In the last two weeks, more than 100 mostly tiny earthquakes a day, on average, have rattled a remote area of Yellowstone National Park in Wyoming, putting scientists who monitor the park’s strange and volatile geology on alert.

Researchers say that for now, the earthquake cluster, or swarm — the second-largest ever recorded in the park — is more a cause for curiosity than alarm. The quake zone, about 10 miles northwest of the Old Faithful geyser, has shown little indication, they said, of building toward a larger event, like a volcanic eruption of the type that last ravaged the Yellowstone region tens of thousands of years ago.

The area is far from any road or community, and the park is relatively empty in winter. Swarms of small quakes, including a significant swarm last year, are relatively common.

But at a time when the disastrous earthquake in Haiti on Jan. 12 has refocused global attention on the earth’s immense store of tectonic energy, scientists say that the Yellowstone swarm, if only because of its volume, bears close observation: as of Sunday, there had been 1,608 quakes since Jan. 17.

“We’re not seeing a pattern that is really discernible yet,” said Henry Heasler, a coordinating scientist for the Yellowstone Volcano Observatory, a joint venture of Yellowstone, the United States Geological Survey and the University of Utah. Dr. Heasler said plans were in place to intensify observations in case the swarm continued for a long time or got larger. “We’re ready to ramp up,” he said, including using flights to monitor the area.

Researchers at the University of Utah’s Seismograph Stations who have tracked Yellowstone swarms said they thought it was coincidental that another big swarm of more 1,000 quakes had struck the park just over a year ago. At the time, it was the second-biggest cluster recorded there. The largest swarm was in 1985, when 3,000 earthquakes struck over three months.

Dreaming of biting into a garden-fresh cucumber sandwich this summer? Better order your seeds now.

A poor growing season last year and increased orders from Europe could make it difficult for home gardeners to get seeds for the most popular cucumber variety and some vegetables this spring. Farmers, who usually grow different varieties than home gardeners, aren’t likely to be affected.

Seeds for what’s known as open-pollinated cucumbers seem to be most scarce, but carrots, snap peas and onions also could be in short supply.

“I suspect there will be some seeds you just won’t be able to buy if you wait too long on it,” said Bill Hart, the wholesale manager in charge of seed purchasing at Chas. C. Hart Seed Company in Wethersfield, Conn. “The sugar snap peas we’re not able to get at all, and other companies that have it will sell out pretty quickly.”

The problem is primarily due to soggy weather last year that resulted in a disappointing seed crop. European seed growers also had a bad year, leading to a big increase in orders for American seeds.

Demand for seeds in the U.S. soared last year, as the poor economy and worries about chemical use and bacteria contamination prompted many people to establish gardens. Homegrown food seemed safer and more affordable. But some wonder if the wet weather that ruined gardens in many areas last summer will discourage first-time gardeners from planting again.

Everywhere he steered his skiff last week, Pete Frezza saw dead fish.

From Ponce de Leon Bay on the Southwest Coast down across Florida Bay to Lower Matecumbe in the Florida Keys — day after day, dead fish. Floating in the marina at Flamingo in Everglades National Park alone he counted more than 400 snook and 400 tarpon.

“I was so shook up, I couldn’t sleep,” said Frezza, an ecologist for Audubon of Florida and an expert flats fisherman. “Millions and millions of pilchards, threadfin herring, mullet. Ladyfish took it really bad. Whitewater Bay is just a graveyard.”

Fish in every part of the state were hammered by this month’s record-setting cold snap. The toll in South Florida, a haven for warm-water species, was particularly extensive, too large to even venture a guess at numbers. And despite the subsequent warm-up, scientists warn that the big bad chill of 2010 will continue to claim victims for weeks.

“Based on what I saw in 1977 and 1989, there is a good chance we’ll have a second wave,” said William Loftus, a longtime aquatic ecologist for Everglades National Park.

During those last two major cold fronts, weakened survivors succumbed to infections from common bacteria, such as aeromonas, that they would normally ward off, he said.

“It’s a nasty-looking thing,” he said. “It’s a tissue eater. It creates open ulcers on the side of the fish.”

A strong earthquake struck Haiti on Wednesday morning, shaking buildings and sending screaming people running into the streets only eight days after the country’s capital was devastated by a previous quake.

The U.S. Geological Survey said the 6.1 magnitude quake hit at 6:03 a.m. (1103 GMT) about 35 miles (56 kilometers) northwest of the capital of Port-au-Prince. It struck at a depth of 13.7 miles (22 kilometers) but was located too far inland to generate any tidal waves in the Caribbean.

Wails of terror rose Wednesday from frightened survivors of the apocalyptic quake that struck eight days ago as people as people poured out of unstable buildings.

It was not immediately possible to ascertain what additional damage the new quake may have caused.

Something to consider…

Aid workers hoping to distribute food, water and other supplies to a shattered Port-au-Prince are warning their efforts may need more security Friday as Haitians grow increasingly desperate and impatient for help.

United Nations peacekeepers patrolling the capital said people’s anger is rising that aid hasn’t been distributed quickly, and the Brazilian military warned aid convoys to add security to guard against looting.

“Unfortunately, they’re slowly getting more angry and impatient,” said David Wimhurst, spokesman for the Brazilian-commanded U.N. peacekeeping mission. “I fear, we’re all aware that the situation is getting more tense as the poorest people who need so much are waiting for deliveries. I think tempers might be frayed.”

During the southern hemisphere winter of 1983, temperatures at Russia’s Vostok research station in Antarctica plunged to a frighteningly cold minus 128.6 degrees Fahrenheit, which is 54 degrees colder than the winter average there and the coldest temperature ever recorded on Earth.

Scientists have now figured out why it got so cold.

For comparison, the coldest temperature ever recorded in the lower-48 United States was minus 70 degrees F (-57 degrees C) at Rogers Pass, Mont., on Jan. 20, 1954.

An explanation for why the mercury plunged precipitously during a 10-day period in July of 1983 (winter in Earth’s Southern Hemisphere) to that minus 128.6 F (minus 89.2 degrees Celsius) temperature has long eluded scientists.

A fierce earthquake struck Haiti late Tuesday afternoon, causing a crowded hospital to collapse, leveling countless shantytown dwellings and bringing even more suffering to a nation that was already the hemisphere’s poorest and most disaster-prone.

The earthquake, the worst in the region in more than 200 years, left the country in a shambles. As night fell in Port-au-Prince, Haiti’s capital, fires burned near the shoreline downtown, but otherwise the city fell into darkness. The electricity was out, telephones were not working and relief workers struggled to make their way through streets blocked by rubble.

In the chaos, it was not possible for officials to determine how many people had been killed and injured, but they warned that the casualties could be substantial.
