25 earthquakes recorded at Philippines’s Taal volcano in 24 hours

Posted on May 7, 2011 by The Extinction Protocol
May 7, 2011 – MANILA – After being relatively quiet in past days, restive Taal Volcano in Batangas province showed intensified activity anew, with state volcanologists recording 25 volcanic quakes there in the last 24 hours. In its Saturday update, the Philippine Institute of Volcanology and Seismology (Phivolcs) also noted an increase in water temperature and acidity at the Main Crater Lake. “Taal Volcano’s seismic network recorded 25 volcanic earthquakes during the past 24 hours. Field measurements conducted on 05 May 2011 at the eastern sector inside the Main Crater Lake showed that the water temperature increased from 31.5 to 32.0 degrees Celsius, the water became more acidic with pH value decreasing from 3.09 to 2.94 and the water level further receded to 0.19 meters from the 0.23 meters as compared to the last reading on 19 April 2011,” it said. Carbon dioxide emission as of May 3 and 4 was at 2,057 tons per day (t/d), slightly down from 4,750 t/d last March but higher than the 1,875 t/d last February. Phivolcs said Alert Level 2 remains over Taal Volcano with the interpretation that magma has been intruding towards the surface. It reminded the public the Main Crater, Daang Kastila Trail and Mt. Tabaro are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate. “Breathing air with high concentration of toxic gases can be lethal to (humans and) animals and even cause damage to vegetation,” it said. Also, it reminded the public the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended.”  –GMA News

    Alvin:

    Thank you for this valuable resource; your blog is among my RSS feeds, I read nearly every post, and your book is on my wish list.

    I don’t recall whether here or somewhere else, but recently I read a post that indicated that a small series of quakes in the 5.0 range can be a precursor to a more catastrophic quake in the same area.

    But otherwise, my understanding has been that smaller quakes release pressure, making more damaging quakes less likely; yet most quake reporting seems to imply that increasing numbers of quakes foreshadow more tragic events.

    If you’re so inclined, I’d value your comments regarding this; in particular, does recent quake activity both north and south of the USA west coast make a catastrophic quake more or less likely. (This particular post, as it pertains to volcanic-related quakes, is probably not as relevant to my question as non-volcanic quakes.)

      Good question John and since you mentioned the book. I’ll list a quote from it since I used one such study as a precusor to forecast more quake activity: “Since January 14, 2010, and two days after the Haiti earthquake, the Earth began experiencing a notable uptick in 5.0 magnitude earthquakes. Over a six-day period, beginning on the 14th of January, for example, there was as average of 6.8 magnitude 5 earthquakes per day, when before the earthquake in Haiti, the normal average was closer to 2.9 per day.” page 149, The Extinction Protocol

      What followed was the 7.0 earthquake in Ryuku Islands in Japan on February 27, 2010 and the 8.8 quake in Chile on February 28, 2010. In reality, only large quakes really alleviate stresses and 5.0 moderate quakes are generally a sign pressure is building. Regarding the West Coast, that depends on the quake events. Haiti’s January 7.0 was followed by April’s 7.2 earthquake in Baja California. I think the Caribbean tension will destabilize surrounding plates, Cocos, Nazca and potentially the Pacific (California) – so I would say, the more catastrophic of a quake occurs, the more likely energy transference will perturb another adjacent region.
