nā ōlaʻi o ka ʻākau o Peru a me ka hapa nui o ke komohana o ʻAmelika Hema ma muli o nā pilikia i hana ʻia e kēia hoʻoiho ʻana; ma kēia latitu, ua ikaika ka pā Nazca a hiki i ka hohonu o 650 km. Ua ōlaʻi kēia ma kahi ʻāpana o ka pā i hoʻohaʻahaʻa ʻia i hana i nā ōlaʻi pinepine me ka hohonu o 100 a 150 km.
ʻO nā ʻōlaʻi e like me kēia hanana, me ka hohonu o ka hohonu ma waena o 70 a me 300 km, ua kapa ʻia ʻo ia he "ʻōlaʻi waena-hohonu". Hōʻike nā ōlaʻi waena-hohonu i ka hoʻololi ʻana i loko o nā papa i hoʻohaʻahaʻa ʻia ma mua o ka pā pāpaʻu pāpaʻu ma waena o ka hoʻohaʻahaʻa ʻana a me nā papa tectonic. Hoʻemi pinepine lākou i ka pōʻino ma ka ʻili honua ma luna o ko lākou foci ma mua o ke ʻano o nā ōlaʻi pāpaʻu like ka nui, akā hiki ke ʻike ʻia nā ōlaʻi nui waena-hohonu ma kahi mamao loa mai ko lākou mau kikowaena.
He mea maʻamau nā ōlaʻi waena-hohonu nui ma kēia ʻāpana o ka pāpaʻi Nazca, a ʻelima mau hanana waena waena M 7+ i hana ʻia i loko o 250 km o ke olai ʻo Nowemapa 28 i ke kenekulia i hala. ʻO ke olai AM 7.5 i ka lā 26 Kepakemapa 2005, aia ma kahi hohonu like akā ma kahi o 140 km i ka hema o ke ōlaʻi ʻo Nowemapa 28, 2021, ua make 5 mau make, ma kahi o 70 mau ʻeha, a me nā pōʻino nui ma nā wahi a puni. ʻO ka mea hou aku nei, he ōlaʻi M8.0 ma Mei 26th 2019, ma kahi o 230 km i ka hikina hikina o ke ōlaʻi ʻo Nowemapa 28th 2021, ua hopena i 2 mau make.
He aha e lawe ʻia mai kēia ʻatikala:
- At the location of the earthquake, the Nazca plate moves to the east relative to the South America plate at a velocity of about 70 mm/yr, subducting at the Peru-Chile Trench, to the west of the Peruvian coast, and the November 28th earthquake.
- Large intermediate-depth earthquakes are reasonably common in this section of the Nazca slab, and five other intermediate-depth M 7+ events have occurred within 250 km of the November 28th earthquake over the past century.
- 5 earthquake on September 26th 2005, located at a similar depth but approximately 140 km to the south of the November 28th, 2021 earthquake, caused 5 deaths, about 70 injuries, and significant damage in the surrounding region.
