Hawaii: Crater of Hawaii Volcano Bulging, ‘What Happens Next is Anyone’s Guess’

07/12/2011 Leave a comment

“The bulging Pu`u `Ō `ō crater on the east rift zone of Hawaii’s Kilauea volcano is putting on a show, and there is no telling what could be next.

This USGS Hawaiian Volcano Observatory video shows a timelapse sequence taken from a thermal camera on the rim of Pu`u `Ō `ō crater.

The movie spans from May 26 to today and shows the rising level of the lava lake in the crater.

Things appear to be going slow in the first part of the movie, which shows the eruption during the month of June. You can see the level of the lava lake rises primarily due to overflows building the steep levee walls higher.

Scientists say sources within Pu`u `O`o crater are feeding that lava lake.

But its in the last portion of the movie where things get really interesting. From about July 1 to today, geologists say much of the rise of the lava lake has been due to uplift of the crater floor, carrying the lava lake upward. This uplift has been especially pronounced over the past few days, shown by the final few moments of the movie.” Read more.

Experts Keep Cose Watch on Vanuatu’s Increasingly Active Ambae Volcano

07/12/2011 Leave a comment

“Geohazard experts in Vanuatu have set up extra monitoring equipment around the increasingly active Ambae volcano.

A geohazard technical advisor with the Vanuatu government Sylvain Todman says nearby villagers are worried about the volcano’s increasing explosions and ash falls.

He says a team’s been dispatched to keep an eye on the volcano over the next week and seismic sensors have been set up on the east and west of the island.

‘It’s one of the most dangerous volcanoes on Vanuatu and there are many people around this volcano and the activity could increase very fast so we need to be as close as possible to notice any change in the activity.’

Sylvain Todman says the volcano’s level of activity may be upgraded from level one to level two which means people living within a five kilometre radius would have to move.” Source.

UK: Hundreds of Fish Found Dead at Scarborough Lake

07/12/2011 Leave a comment

“AS many as 200 fish have died at a Scarborough lake after being starved of oxygen.

The fish were left desperately gasping for air at Scarborough Mere after the lake’s oxygen levels plummeted following the recent weather.

Firefighters yesterday pumped gallons of water back into the site’s Match Lake to increase the air flow.

Environment Agency bosses confirmed the changeable atmospheric pressure was the cause with tests showing the lake’s air level was just 20 per cent oxygen after the heavy downpours.

In contrast, The Mere’s sister lakes had 132 per cent and 118 per cent oxgyen respectively.

Andy Maccalaugh, junior match secretary for Scarborough Mere Angling Club, said the lake would be closed for three days while water pumps – including one borrowed from Wykeham Lakes – worked to aerate the lake.

He said: ‘The fish were coming to the surface gasping for air.'” Read more.

Kansas – Hundreds of dead fish found at Arma City Pond – “ARMA — Hundreds of fish turned up dead in the Arma City Pond Friday morning. The kill is not unusual in the hot summer months, said District Fisheries Biologist Rob Friggeri, and he and his assistant, Logan Martin, scooped the dead fish out of the water Friday afternoon. What happens, he said, is that oxygen levels go down as the water heats up, which plays havoc with the fish. In the pond are grass carp, channel catfish, bluegill, largemouth bass and red-eared sunfish.” Read more.

Chile’s Puyehue Volcano Grounds More Flights in Uruguay and Argentina as Eruption Continues

07/11/2011 Leave a comment

“Clouds of ash spewing from Chile’s Puyehue volcano have grounded flights at airports in the capitals of Uruguay and Argentina, where a major football tournament is being held.

Scores of local and international flights were delayed or cancelled in and out of Buenos Aires, regional airport authority Aeropuertos Argentina 2000 said on its web page.

The Puyehue has been causing air travel mayhem since it rumbled back to life on June 4 for the first time in five decades, belching into the air a huge volume of dust and ash.

Flights across South America – including hubs in Montevideo, Chile’s capital city Santiago and southern Brazil – have been hard hit as ash clouds swept around the southern hemisphere to linger over Australia and New Zealand.

The flight disruptions on Friday wreaked havoc for football fans arriving in Argentina for the July 1-24 Copa America competition, which has been drawing thousands of supporters. The regional tournament is being played in several Argentine cities.” Read more.

“INDONESIA will evacuate hundreds of people living near Mount Lokon on Sulawesi island after raising the volcano’s alert status to the highest level.

‘We raised the volcano’s status to the highest red alert level last night,’ government volcanologist Kristianto told AFP.

‘There was a significant rise in volcanic activity since July 9. The volcano spewed ash 500m into the air over the weekend

Today we will be evacuating people living within a 3.5km radius around the volcano as a precautionary measure, in case of a bigger eruption which may be accompanied by deadly searing gas.’

Around 28,000 people live within the evacuation zone but only ‘hundreds’ will be moved today, those in the path of the ash, as officials continue to monitor volcanic activity, disaster management agency spokesman Sutopo Purwo Nugroho said.” Read more.

Iceland: Magma Appears to be Moving Beneath Hekla Volcano, Scientists Fear Eruption Soon

07/06/2011 Leave a comment

“Scientists are monitoring unusual underground activity that could signal an eruption at the Hekla volcano in southern Iceland.

University of Iceland geophysicist Pall Einarsson said Wednesday that magma appears to be moving deep beneath the volcano.

