Supertyphoon Haiyan, which battered the Philippines in November 2013, was the most powerful hurricane to make landfall ever recorded.
One recent study suggested behemoths like Haiyan, which had maximum sustained winds of about 310 kilometers per hour, might warrant the creation of a new hurricane classification, ?Category 6.? In addition to the thousands of deaths and casualties, flattened homes and widespread debris, Haiyan left other, less visible signs of damage in its wake, including to the fragile coastal aquifers that many residents rely on as their sole source of drinking water. Now, a new study has quantified damage done to these environmental resources, and how long it might take for them to recover.
