An Alaska Peninsula volcano that has long been a hotbed of seismic activity prompted a new alert from volcanologists Thursday, though no signs of an eruption have been seen so far.

According to a statement from the U.S. Geological Survey's Alaska Volcano Observatory, the alert level at Mount Veniaminof -- a volcanic peak about 480 miles southwest of Anchorage and 22 miles north of Perryville -- has been raised to "advisory," and the aviation color code has gone from green to yellow.

According to a USGS guide on volcano alert levels, Veniaminof's current aviation color code and alert level both indicate that it is "exhibiting signs of elevated unrest above known background level."

Colima Volcano in Mexico erupts again

The Colima volcano in Mexico has erupted, spewing ash and smoke two thousand metres into the air.
Footage has emerged of the Colima Volcano in Mexico erupting.

Three consecutive explosions were caught on camera, as smoke and ash were spewed 2,000 metres into the sky.

This is the latest of several eruptions this year for the Colima Volcano, the most recent occurring in July.

Since then the active volcano has continued to show signs of imminent activity.

Situated on the west coast of Mexico, straddling the states of Colima and Jalisco, the volcano is the one of the most active in Mexico and North America.

Spectacular footage of the Ubinas Volcano in south-west Peru erupting on Monday, sending clouds of ash up 4,000 metres into the air. Marco Rivera, a coordinator for local volcano-observation group Ingement, says a body of heat was also observed inside the crater of the active volcano. Authorities have issued an ash alert for towns and communities surrounding the volcano.

Chilean volcano sends massive plume of ash into the sky just months after first in eruption in 40 years

Up in smoke: This is the incredible moment that Volcano Calbuco blew its top sending a huge cloud of ash into the sky
This is the incredible moment a Chilean volcano sent a huge plume of ash into the sky.

Volcano Calbuco, in the country's south, had laid dormant for more than 40 years when it suddenly erupted in April, causing thousands to flee.

Just five months later, Calbuco, considered to be among the three most dangerous of Chile's 90 active volcanoes, was captured spewing lava again.

Firefighter and amateur photographer Eduardo Minte, 28, from Osorno, Chile, took the pictures at Llanquihue Lake between the towns of Frutillar and Llanquihue earlier this month.

'This eruption was one of the most incredible things I've ever seen. My jaw dropped - it was like the almighty was descending from the heavens,' he said.

More activity seen at Colima Volcano, Mexico

Colima Volcano
The Colima Volcano continues to be active, sending a 1,500-meter column of smoke skyward at 7:08 this morning.

Civil Protection's national coordinator, Luis Felipe Puente Espinosa, reported the eruption on his Twitter account, advising that the smoke, with a low ash content, was moving southwest.

The ash expelled by the volcano consists of material less than two millimeters in diameter and moves with the wind. But rock projectiles from the Volcano of Fire, as it is also known, are a different matter.

They can be up to 50 millimeters in diameter and are sent shooting out of the crater at high speed, before falling to the ground. This volcanic material can cause damage and injuries in populated areas, particularly if they are hot, which can result in fires.

The Telica volcano located in northwestern Nicaragua has once again erupted, after it started spewing smoke on Wednesday.

According to the AFP, civil defense officials in the region have described dense volcanic ash settling over the six surrounding villages. Evertz Delgadillo, a member of the local municipal disaster prevention committee, said the first explosion lasted 20 minutes and was followed by three other shorter explosions.

Back in May, the 90-mile-high volcano erupted twice.

The Nicaraguan government has previously shown some hesitancy in ordering the evacuation of the people who live near the active volcano.

A new eruption has been reported yesterday from the volcano, which has last been active 105 years ago.

An ash plume was seen rising approx. 1 km and drifting NW from what looks like a lateral vent on the northern slope of the volcano near Arusha town. The are no reports of damage or fatalities.

According to local sources, people in the area around the volcano have been experiencing an increased number of small felt earthquakes in recent months.

Mexico towns blanketed with ash Colima volcano erupts

Mexico's Colima volcano has spewed ash and smoke over nearby towns, after erupting again at dawn yesterday.

Video from the scene showed thick plumes of black smoke billowing from the mountain.

"The ashes and smoke have reached two kilometres into the air... it has been showing renewed activity over the past two months, blanketing nearby villages with ash," teleSUR English reports.

Colima, also known as Fire Volcano, is located in the country's west, about 125km from Guadalajara in Jalisco.

It is the country's most active volcano and has erupted more frequently since 1994, according to Volcano Discovery.

Hundreds of people were evacuated from nearby towns in July amid fears of a major eruption.

Airline Aeromexico has not advised of any delays.

Volcano alert level for Mauna Loa, Hawaii elevated

The amount of small earthquakes beneath the summit of Mauna Loa has more than tripled recently prompting the U.S. Geological Survey to increase the volcano alert level from "normal" to "advisory". On the color scale, it went from green to yellow.

"Over the past year we've been locating, on average, around 150 earthquakes per month," says Weston Thelen with the U.S.G.S. who says normally, fewer than 40 earthquakes a month are reported.

The last time Mauna Loa erupted, was in 1984. The lava flowed for 22 days. More than 30 years later, the mountain is stirring again.

"Really, we're seeing a persistence in this unrest," says Thelen, "We're not saying that an eruption is imminent, we're not even really certain that there is going to be an eruption." But the shallow earthquakes are occurring in the same areas that preceded the mountain's most recent eruptions.

Volcanic eruptions and earthquakes increasing across the planet

If it seems like earthquakes and erupting volcanoes are happening more frequently, that's because they are. Looking at global magnitude six (M6) or greater from 1980 to 1989 there was an average of 108.5 earthquakes per year, from 2000 to 2009 the planet averaged 160.9 earthquakes per year: that is a 38.9% increase of M6+ earthquakes in recent years. Unrest also seems to be growing among the world's super-volcanoes. Iceland (which is home to some of the most dangerous volcanoes on the planet), Santorini in Greece, Uturuncu in Bolivia, the Yellowstone and Long Valley calderas in the U.S., Laguna del Maule in Chile, Italy's Campi Flegrei - almost all of the world's active super-volcanic systems are now exhibiting some signs of inflation, an early indication that pressure is building in these volcanic systems.

When they will erupt is guess work, but in the meantime, activity is growing in Central America's volcanoes such as Costa Rica's Turrialba Volcano, Asia's volcanoes such as Kamchatka, Alaska and Indonesia are also more active. Magma chambers are growing as pressures increase, the numbers of tremors are increasing as are related 'quake-clusters'. If any one of these major volcanic systems has a large scale eruption, it would be a global event. Iceland is considered by many scientists to be the next likely place for a global level volcanic event. The last major event, actually relatively minor, was in 2010 when an Icelandic volcano (Eyjafjallajökull volcano) made headlines around the world by spewing mega-tons of ash into the atmosphere, cancelling and re-routing thousands of flights and costing airlines and passengers more than $7 billion+ in lost revenues.
