Winds, fire, floods and quakes: We’ve seen a nutty run of nature

- By Seth Borenstein AP Science Writer

WASHINGTON — With four big hurricanes, a powerful earthquake and wildfires, it seems that nature recently has just gone nuts.

Some of these disasters, like Friday’s earthquake in Mexico, are natural. Others may end up having a mix of natural and man-made ingredient­s after scientists examine them. We also always tend to look for patterns and order in chaos, even when they aren’t there, psychologi­sts say.

“Nature’s gone crazy,” mused Jeff Masters, meteorolog­y director at the private service Weather Undergroun­d. “Welcome to the future. Extreme weather like this is going to be occurring simultaneo­usly more often because of global warming.”

A look at a rough few weeks in North America:

Hurricane quartet

hadn’t Hurricanee­ven fizzled Harveyand Houston hadn’t even dried out from record flooding before Hurricane Irma formed and also grew into a powerful Category 4 storm. Right behind Irma, Jose has powered up to a Category 4 storm.but not It is unpreceden­tedhighly unusual, to have back-to-back storms of that strength, Masters said. And then there is Hurricane Katia, just a shade under major hurricane status, due to hit Mexico’s Gulf coast.

The last couple of years were quiet for Atlantic hurricanes, which makes this year seem even worse, said Colorado State University meteorolog­y professor Phil Klotzbach, a hurricane expert. He said calculatio­ns that measure strength and duration show the three current Atlantic storms set a one-day record for energy on Friday. In just three days, Irma, Jose and Katia have produced as much as energy as about half a normal six-month hurricane season.

Earthquake

As Mexico was bracing for Katia off the Gulf coast, one of the strongest earthquake­s in the country’s history hit late Thursday off its Pacific coast, near the Guatemala border. The magnitude 8.1 earthquake was felt for more than 650 miles (1,000 kilometers). The quake shook at a depth of and depth43 a miles quakewith that(69 hitting kilometers)strengthat thatis unusual, according to Cornell University geophysics professor Geoff Abers. It was one of the five largest for that deep in the past 40 years, he said.

Wildfires

On Friday, 82 wildfires were burning in the United States involving nearly 1.5 million acres in nine states in the West. So far this year, more than 8 million acres have burned, only behind 2015 and 2012. One fire at the Rogue River-Siskiyou National Forest in Oregon has burned more than 175,000 acres and is only 5 percent contained as of Friday, according to the National Interagenc­y Fire Center.

What’s going on here?

Sometimes there’s a pattern in chaos. Sometimes there isn’t. Looking for patterns gives us a sense of control, even if we don’t really have it, said Scott Lilienfeld, a psychology professor at Emory University in Atlanta. It can take weeks or months for scientists to determine whether an extreme weather event was worsened by man-made climate change.
