Nicaragua
gregladen | September 8, 2014Remember that asteroid that was supposed to pass harmlessly by the Earth on Sunday? Well, things didn't go exactly as planned...
Apparently, a meteor hit Nicaragua late Saturday night, forming a 12 meter wide crater. This would be a small chunk to make a crater that little. It has not been confirmed yet, but there is a strong possibility that this meteor was associated with 2014 RC. NPR quotes AP which quotes a Nicaraguan government official as saying the meteor "appears to have come off an asteroid that was passing close to Earth." NPR also quotes the BBC which quotes another astronomer…

A Dangerous Paradise
From jungles with jaguars to crystal blue lakes with freshwater sharks, Nicaragua is one of the most beautiful and dangerous countries in Central America. The brilliant biodiversity attracts millions of tourists each year and the looming volcanoes that pepper the landscape can be an exciting yet unsettling sight. However, in reality much of the danger in Nicaragua comes from the risk of infectious diseases. For example, if you’re planning to travel to this tropical paradise anytime soon, the Center for Disease Control (CDC) states that…

Concepcion seem from the ISS in 2007. Image courtesy of the NASA Earth Observatory.
One brief bit of news:Concepcion in Nicaragua erupted, covering three nearby villages with ash. The brief report only mentions 150 meter / 400 foot explosion columns from the eruption, which makes me thing this is merely for the ballastic clasts. No other details - on the eruption or any evacuations - are available.
Concepcion is in the middle of Lake Nicaragua on the island of Ometepe (and the original Mystery Volcano Photo). The volcano last erupted in 2007…
eklemetti | September 9, 2009The first Mystery Volcano Photo (MVP, for short) seem to go well and indeed, the volcano in question was Concepcion in Nicaragua. Congratulations to volcanista for nailing it on the first try. I'll have to keep a tally of the winners for each MVP to name a, well, MVP MVP. So far, the scoresheet looks like that.
Volcanista - 1
All the rest of yous - 0
I think we know who has the upper hand.
Volcan Concepcion on Isla Omtepe in Nicaragua.
Anyway, Concepcion! The volcano is a stratovolcano on the island of Ometepe in Lake Nicaragua, which it shares with Madera, another active stratocone. It is…
eklemetti | September 6, 2009San Cristobal in Nicaragua
I don't have much in the way of details, but the Associated Press is reporting that San Cristobal in Nicaragua has erupted this evening. The volcano reportedly experienced an explosive eruption and that nearby villages (how nearby is unclear) have received ash fall from the eruption. If it is any indication, government officials did issue a warning to 25 districts around the volcano and so far no casualties have been reported.
UPDATE 8:30 AM (EDT) 9/7/2009: A few more details have come out about the eruption. The ash plume reached ~8,000 m / 26,000 feet, although…
eklemetti | May 8, 2009Things are busy - both volcanically and personally - so I'm going to just give you some links to a bunch of exciting/interesting/insane news:
West Mata erupting on May 5, 2009 in the Lau Basin.
According to a bunch of news sources, the eruption at Fernandina in the Galapagos is over (in spanish). That being said, the PNG noted that there is still a lot of carbon dioxide and sulfur dioxide being emitted, suggesting there is still a lot of degassing magma beneath the vents - at what depth (and will it erupt) is the question.
There is a lot of speculation that Nyiragongo (DRC) is erupting or…

Eruptions and earthquakes go hand-in-hand a lot of the time. It only makes sense as magma needs to move under the crust, causing movement (i.e., earthquakes). Additionally, any sort of explosions caused by the release of volatiles might cause earthquakes or even the collapse of an edifice (which in turn, shakes the earth).
So, it is not surprising that the current eruption at San Cristobal in Nicaragua has produced earthquakes. The reports are relatively lacking in details, but San Cristobal is a typical Central America stratovolcano that produces frequent Strombolian style eruptions, which…

Some news of a series of small eruptions at San Cristobal in Nicaragua. Ash from the small explosions drifted to a town near the volcano, however officials for Ineter in Nicaragua say that there is little chance of a large eruption.
San Cristobal is one of the seven active volcanoes in Nicaragua. It has a long record of small eruptions, with at least one every year in the 21st century (and beyond). The largest eruption in recent times was in 1999 that produced lahars and an explosive eruptions (landing us at VEI 2).