He says that does not necessarily mean an eruption is imminent.

But scientists expect Hekla, one of Iceland’s most active volcanoes, to erupt soon.

In the past few decades, Hekla has erupted about every 10 years, most recently in February 2000.

Iceland, in the remote North Atlantic, is a volcanic hotspot.” Read more.

‘Ring of Fire’ Volcano Erupts in Central Indonesia

07/03/2011 Leave a comment

“JAKARTA, Indonesia (AP) — A volcano in central Indonesia has erupted in clouds of smoke and searing gas that shot up nearly 20,000 feet (six kilometers) into the air.

State volcanologist Surono, who uses only one name, says no one was injured when Mount Soputan, located on Sulawesi island, exploded early Sunday.

The nearest villages are well outside the danger zone and there are no immediate evacuation plans.

Indonesia, the world’s largest archipelago, is located on the so-called Pacific ‘Ring of Fire,’ an arc of volcanos and fault lines encircling the Pacific Basin.” Read more.

Downpour Leaves 18-Metre Sinkhole in Ontario Highway

06/28/2011 Leave a comment

By ZEV SINGER – “A section of Highway 148 near Luskville, Ont., is now a canyon 18 metres deep, a victim of Friday’s heavy rains.

Remarkably, the family living next to the giant gap owns a construction company with expertise in exactly the type of work that will be needed to fix the road.

Not only does James Nugent, of R.H. Nugent Construction, have 35 years of experience in the field, he has the heavy machinery parked only a few hundred meters from the caved-in road.

‘We were called in right off the bat,’ he said. ‘There’s nothing signed, but we probably will be proceeding with the work under an emergency situation. They want a company that can start right away.’

Nugent said the large pipe that ran under that stretch of the highway seems to have been blocked at the intake. The torrents of water late last week stressed the situation causing the pipe to buckle and the ground above the pipe became waterlogged and gave way.

Since the initial cave-in, the canyon has grown wider, with landslides from the edge happening several times. He said it will likely happen again and people should stay clear of the edge by 10 meters on either side.

‘It could let go any time,’ he said.” Read more.

North Dakota: Officials Order Mandatory Evacuation of 12,000 Residents Immediately as Flood Waters Rise

06/22/2011 Leave a comment

By David Bailey – “(Reuters) – The emergency evacuation of one-quarter of Minot, North Dakota, residents was moved up several hours as a quickly rising Souris River threatened to swamp flood defenses, a city spokesman said on Wednesday.

Minot officials had ordered a mandatory evacuation for up to 12,000 residents of the city, North Dakota’s fourth largest, by 6 p.m. on Wednesday, but rising river waters were expected to top some levees by late morning.

‘It’s imminent,’ Dean Lenertz, a Minot Fire Department captain and spokesman, said of the sounding of emergency sirens to start the evacuation.

‘We are trying to patch up as many holes as we can to give people as much time as we possibly can to get them out safely.’

A warning on the Minot city website said the National Guard had identified ‘several areas of concern’ in flood-threatened areas of the city.

‘It is imminent that the flood sirens will be sounding …People should gather the final items that they want to take and evacuate the evacuation zones.'” Read more.

US: Hundreds Of Dead Fish In River Des Peres, Missouri

06/22/2011 Leave a comment

By Roche Madden – “ST. LOUIS, MO (KPLR)—Hundreds of dead fish are floating in the river Des Peres in South St. Louis. The state has investigated to determine if it was caused by man or nature.

Neighbors who live around the river told News 11 they first spotted the dead fish floating in the river on Wednesday. Hundreds of dead fish stretch for more than a half mile North of Gravois. MSD owns the section of the river. They say they hired crews to spray weed killer and they double checked today and say the crews did use a chemical that does not threaten wildlife. Conservation experts say when the rising Mississippi backs up into the river Des Peres the water can stagnate, lose the oxygen and the fish die, a disturbing sight to people who live nearby.

‘I think something’s wrong something disturbing because there shouldn’t be dead fish floating everywhere.’ said Kathy Shaver.” Read more.

Bali: Volcanic Lake Batur Suddenly Changes Color, Massive Fish Die Off Ensues

06/22/2011 Leave a comment

“A unusual natural phenomenon is causing concern for communities living around the edge of Bali’s Lake Batur at Kintamani.

On Sunday, June 19, 2011, the waters of the lake that sits in a volcanioc crater suddenly changed colors to a whitish-blue shade followed by the sudden death of thousands of fish (tilapia) living in the lake.

According to NusaBali, villagers for the lakeside community of Lintang Danu recount that the lake suddenly changed color on Sunday (June 19) morning in the areas surrounding the villages of Songan. Batur, Kedisan and Buahan. Shortly after the color change, thousands of freshwater fish floated to the surface and begin washing up on the lake’s shore. Fish farmed by villages in the shallows of the lake also died with the changing color of the lake.

Local fisherman, who traditionally plant local freshwater majiar fish (tilapia) in the lake, scrambled to the location to rescue fish in distress but still alive to place them in fresh water pools ashore.

The head of the Wildlife and Fisheries Service for the regency of Bangli, A.A. Ngurah Shamba, said his office was still surveying the situation and trying to understand the natural phenomenon that change the water color and caused the fish die-off. Samples of dead fish have been collected for laboratory analysis.” Read more.
