Lava Flow Increases at Pacaya Volcano in Guatemala

The effusive-explosive eruption of the volcano continues.

The lava flow on the southwestern eruptive fissure has increased in length, currently about 525 m long.

Weak-to-moderate strombolian-type explosions continue from the Mackenney summit crater with ejecta thrown at an approximate height of 20 and 50 meters.

The seismic instruments recorded internal tremor associated with explosions and lava flow and magma rising within the volcano edifice.

Thousands of fish destroyed after massive landslide strikes Alaska

Landslide Danger Alert

One of the largest salmon hatcheries in the state was forced to destroy thousands of fish after a landslide Wednesday damaged a pipeline that supplies its water.

The Macaulay Salmon Hatchery in Juneau is run by Douglas Island Pink and Chum Inc., known locally as DIPAC. Its water comes from Salmon Creek Reservoir and shares a pipeline with Alaska Electric Light & Power’s power plant.

Debris from the slide and others along Salmon Creek road caused by heavy rain makes it difficult to access the area. That means it will take some time to repair the pipeline

Without a freshwater source, the hatchery’s staff had to make a tough decision over which fish to save with the remaining water.

They destroyed all the young chinook salmon and rainbow trout that would have been released next spring, and most of the young coho salmon, too.

The rest of the facility’s fish stock is stable for now. The hatchery is working with AEL&P to secure a backup water supply until the pipeline can come back on line.

The Salmon Creek trail remains closed while AEL&P makes repairs.

The hatchery has been operating in its current location since 1990, according to its website. It’s permitted for 135 million chum, 1.5 million coho, 1 million chinook and 50,000 rainbow trout. It can hold up to 300 million eggs and is one of the eight largest salmon hatcheries in the State of Alaska.

91 reports of landslides, fallen trees in Tobago since November

Landslide Danger Alert

In October and November, Tobago had 91 reports of landslides and fallen trees associated with bad weather, according to the Tobago Emergency Management Agency (TEMA) director Allan Stewart.

He said this has been the most landslides recorded in Tobago over the last ten years.

Speaking to Newsday on Wednesday Stewart said, “Every single weekend we have been having heavy rainfall and this brought us to this episode of landslides. Even without rain we are still having landslides because of the amount of water in the soil, and the slopes are unstable right now.”

On Tuesday TEMA received another report of a landslide in Castara threatening the home of one family.

He said many of the homes were constructed on hills without a retaining wall.

“It now costs more to build the retaining walls than the value of the homes. In some cases, the house is less than $40,000, and to protect that same property is close to $1 million. Retaining walls are expensive. But it’s our best chance to protect these homes and families.”

He said in November there were over 36 reports of landslides. Twenty-eight of them were classified as “severe,” affecting several villages in Tobago East.

“TEMA’s response to the landslides went quite well. There was some delay as a result of the mobilisation and the time of the occurrence.

“Some of these reports were domestic and required more attention.”

He said two families, in the Parlatuvier area, were advised to leave their homes after a landslide covered the buildings.

“If there is additional rain it now puts the homes at greater risk, so they were asked to evacuate. These homes are small – one-bedroom, toilet and bath – that’s being pushed away by the landslides. From preliminary investigation, they would have to rebuild their homes.”

He said TEMA has been receiving assistance from the Division of Infrastructure, Quarries and the Environment and the fire and police service.

In a recent release, the Met Office said December is likely to be wetter than usual. December 2020-February 2021 is likely to have above-average rainfall with an 80 per cent chance of at least one seven-day wet spell.
