Best of the Web: New Zealand: Threat of Earthquakes Pales Beside The 50 Volcanoes on Our Doorstep

It hardly needs an official list from the council to remind Aucklanders that, like Christchurch, this city is peppered with old buildings that are likely to tumble down in a severe earthquake.

The main arterial roads through well-established suburbs such as Newmarket, Herne Bay, Mt Eden, Dominion Rd, Onehunga and Otahuhu all have clusters of 100-year-old, two-storey brick retail premises, shops downstairs, dwellings above.

In the CBD, old masonry buildings provide the "character" between the anonymous glass towers. Some have been strengthened, many not. The day after the Christchurch earthquake I emerged from a lunch bar in downtown Queens Arcade debating which side of the street would be safer to walk up if I succumbed to quake phobia.

Of course, venturing below the old harbour shoreline at Shortland St to the arcade was a bad move to start with. The old Auckland Regional Council's earthquake hazard guide warns that ground shaking would be greater in "reclaimed land such as parts of downtown Auckland".

This would also be prone to liquefaction, but only if the shake was "quite a large one", the guide says, helpfully adding that in Auckland there is "a 10 per cent chance of [that] occurring in the next 50 years".

As well as buildings falling on you and silt squirting up your trouser legs at that end of town, there's the added risk of death by tsunami.

Hawaii: Lava spews 65 feet high after crater collapse

Kilauea, Volcano

Scientists say the Pu'u O'o crater floor has collapsed and an eruption occurred along the middle of Kilauea Volcano's east rift zone. Scientists at the Hawaiian Volcano Observatory say after a fissure broke out around 5 p.m. Saturday, lava was seen erupting up to 65 feet high.
A new vent has opened at one of the world's most active volcanoes, sending lava shooting up to 65 feet high, scientists at Kilauea volcano said Sunday.

The Hawaiian Volcano Observatory said the fissure eruption was spotted shortly after the floor at the Pu'u O'o crater collapsed around 5 p.m. Saturday. It occurred along the middle of Kilauea's east rift zone, about 2 miles west of Pu'u O'o.

"As a volcanogist, this is what we do. These are the moments we wait for," volcanogist Janet Babb told KHON2. "It is exciting to see an eruption begin particularly if you can see it from the very start."

Iceland: Earthquake Activity Increases Again in Krýsuvík Volcano

It appears that Krýsuvík volcano earthquake activity is increasing again. This time around it appears that the earthquake activity in Krýsuvík volcano has moved more to the west then last weeks earthquake activity.

The biggest earthquake so far is a ML2.1 earthquake with the depth of 6.9 according to automatic data on Icelandic Met Office web page.

Japan: 50 Melon-Headed Whales Stranded on Ibaraki Shore; 22 Rescued

Mito - About 50 melon-headed whales were found to have beached on the shore in Kashima, Ibaraki Prefecture, in eastern Japan Friday night and 22 were rescued and returned to the sea on Saturday by authorities and local volunteers.

About 200 people, including staff at Oarai Aquarium in the same prefecture, city government officials and local residents and surfers near the Oritsu coast tried to save the beached whales by keeping them hydrated while they tried to refloat them, but 30 of them died, according to the city government.

It took about eight hours to return the surviving whales to the sea, the officials said, adding they have buried the carcasses of the dead whales on the nearby shore.

Melon-headed whales are commonly seen offshore around the area in the early spring and they may have been drawn into the shallow waters while following their food, said Masayuki Shimada, chief of the marine animal exhibition section of the aquarium.

First Look at New Volcano Fissure Erupting in Hawaii

New fissure eruption

The geologists with the USGS Hawaiian Volcano Observatory have released a first look at the new fissure eruption that just started today between Pu'u 'O'o and Napau Crater.

According to geologists, the first portion of the video was shot from the air looking southwest at the fissure eruption between Pu'u 'O'o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can't be picked out at this distance.

The second part of the video was shot from the ground in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.

US: Mom sheltering child dies as tornado hits Louisiana town

Rayne, Louisiana - When the tornado hit this Louisiana town, Jalisa Granger was instinctively sheltering her child from the sudden, fierce winds. Pieces of homes shot skyward, debris lodged in treetops and a U.S. Postal Service truck was flipped on its side.

When it was over, the 21-year-old mother lay dead from a tree that had fallen on top of her home, authorities say. But her child survived the tornado's rampage through Rayne, a south Louisiana community of 8,500 people some 70 miles west of Baton Rouge.

Maxine Trahan, a spokeswoman for the Acadia Parish Sheriff's Office, said Granger was protecting her child when the tornado hit.

"She sheltered the child to protect her from the storm and a tree fell on the house and it killed the mother but the child was OK," Trahan said. A relative who lived nearby found the woman.
