Earth Changes
A magnitude 7.1 tremor shook buildings in Tokyo and a wide swathe of eastern Japan on Monday evening, triggering a small tsunami alert. NHK state television said it caused the off-site power supply for two damaged reactors to shut down.
The U.S. Geological Survey said the aftershock struck 38 km (24 miles) west of the city of Iwaki, at a depth of 13 km (8 miles).
Tokyo Electric Power Co (TEPCO), which operates the plant, said workers had stopped pouring cooling water on reactors No. 1, No. 2 and No. 3 at Fukushima.
Chief Cabinet Secretary Yukio Edano said villages and towns outside the 20 km (12 mile) evacuation zone that have had more accumulated radiation would be evacuated. Children, pregnant women, and hospitalized patients should stay out of some areas 20-30 km from the Fukushima nuclear complex, he added.

Etna has sprung back to life as April opens, with new eruptions from the Southeast Crater Cone. Friday and Saturday (April 8-9), the Italian volcano produced some ash and a 3-km lava flow, but then quieted. However, the seismicity under the volcano continued and late tonight into today (April 10), Etna starting producing small strombolian explosions from the Southeast Crater Cone (see below). You can check out a full description of the renewed activity on the INGV-Catania website (written by, surprise, Dr. Boris Behncke - be sure to follow him on Twitter for all sorts of updates). This is now the third eruption at Etna since the beginning of 2011. Eruptions reader Pgen Pgen also posted a timelapse of some of the April 9-10 activity at Etna.

Survivors in Miyako, Japan, observe a moment of silence in the rubble exactly a month after a massive earthquake and tsunami.
The 7.1-magnitude aftershock briefly forced Tokyo's main international airport to close both of its runways. The epicenter was just inland and about 100 miles north of Tokyo. The operator of the crippled Fukushima Daiichi nuclear complex said the latest quake had no impact on the plant.
A warning was issued for a three-foot tsunami, the same as for after an aftershock that shook the northeast coast last week. That quake generated no tsunami.
People at a large electronics store in the northeastern city of Sendai screamed and ran outside, though the shaking made it hard to move around. Mothers grabbed their children, and windows shook. After a minute or two, people returned to the store.

More than 2,000 people demonstrated in Tokyo on Sunday against the use of nuclear power in Japan.
A week before, a similar protest -- though in a chilly drizzle, not on a warm, sunny day -- drew about 250.
And a month of frustration, desperation and anger boiled over at Tokyo Electric Power Company's headquarters Friday as officials from towns around the Fukushima Daiichi nuclear power plant demanded to know when the crisis that has besieged their farming communities would end.
"The nuclear plant situation needs to be resolved as soon as possible. If not, we farmers will die," one of the officials, Iwao Suzuki, told the utility's executives.
But the response from Naomi Hirose, the managing director of Japan's largest utility, offered little encouragement to the delegation or the rest of the world.
The Texas Forest Service reported more than 60,000 acres burned and 40 homes lost in one blaze that raced through West Texas and into the small mountain town of Fort Davis. The fire rushed across 20 miles in 90 minutes.
Officials at the scene, however, estimated at least 100,000 acres in two counties had burned from the fire, which continued to grow Sunday evening.
"I can only describe it as an ocean of black, with a few islands of yellow," State Representative Pete Gallego said.

Flagstaff resident David Ellsworth took this photo in his front yard on S. Gila Dr. at 10 am on Saturday morning.
As of 10:30 am, the National Weather Service in Bellemont said it had so far received reports of 12 inches of snow in Grand Canyon Village, 10 to 11 inches in Flagstaff, 10 inches in Parks, 7 inches in Williams, 4.5 inches in Kachina Village and 4 inches in Doney Park. Sedona received an inch of snow all in one hour.
The Arizona Department of Transportation said that the I-17 North is closed between State Route 179 and Flagstaff because of the snow. ADOT is encouraging people to avoid driving unless necessary.
The twisters caused major damage to about 60% of Mapleton, a city of about 1,200 residents, Monona County Sheriff Jeff Pratt told reporters Sunday.
It was all part of a violent storm system that struck overnight, originating in eastern Nebraska and following a warm front across northern Iowa, according to National Weather Service meteorologist Frank Boksa.
But despite causing extensive damage, it did not lead to any fatalities, said Stefanie Bond, a spokeswoman for Iowa's Homeland Security & Emergency Management Division.
While the spring storm will initially lack the moisture coming up from the Gulf of Mexico, it will begin to produce strong thunderstorms from Texas through Illinois as it moves eastward later in the day and on Monday. These thunderstorms will have the potential of turning severe, with damaging wind, hail, and even possibly tornadoes.
Residents in the Southeast should monitor weather conditions due to approaching severe weather.
Only 77 people living near the crater of Taal Volcano left the island, a popular visitor spot 65 kilometres (40 miles) south of Manila, over the weekend, the National Disaster Risk Reduction and Management Council said on Sunday.
The island is home to 7,000 farmers, fishermen and tourist guides, according to the country's volcanology institute.
"We've had three storms come through, so I've run across a lot of scared customers," said Shaquan Hill, a clerk at the store. "It's not real safe for them to be out there right now."
Hill was telling nervous customers to stay put inside the store as the third storm began rolling through Gastonia just before 7 p.m., although not everyone was heeding her warnings.
"A lot of people just feel like they need to get where they're headed," she said.
