Muma1950, yaishandiswa sedanda rekurasa regirazi rakatsvuka, uyezve chirimwa chakavharwa, zvichisiya makumi ezviuru emabhodhoro egirazi akasara, makore makumi matanhatu apfuura
Mune mamwe makore zana kana zvakadaro, iyo mavara egirazi sand beas ichanyangarika, masayendisiti anoti. Nekuti mvura yegungwa uye mhepo yegungwa inoburukira pamusoro pegirazi, nekufamba kwenguva, girazi racho rakakwenenzverwa muchimiro chezvidimbu, ndokuuya mugungwa nemvura yegungwa, uye pakupedzisira inonyura kuzasi kwegungwa.
