Volcanic Activity on the Rise
KAMCHATKA – The
Klyuchevskoy volcano, the highest active volcano in Eurasia, has
started erupting in Kamchatka, in the Russian Far East. The luminescence
over the volcano summit is evidence that glowing lava is flowing in
the crater. The volcano may start blowing out ash any moment now. The
Level of Concern Colour Code has been raised to Yellow, which is a
potential danger warning for aircraft. The giant volcano last erupted
from September 2009 to December 2010, and it began to again wake up in
June this year. Klyuchevskoy volcano is 4,750 meters above sea. –VOR
COLOMBIA -
According
to the Volcanological and Seismological Observatory of Manizales, an
earthquake measuring 2.6 on the Richter scale occurred yesterday at
11:54 am. The statement also notes that the incident “is associated with
rock fracturing within the volcanic edifice.” The volcano-tectonic
earthquake was presented to the southeast of the main dome at a depth of
12.33 miles. Although the movement was felt in the district Tapias,
rural Ibagué, Eduardo Rodríguez, director of the Departmental Committee
for Risk Management, confirmed that no emergencies have been reported
so far. The Cerro Machin volcano alert remains yellow. There have been
three earthquakes reported in the vicinity of the volcano within a
week. On Sunday two movements were recorded at 9:32 and 9:35 pm with a
magnitude of 4.6 and 3.9 on the Richter scale, respectively, located 12
kilometers southeast of depth to the main dome. The two municipalities
where the tremors were felt are Cajamarca and Ibague. Cerro Machin
last erupted 800 years ago. –Elnuevodia (translated)
El Hierro:
It seems a new earthquake swarm has started at El Hierro volcano
yesterday, when the number of quakes rose from an average of about 8-10
to 23 quakes per day. Today, so far there have been 14 events recorded,
and their number is likely to rise further. The quakes are very small
(mostly under M1, largest M2.0)
and are concentrated at about 10 km depth in the western El Golfo and
scattered in the SW part of the island at greater depths.
Iceland:
A new earthquake swarm occurred over the weekend on the Iceland’s
Reykjanes peninsula, on the volcanic rift zone about 12 km SW of
Brenisteinsfjöll volcano. The largest quake was a M3.8 event at 5 km depth on Friday at 19:42 UTC.
Yellowstone: A minor seismic swarm occurred at Yellowstone, but falls into what is normal activity at a large active caldera. -Volcano Discovery
