10 volcanic quakes rock Taal VolcanoBy PNA | Posted on Jan. 23, 2013
THE Philippine Institute of Volcanology and Seismology said Tuesday the seismic activity of Taal Volcano in Batangas province has increased in the past 24 hours.
Phivolcs Director Renato Solidum, Jr. said the agency has recorded 10 volcanic quakes from 7 a.m. Monday to 7 a.m. Tuesday.
But Solidum said no steaming has been observed in the past 24 hours and water temperature at the main crater lake decreased from 31.7 to 30.9 degrees Celsius.
The Phivolcs chief noted the volcano's Alert Level 1 will be maintained as "10 volcanic quakes are still appropriate for a volcano that is under abnormal level."
He said that a volcano under Alert Level 1 means that abnormal volcanic activities are observed, though a hazardous eruption is not imminent.
Since January 18, Solidum said Taal Volcano was relatively calm, with its seismic network recording "zero to eight" volcanic earthquakes in a day. PNA
Volcano activity of January 22, 2013 – Video hydrothermal activity at New Zealand White Island volcano (Good video)
Last update: January 23, 2013 by By Richard Wilson and Armand VervaeckThis (almost) daily post intends to follow up the activity changes of volcanoes all over the world.
This post is written by geologist Rodger Wilson who specializes in Volcano seismicity and Armand Vervaeck. Please feel free to tell us about new or changed activity if we haven't written about it. -
January 22, 2013 volcano activity
Following a visit to White Island volcano (New Zealand) over the weekend, GNS reports an increase in hydrothermal activity within the volcano's crater. Video of the activity shows strong roiling and "geysering" taking place within the crater lake. The White Island seismogram shows some local earthquake activity embedded with the "loud" volcanic tremor now occurring within the edifice. If the earthquake activity continues and/or increases, it could be the final warning the volcano gives before further (explosive) potentially dangerous activity.
Lava emission continues at three Kamchatkan volcanoes, Tolbachik, Kizimen, and Shevuluch today. Moderate (in the case of Kizimen and Sheveluch) to high (in the case of Tolbachik) seismicity accompanies the ongoing activity.
Local (and regional) seismicity remains elevated at Tanaga volcano (Aleutian arc) (station TAZE).
Numerous small earthquakes continue beneath Mammoth Mountain volcano (CA) (station MMS).
Volcanic earthquakes and small rockfalls continue at Colima volcano (Mexico) today. Emissions of gas and ash remain subdued at Popocatepetl volcano, occurring at an average rate of one event every one to two hours.
Seismicity is generally low at Guatemalan volcanoes Fuego (station FG3), Santa Maria (station STG6), and Pacaya (station PCG) again today. A period of volcanic tremor affected Santa Maria volcano (likely in conjunction with gas and ash emission) earlier this morning. Pacay volcano continues to "perk" with numerous, small, volcanic earthquakes.
Volcanic earthquakes are much reduced (in amplitude and number) at San Cristobal volcano (Nicaragua) (station CRIN), while variable volcanic tremor continues at Masaya volcano (station MASN). Periods of low-amplitude volcanic tremor are visible on seismograms from Concepcion volcano (station CONN) today.
Numerous small earthquakes continue to plague Colombian volcanoes Nevado Del Ruiz (station OLLZ), Machin (station CIMA), and Galeras (station ANGV).
Data from Ecuadoran volcanoes was not available today.
No updates in the past few days from SERNAGEOMIN pertaining to activity at Copahue volcano (Chile-Argentina border).
Eruptions of PNG Tavurvur volcano have forced some flights in and out of New Britain to be cancelled. The eruption ash affected flights to Tokua Airport. Newspaper reports say low to loud roaring and rumbling noises were heard on Sunday night when the volcano erupted.
Volcanic Activity at Kilauea's Summit
January 23, 2013
The current eruption of Kilauea Volcano is one of the longest in history. This false-color (near infrared, red, and green) satellite image (top) shows some of the ongoing activity. Halema'uma'u crater, near Kilauea's summit caldera, emits a thin plume of volcanic gases, including water vapor, sulfur dioxide, and carbon dioxide. Southeast of the caldera, active lava flows spread across Hawai'i's coastal plain. Invisible in the false-color image, the heat from the flows glows brightly in thermal infrared light (lower).
These images were collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer on the Terra satellite on January 7, 2013. Vegetation, which reflects infrared light strongly, is bright red in the thermal infrared image. Fresh lava flows (less than 50 years or so) are varying shades of black and gray. Clouds are white and ocean water is dark blue. The thermal infrared image shows temperature—cold areas are dark, while hot areas are bright.
