There have been reports of fumaroles on the western side of the crater. These have not been verified visually yet because it s dark out. - An overnight thermal imaging flight report just came in. The crater floor is without question significantly hotter than the rest of the volcano, but they could not get precise temperatures owing to interferences from clouds. - Almost 70 distinct seismic events in the past hour. The ratio of LPs to VTs is back to what it was a day ago (more LPs than VT quakes) and the focus of most quakes is shallower than 2 km depth.. - 42 distinct seismic events in the past hour, mostly LP.

PFs have overcome all regions within 10-15 km of the summit. - Lahars are beginning to flow at devastating speeds and with enormous volumes down the W and SW flanks of the volcano; L-SRAM is still operational and indicates significant activity there now. -Ash and pumice are still falling throughout the area; traffic has come to a complete halt in Quito, the airport is closed, and nobody is on the streets. As Coto continues to belch out a modest amount of material, activity appears to be waning somewhat as visibility increases in the city, at least. Nevertheless, at this point any real observations are impossible. What is left of southern Quito has a 8-10 cm layer of ash and pumice on top of it, but the ash is still falling. No reports yet from towns to the SW of the volcano.

No reports yet from towns to the SW of the volcano. - There are no working seismometerss left, but the rumbling has subsided and Coto is no longer ejecting material. The mountain, the entire countryside, and most of the city are steaming and mantled in ash, pumice, and debris. There s no color to the landscape except where fires are burning in destroyed buildings where gas tanks have ignited them.

The mountain, the entire countryside, and most of the city are steaming and mantled in ash, pumice, and debris. There s no color to the landscape except where fires are burning in destroyed buildings where gas tanks have ignited them. Quito is ravaged, but some semblance of a rescue effort is beginning to come together from the survivors.

Quito is ravaged, but some semblance of a rescue effort is beginning to come together from the survivors. -As a more complete picture of what happens comes in, it seems as though after Coto started its climactic eruption, the lava began interacting with melted glacial ice that had accumulated in the crater. This instantly increased the magnitude of the eruption immensely. As the clouds begin to settle, it is obvious Coto blew out the entire upper half of its peak, which soon came back down and created a base surge. The surge overwhelmed all of the topographic features and overtook almost all of southern Quito as well as many inhabited areas to the W and SW of the volcano. Major lahars remobilizing the abundant ash and pumice continue to decimate areas to the SW and W of the volcano for up to 25 km.

The mountain is still. - Contact with the mayor s office has been established. They are understandably busy, but would like an update ASAP.

He has not been seen since… El Niño

144 Day 7 6:15 PM VDAP RESPONSE TEAM Cotopaxi ACTIVITY Working seismic Stations: 0 Seismic events over past hour: N/A Eruptions in last 24 hours: 12 Days until budget runs out: 0 But wait! Proving that you can never keep a good dog down, El Nino was found! Fortunately, the part of Machachi where she liked to hang out was protected from the surge by Ruminahui volcano. The children rejoiced and a sense of hope was returned to what is left of Quito. However, she was given a stern talking to and was told never to wander that far from home ever again…

PREPARE A PREDICTION OF FUTURE ACTIVITY AND POTENTIAL HAZARDS FOR EVERYONE YOU ARE LEAVING BEHIND. - TIME TO LEAVE QUITO. BEFORE YOU LEAVE MAKE SURE YOU SAY GOODBYE TO ALL YOUR NEWFOUND FRIENDS AND GIVE YOUR REPORT TO THE MAYOR. Report to headquarters as soon as your report is finished. And remember…in the battle between man and the volcano…

146 NATURE ALWAYS WINS.
