Associate Professor Ha Duyen Chau, a scientist at the Institute ofGeophysics , said that geomagnetic storms are expected to reach level5, the highest level, because the sun will reach the peak of its 11-yearcycle, putting the planet at greater risk of such storms between theend of 2012 and 2013.
Only 30 relatively weak storms hit the country last year, according to Chau.
Powerful geomagnetic storms could affect human health, particularlythose with a family history of heart disease, bone disease and thosevulnerable to geomagnetic storms, Chau said.
They might feel tired and experience bone-related pains, he added.
According to Chau, the national power grid and transformers may break down or sustain forage, resulting in blackouts.
Chau also said that the storms would be at their strongest at theaurora zones near the North Pole, South Pole and areas around theEquator. -VNA
