and a village in the Philipiennes,,lava flow as well??
LEGAZPI CITY, Philippines—Volcanic activities have slowed down on Mt. Mayon but the possibility of a hazardous eruption remained, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
Despite earlier fears that Tropical Storm “Mario” would loosen lahar flow from the volcano, an official from the Albay Public Safety and Emergency Management Office (Apsemo) said no such flow occurred in Barangay Maipon in Guinobatan, Albay province.
Eduardo Laguerta, Phivolcs resident volcanologist at the Lignon Hill observatory here, said seismic networks on Friday showed there were 22 volcanic quakes and 70 rockfalls, much less than Thursday’s 142 volcanic quakes and 251 rockfalls.
The volcanologist said the number of volcanic quakes and rockfalls was an indicator of magma movement and the slow extrusion of magma on Friday indicated “a lessening of Mayon’s activity.” Despite that, the possibility of an imminent eruption remained, he added.
“In the history of Mayon, once the lava dome has been noted at the surface, [the volcano] will erupt,’ Laguerta said.
An updated report from the National Disaster Risk Reduction and Management Council (NDRRMC) showed that at least 6,766 families, or 27,755 people, had been evacuated to 27 evacuation centers as of Friday, as volcanic earthquakes and rockfalls from Mayon continued over the last 24 hours.
Permanent danger zone
The evacuated families came from Camalig, Guinobatan, Daraga and Malilipot towns, and Ligao and Tabaco cities, all within the 6-kilometer permanent danger zone (PDZ), according to NDRRMC Executive Director Alexander Pama.
The update also quoted the Department of Social Welfare and Development (DSWD) as saying it had provided evacuees with P6,670,508.93 worth of family food packs, assorted food items and nonfood items, and pre-identified 2,142 evacuation centers in Camarines Sur, Camarines Norte, Albay, Catanduanes, Sorsogon and Masbate provinces.
Phivolcs raised alert Level 3 over Mayon on Monday and warned of a dangerous eruption within weeks after it noted magma rising to the top of the volcano and “rolling incandescent rockfall” on its slopes.

Guys, if you're still around, what are these long signatures on STAR at Rainier? In particular, the event at 19:56 UTC.
The frequency on the PNSN spectros looks fairly low.
PNSN spectro for Rainier stations
The ice skidding? They almost look like the elusive "tornillos" on the seismograms.
Same station, but stretched out
Also show on Camp Schurman. Muir station just looks screwy.
that scenerio is only based on 20/09/2014, I'll check back and see if it stacks up prior, the daily depth graphs need to be compressed in latitude to be able to see. I'll start back at the 16th Aug.
Wet day here I have the time.
