M\u0103 uitam la c\u00e2teva clipuri cu dezastrul din Turcia. Blocuri pe cadre de beton care se pr\u0103bu\u0219esc \u00een secunde. <\/p>\n\n\n\n

Sigur, energia disipat\u0103 de un cutremur de 7.8 – 7.9 e enorm\u0103. Exist\u0103 discu\u021bia cum “coaie, tu nu \u00een\u021belegi scala logaritmic\u0103 \u0219i cum un cutremur de 7 grade Richter e de 10 ori mai puternic dec\u00e2t unul decat unul de 6”. O inteleg \u0219i nu e, sau nu neap\u0103rat. Ca magnitudine, da. Ca energie disipat\u0103, da. Efectele nu sunt propor\u021bionale cu energia eliberat\u0103 ci cu amplitudinea, frecven\u021ba \u0219i durata de manifestare , e treab\u0103 de rela\u021bie dintre amplitudinea \u0219i frecven\u021ba undelor \u0219i energia la care se produc. <\/p>\n\n\n\n

In fine, ce vreau s\u0103 zic e c\u0103 majoritatea construc\u021biilor din majoritatea \u021b\u0103rilor nu sunt proiectate s\u0103 reziste la un cutremur catastrofal, c\u0103 de aia ii spune catastrofal. Nu numai c\u0103 nu sunt proiectate s\u0103 reziste , dar nu sunt proiectate nici m\u0103car s\u0103 protejeze via\u021ba oamenilor din\u0103untru in caz c\u0103 se d\u0103r\u00e2m\u0103. <\/p>\n\n\n\n

V\u0103d asta ca pe o problem\u0103. Construc\u021bia ia \u00een calcul probabilit\u0103\u021bi. Dac\u0103 via\u021ba planificat\u0103 construc\u021biei este de 50 de ani \u0219i \u00een 50 de ani \u0219i un risc de 10% de ap\u0103rea un eveniment care s\u0103 o d\u0103r\u00e2me, pare acceptabil . Anual, riscul este de 0.2% Pentru at\u00e2ta lucru faci \u0219i tu o asigurare. Exist\u0103 asigur\u0103ri \u0219i de via\u021b\u0103. Ce pula noastr\u0103. <\/p>\n\n\n\n

Nu e ca \u0219i cum nu putem construi astfel \u00eenc\u00e2t s\u0103 nu se d\u0103r\u00e2me \u0219i punct. Putem , dar este definit ca ne-economic. <\/p>\n\n\n\n

Argumenta\u021bia este c\u0103 oricum , \u00eentotdeauna poate s\u0103 fie un cataclism mai mare, nu po\u021bi construi pentru riscuri infinite, c\u0103 nu e rezonabil. E rezonabil s\u0103 mai \u0219i mori. <\/p>\n\n\n\n

Chiar este. M\u0103 uit la casele din UK. Dac\u0103 m\u00e2ine o s\u0103 fie un cutremur de 7 grade aici o s\u0103 \u00eemi pice c\u0103r\u0103mizile in cap, cred. Pe de alt\u0103 parte aici nu au fost seisme de 7 grade de dracu \u0219tie c\u00e2nd. Nu-i bai, c\u0103 \u0219i dac\u0103 o s\u0103 fie unul de 6 o s\u0103 moar\u0103 oameni. S-a mai \u00eent\u00e2mplat \u0219i la magnitudini mai mici. <\/p>\n\n\n\n

Astora le pica ferestrele la 4.5 \u0219i sar pe geam, iar la peste 5 zboar\u0103 tencuiala \u0219i buc\u0103\u021bi de ziduri.<\/p>\n\n\n\n
