EARTH WEEK－A DIARY OF THE PLANET

　　Enduring Storms

　　Several more rounds of severe storms, tornadoes and flash flooding struck many parts of the American Midwest and Northeast as bad weather continued across the US for a second month.

　　Monsoon Storms

　　A south-west monsoon has caused havoc in parts of SriLanka. Government meteorologists said that unexpected monsoonal winds blew directly across the country from the Southern Hemisphere at about 100 km/h, producing several rounds of stormy weather. Nearly 250 houses in the capital Colombo were damaged.

For the week ending 3 July 1998

　　Mt. Etna Erupts

　　Sicily’s Mount Etna volcano erupted shortly after midnight on July 1, shooting“bombs”of lava nearly 1.5 metres in diameter on the eastern side of the mountain. The 30-minute eruption could be seen for several miles, but did not threaten any nearby villages.

　　Hurricane

　　Hurricane Blas lost strength as it moved over cooler waters in the Pacific Ocean to the west of Mexico. Blasformed off southwest Mexico during the previous week, but squalls on the outer fringes of the storm lashed western Michoacan State, killing four people when their wood and cardboard home collapsed.

　　Monkey Repellent

　　After years of unsuccessful attempts to keep crop-eating monkeys out of Japanese fields, a Tokyo research team believes that it may have finally found a way to prevent the damage caused by the monkeys. Animal raids on crops were successfully prevented by shooting chilli powder into the air, irritating the eyes and noses of monkeys that passed in front of carefully-placed warning sensors.“We’ve tried…all kinds of preventive measures, but the monkeys are smart enough to outwit the tricks,”said Toshiaki Wada, Director of the Tokyo Forestry Experiment Station in western Tokyo.
