Mexico's Popocatepetl Volcano registered a mild eruption on Sunday,
sending a plume of smoke and steam two km high, authorities
said.
The eruption registered at 9:04 a.m.local time (1404 GMT) was the fourth in 24 hours, according to the National Disaster Prevention Center (Cenapred) of Mexico.
The eruption registered at 9:04 a.m.local time (1404 GMT) was the fourth in 24 hours, according to the National Disaster Prevention Center (Cenapred) of Mexico.
"In the past 24 hours, the Popocatepetl Volcano monitoring system registered 88 low-intensity exhalations and four explosions, including two on Saturday at 12:52 p.m. (1752 GMT) and 8:50 p.m. (0150 GMT Sunday), one on Sunday at 6:22 a.m.
(1122 GMT) and this latest one," said
Cenapred. The agency also detected "a light emission of gas and
steam to the northeast" of the volcano, located some 70 km
southeast of the capital Mexico City, home to more than 20 million
people.
The Popocatepetl Volcano has been mildly active since
Dec. 21, 1994, and a "yellow phase 2" caution alert has
been in place ever since, meaning people must keep outside a 12-km
radius around the crater.
After a powerful 7.1-magnitude quake struck central Mexico on Sept. 19, the volcano registered two eruptions of steam and gas in the following four days.
However, officials say they have not observed any significant uptick in volcanic activity in relation to the quake.
Today's eruption is the 9th to occur in just over a week around the ring of fire, the impressive list of volcanoes showing activity this month is as follows: Indonesia: Lewotolo Volcano, Mount Agung and Mount Sinabung, Mexico: Colima and Popocatepetl Volcano, Costa Rica: Turrialba Volcano, Guatemala: Fuego Volcano and last but not least, Vanuatu: Manaro Voui Volcano, Japan: Shinmoedake.
Volcano eruption triggers threat level increase in southwestern Japan
Japan's
Meteorological Agency has raised the alert level for the Kyushu
region to three on a five-grade scale, after a volcano on Mount
Shinmoe in the Kirishima mountain range erupted for the first time in
six years early Wednesday morning.
No
injuries or damage have been reported so
far, according to local police, after ash fell on the town of
Takaharu following the 5:34am eruption at Shinmoe which sent plumes
of smoke some 300 meters into the air.
The
volcano, which continues to show signs of increased activity,
prompted Japan's Meteorological Agency to raise the alert level to
three, advising people to stay away from the active crater. The
highest level 5 would require people to evacuate the area.
The
eruption continued after the initial blast, with the amount of plume
steadily increasing. In addition, volcanic tremors are also
continuing with the amplitude gradually increasing, the agency said.
It warned people to watch out for “large
burning stones and pyroclastic flow” within
a two-kilometer range from the crater.
The
last major eruption of the volcano took place on September 7, 2011.
Volcano
warning: Canary Islands panic as earthquakes hit La Palma – 40
tremors in 48 hours
FEARS
of a volcano erupting on the Canary Islands has sparked panic as the
Spanish archipelago was hit by more than 40 earthquake tremors in
just 48 hours.
10
October, 2017
La
Palma was rocked by more than 40 seismic movements of low magnitude
and intensity between 1.5 and 2.7 on the Richter scale, according to
the data of the National Geographic Institute.
The
biggest earthquake, recorded at around 1pm on Saturday, had a
magnitude of 2.7 and took place in the area of the Natural Park
Cumbre Vieja, 28 kilometres deep.
The
second largest quake, of 2.6, took place at 1.23pm on Sunday in the
same area, while the third quake erupted at midnight on Monday,
reaching a magnitude of 2.1, according to the Volcanological
Institute of the Canary Islands (Involcan).
The
earthquakes have sparked panic across the Canary Islands, with
volcano experts pulled in to examine the unusual seismic activity.
María
José Blanco, director of the National Geographic Institute in the
Canary Islands, said the island has "never recorded a similar
swarm" and although the energy levels are low and very deep, it
is different from the seismic activity they have recorded so far.
The
Ministry of Territorial Policy, Sustainability and Security of the
Government of the Canary Islands, respecting the Special Plan for
Civil Protection and Emergency Care for Volcanic Hazards, will meet
with the Scientific Committee of Evaluation and Monitoring of
Volcanic Phenomena, to evaluate the data obtained from monitoring
stations on the island.
A
scientific team of five will also visit La Palma to keep track of the
tremors in situ.
Ms
Blanco said the team will start to increase the number of seismic
stations in the volcanic monitoring network in a bid to develop the
geochemical measurements usually carried out in the island of La
Palma.

The
last significant seismic activity in the archipelago took place in
2011 on the island of El Hierro, which finally led to the eruption of
an underwater volcano in the southeast of the island.
The
eruption was followed by more than 7,500 earthquakes, which lasted
for three months.
La
Palma is a volcanic ocean island, which rises almost 7km above the
floor of the Atlantic Ocean. There is road access from sea level to
the summit at 2,426metres, which is marked by rocks called Los
Muchachos.
It
was originally formed as a seamount through submarine volcanic
activity and is currently, along with Tenerife, the most volcanically
active of the Canary Islands.
The
island is composed of two large volcanic centres.
The
northern part of La Palma is dominated by the older Taburiente, with
a width of 9 km and a depth of 1,500 metres and is surrounded by a
ring of mountains ranging from 1,600m to 2,400m in height.
Around
a half a million years ago, the Taburiente volcano collapsed with a
giant landslide, forming the Caldera de Taburiente.
But
the younger 1949-metre-high Cumbre Vieja, the southern volcano, is
one of the most active in the Canaries.
