Earthquake swarm under La Cumbre volcano, La Palma, Canary Islands

Locations and depth vs time plot of yesterday's quakes under La Palma

Locations and depth vs time plot of yesterday's quakes under La Palma
A relatively strong earthquake swarm occurred under the La Cumbre volcano on La Palma Island yesterday (24 Dec 2020).

A total of 79 small quakes of magnitudes between 1-2.2 were detected during yesterday, most of them at depths around 25-30 km under the southwestern part of the island, 15 km southeast of Los Llanos de Aridane.

Many are located under the mostly submerged volcanic ridge of Cumbre Vieja, which last erupted in 1971.
It seems that the swarm has already ended (unless more data will be released by the Spanish Geophysical Insitute later on).

4 earthquakes recorded in 24 hours on Mayon Volcano, Philippines

Mayon Volcano
Four earthquakes were recorded in the vicinity of Mayon Volcano in the last 24 hours as it remained under Alert Level 1 status, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Saturday.

"Mayon Volcano's monitoring network recorded four (4) volcanic earthquakes during the 24-hour observation period," state volcanologists said in a statement.

Phivolcs, likewise, noted that there is "moderate emission of white steam-laden plumes that crept downslope" on the volcano.

Phivolcs also reminded residents living near the volcano to be vigilant because it is still at abnormal condition.

Cracked mountain in Alps may collapse any time, researchers warn

Hochvogel, a nearly 2,600-metre summit in the Allgäu Alps, where the national border between Germany and Austria runs, has long been known to be divided by a huge fracture that continues to grow from year to year.

A team of researchers has worked out certain regularities in the tectonic movements in the area around the mountain Hochvogel in the Alps.

In particular, they arrived at an effective method of monitoring a giant fracture that cuts through the 2,592-metre-high summit. It is called a seismic approach, and with the help of it, "we can now for the first time sense, record and process this cyclical phenomenon continuously and almost at real time", says Michael Dietze, the lead author and post-doctoral researcher at the GFZ Helmholtz Centre Potsdam.

Russia's Hydrometeorological Center has forecast that Western and Central Siberia will see temperatures as low as -50 celsius before the end of the year - around 20 degrees lower than the typical December cold.

Earlier this year, in the height of summer, the highest-ever temperature seen above the Arctic Circle was recorded, with the small town of Verkhoyansk seeing the mercury reach as high as +38.

MEC Hlomuka has also expressed his concern at the increasing number of incidents where lightning strikes kill people in the province.

Parents of a six-month-old baby lost their lives in eManyiseni under uMhlabuyalingana Municipality in Northern KZN, when lightning struck their home on 23 December.

In a separate incident in Jozini ward 15 in the Ndabeni area, a 70-year-old man was fatally injured after being struck by lightning.


Inclement weather conditions continue to wreak havoc across rural KZN communities.

An earthquake of magnitude 6.3 struck the Mindoro region of the Philippines, the European Mediterranean Seismological Centre (EMSC) said on Friday. The earthquake occurred at a depth of 144 km (89 miles), EMSC said.

The earthquake, which was also felt in the capital region of Manila, also registered at magnitude 6.3 at the Philippine Institute of Volcanology and Seismology (Phivolcs).

The earthquake centre was traced at Calatagan in Batangas province, according to an initial report from Phivolcs, which said it did not expect damage but warned of aftershocks.

It issued no tsunami warning after the earthquake.

Rare blizzard warning for Twin Cities

Golden Valley, Minn. — Blizzard warnings issued by the National Weather Service yesterday in the Twin Cities metro were a rare occurrence. A blizzard is when visibility is less than 1/4 of a mile for 3 hours or more, due to falling or blowing snow. White-out conditions covered the state, along with the metro.

The last blizzard warning that included the Twin Cities was only two years ago, April 14th, 2018. However, the one before that was the famous Halloween blizzard back in 1991. Let's look back even a little further, to another blizzard event back on April 14th 1983.

Why are blizzard warnings rare for Minneapolis and St Paul? This is due to the urban influence. Warmer temperatures are typical in cities due to the presence of lots of metal, and urban areas usually have less moisture and less vegetation.

Chiba Prefecture announced Thursday an outbreak of avian influenza believed to be highly pathogenic at a chicken farm in the city of Isumi in the eastern Japan prefecture.

Since November, farm outbreaks of such bird flu have occurred in 12 prefectures, including the western prefecture of Kagawa and the southwestern prefecture of Miyazaki. Chiba is the 13th prefecture to report an outbreak this year and the first to do so in eastern Japan.

Chiba has the second-largest number of farmed egg-laying hens in the country, after Ibaraki Prefecture, also in eastern Japan.

Comment: This is just the latest issue to hit food producers and one wonders just how much more the food supply can take before significant food shortages begin to be felt:
