Info from IMO tonight:

Glacial water is flowing into Múlakvísl river, south of Mýrdalsjökull. Increased conductivity has been measured in the river and gas measurements in the area show high concentrations of sulfur dioxide and hydrogen sulfide. People are advised not to travel near the river, due to gas pollution. It is not uncommon for glacial water to flow into Múlakvísl, causing increased conductivity and gas pollution.

According to local reports, the level of the Bláfjallakvísl glacial river is unusually high. Bláfjallakvísl originates from the northern side of Mýrdalsjökull and people are advised to show caution when crossing the river.

BREAKING CIVIL PROTECTION UNCERTAINTY PHASE DECLARED

The National Commissioner of Police and the District Commissioner of Police in South Iceland have declared a Civil Protection Uncertainty phase due to seismic unrest in Katla volcano in Mýrdalsjökull. The contingency plan for an eruption in Mýrdalsjökull has been activated accordingly. Uncertainty phase means that a course of events has started that may lead to natural hazard in the near future. Monitoring, assessment, research and evaluation of the situation is increased.
Increased seismic activity started on September 29 and is still ongoing. Following a meeting with the Scientific Advisory Board of the Icelandic Civil Protection it is likely that the seismic activity is caused by magma movement within the Katla caldera. Three most likely scenarios have been defined.
1 Seismic activity dies out with no further consequences
2. Glacial outburst flood, jökulhlaup, will emerge from the glacier due to a small eruption or emptying of cauldrons
3. Eruption starts in Katla Myrdalsjökull that will force its way through the 400 meter thick ice with glacial outburst floods and ash fall
Accordingly a warning has been issued for travelers in the vicinity of Mýrdalsjökull Especially around glacial rivers.

México: centenas de pessoas foram deslocadas devido à lava de vulcão em Colima

As autoridades mexicanas instalaram um perímetro de segurança de 12 quilómetros em redor do vulcão ativo localizado no estado de Colima, o que implicou a retirada de 400 pessoas, divulgou a proteção civil local.


As medidas de precaução obrigaram à retirada da população de localidades como Becerrera e La Yerbabuena, indicou o governador, José Ignácio Peralta.

Outras localidades situadas no estado vizinho de Jalisco foram também evacuadas por precaução, informou a proteção civil.

Segundo as últimas informações, a lava do chamado "Vulcão do Fogo" já transbordou da cratera, situada a 3.900 metros de altitude, percorrendo mais de um quilómetro.

Earthquake, the director of the Vesuvius Observatory: "Alert in Campi Flegrei"

Interviewed about the repercussions of the earthquake in the Neapolitan Apennines, Francesca Bianco emphasized what is the one "yellow alert" at the time

"
... "The real problem, explains Francesca Bianco, are the Campi Flegrei:" The only area to be monitored seriously, indeed that we monitor very carefully. Here the alert is yellow, there is a very slow lifting of some tens of centimeters It has been going on since 2005 and we also have an important variation in the chemical composition of the fumaroles of Solfatara and Pisciarelli "
