Pyroclastic Flows At Santiaguito Volcano In Guatemala

Activity has picked up during the past days: a series of partial collapses from the Caliente lava dome has been generating small to moderately large (up to 4-5 km long) pyroclastic flows, the volcano observatory reported in its latest special bulletin.

Seismic activity prompts alert at Alaska Peninsula volcano

Volcano Alert

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.”
 
“Over the past day, seismicity at Veniaminof has increased and is ongoing in the form of volcanic tremor,” staff at the observatory wrote. “No eruptive activity is observed in web camera or satellite views from today.”
 
Veniaminof has seen numerous eruptions over the last century, including one that produced a 20,000-foot ash plume and ash falls over a 25-mile radius in 1939. Since the turn of the century, it has had at least six eruptions, including one in 2013 that generated lava and ash plumes.
 
John Power, the observatory’s scientist in charge, said the recent activity seems to be “something new,” with no significant activity preceding it in recent weeks. 
 
“This seems to be what we have seen at Veniaminof numerous times in the past,” Power said. “It’s a very frequently active system, and this seems to be in keeping with prior eruptions.”
 
While scientists don’t have any predictions on whether the latest seismic event at Veniaminof will lead to a new eruption, Power said the volcano will remain under observation.
 
“We are watching the situation very closely,” Power said.

Supermoon tides flood South Florida residential areas for 3rd day

Flood Alert

South Florida residents continue to brave tidal flooding from Sunday’s supermoon.
 
Locals in Miami Beach caught a small break, Thursday morning, before the tide rises again, causing water to flood ankle-deep.  
 
Tourists have been caught of guard dealing with the standing water. “I’m not used to it,” said one tourist from Israel.
 
Residents as far as North Fort Lauderdale continue to feel the effects as well. “You’re going to need a kayak or canoe,” said a resident. This seasonal high tide usually occurs at the end of October and at the end of November, but residents say they have never seen the water quite this high.
 
Pumps will continue to work overtime to relieve the flooding, which is expected to last until Friday. Officials have made sure that drains in these areas are clear of debris and are hopeful that the water levels will go down very soon.
 
The next high tide is expected at 11 a.m. Thursday.
