2012-02-21 04:05:02 – Volcano Activity – Iceland

!!! WARNING !!!
EDIS Code: VA-20120221-34251-ISL
Date&Time: 2012-02-21 04:05:02 [UTC]
Continent: Europe
Country: Iceland
State/Prov.: Myrdalsjökull Glacier,
Location: Katla volcano,
City:  

Not confirmed information!
Description:

Volcanic tremor (a low frequency vibration often caused by magma rising to the surface) has been observed under Katla volcano in southern Iceland, Jón Frímann reports on his Iceland volcanoes blo, closely following seismic activity in Iceland recorded both by national instruments and his own private geophone network. According to Jón, there are 2 possible explanations: one could simply be an increase in hydrothermal activity in the northern part of Katla volcano. The second could be magma movements at depth although there have been no significant earthquakes that usually would accompany an intrusion or small (sub-glacial) eruption, although this still could occur in the near future as often observed in the past during similar episodes of tremor followed by earthquakes. The last minor eruption at Katla volcano was on 6 September 2011, and caused a small glacial flood.

Situation Update No. 5

Posted:2012-02-06, 05:45:32 [UTC]

Ref.no.: EQ-20120206-34066-PHL

Situation Update No. 5
On 2012-02-21 at 04:08:39 [UTC]

Event: Earthquake
Location: Philippines Central Visayas 8 km E Malusay

Number of Deads: 48 person(s)
Number of Injured: 56 person(s)
Number of Missing: 92 person(s)

Situation:

Philippine Institute of Volcanology and Seismology (PHIVOLCS) Director Dr. Renato U. Solidum Jr. confirmed yesterday that the 6.9 magnitude earthquake last Feb. 6 caused tsunami in some areas in Negros Oriental. “We have confirmed the occurrence of tsunami. It was localized. There were areas in Guihulngan and La Libertad that were hit by two to three meter waves. Areas that were far from the epicenter were hit by less than one meter waves. Even the other side of Negros and Cebu also experienced tsunami,” Solidum said. According to PHIVOLCS, in case of tsunamis that were locally generated, there will be not enough time for warning because they occur within a very short time. This year, the institute plans to further develop their system on earthquake, volcano and tsunami monitoring. “For tsunami monitoring, we have established a pilot PHIVOLCS designed system way back in 2007. Since we think it is already working well, we will improve it further and we will add more tsunami sensor,” Solidum added. PHIVOLCS plans to install a local based tsunami in Batangas, Manila Bay, Lingayen Gulf, Subic Bay and Albay Gulf so that the sensors can be tested.

Situation Update No. 1

Event: Volcano Activity
Location: Iceland Myrdalsjökull Glacier Katla volcano

Situation:

Iceland’s huge volcano Katla is stirring into life after tell-tale signs of the potential for an eruption were monitored by observers. A harmonic tremor has been recorded for two days and small earthquakes have been confirmed at the volcano by the Icelandic Met Office this morning. It is highly unusual for an eruption in Iceland to occur in the middle of winter but the early indications show Katla is building up power. Experts are unclear as to whether it is water or magma that is causing this week’s sudden increase in activity and the seismic recordings are currently lower than when the volcano first showed signs of a minor eruption last July. In September, Katla again stirred into life with a harmonic tremor and earthquakes in the volcano’s caldera – its magma chamber. Katla, which has not experienced a significant eruption for 93 years, is the second largest volcano on Iceland and the consequences of a major eruption will be felt across Europe. In 2010, the country’s president Ólafur Grímsson warned “the time for Katla to erupt is coming close, Iceland has prepared and it is high time for European governments and airline authorities all over Europe and the world to start planning for the eventual Katla eruption”. It is believed Katla, named after a vindictive troll of Viking folklore, has the potential to be much stronger and disruptive than the last two Icelandic volcanic eruptions that caused chaos across Europe’s air space, grounding flights and closing airports. Katla is much larger than its neighbouring Eyjafjallajokull – which erupted in 2010 – with a magma chamber about 10 times the size. Volcanologists warn that if Katla does erupt, the combination of the magma and the large ice sheet covering the volcano could lead to explosive activity and an ash plume for weeks, if not months.

United Kingdom – Enviroment Pollution – 2012.02.20

2012-02-20 17:14:46 – Enviroment Pollution – United Kingdom

!!! WARNING !!!
EDIS Code: ED-20120220-34250-GBR
Date&Time: 2012-02-20 17:14:46 [UTC]
Continent: Europe
Country: United Kingdom
State/Prov.: Scotland,
Location: Dounreay Nuclear Plant,
City:  

Damage level: Heavy (Level 3)

Not confirmed information!
Description:

Experts believe they may have found the most radioactive particle to be recovered so far from a beach near the Dounreay nuclear plant in Caithness. The Scottish Environment Protection Agency (Sepa) has been informed of the discovery at Sandside. Initial tests suggest it contained between one a two million becquerels (Bq) of radiation – at least twice as “hot” as a particle found in 2007. Additional monitoring is now being carried out at the beach. The particles are linked to the reprocessing of nuclear fuel rods at Dounreay during the 1960s and 1970s, when they were flushed into the sea through the plant’s liquid discharge pipe. The particle, which was found on 14 February, was the 208th to be recovered from the beach by contractors. Dounreay Site Restoration Limited (DSRL) said further analysis may confirm the find as “significant”. If so, it would be the first particle from Sandside to be given that classification. Initial tests estimated that an isotope called Strontium-90 in the particle had a radioactivity of between one and two million Bq. The most active particle found at Sandside so far was the one discovered in 2007 with a reading of 500,000 Bq. In March 2010, a particle containing 270,000 Bq was detected. A particle recovered from the seabed in 2010 contained 100 million Bq of radiation. DSRL has been leading a clean-up of the tiny fragments from beaches and the seabed near Dounreay. It said it had informed Sepa of the initial findings from the latest discovery and the need for additional tests to understand the chemistry of the particle and verify its potential hazard.
