People in Guam and the Northern Marianas moved to emergency evacuation centres and made last-minute preparations on Sunday, hours before a “super typhoon” was projected to bulldoze through the US Pacific territories. Super Typhoon Bavi was forecast to roar westwards over the area from early Monday with winds of 260 kilometres per hour – equivalent to a category 5 hurricane – and gusts of up to 315 kph. The US National Weather Service called the weather event “very dangerous”, warning of “tropical storm force” winds from Sunday afternoon or evening and “catastrophic” damage near the system’s centre later. Do you think that the typhoons are due to human activities inside or around the ocean ?
