Taal Volcano’s main crater has again spewed steam-rich plumes on Wednesday (August 11) after a pause of 16 days, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

“Activity at the main crater was dominated by upwelling of hot volcanic fluids in its lake which generated plumes 3,000 meters tall that drifted to the general north,” according to the latest bulletin of Phivolcs.

As of August 9, the amount of sulfur dioxide (SO2) emitted from the main crater reached 3,849 tonnes/day. There were also 107 volcanic earthquakes recorded over the past 24-hour observation period, including 100 volcanic tremor events which lasted from two to 30 minutes, six low-frequency volcanic earthquakes, and one hybrid event.

Alert Level 2 remains over Taal Volcano. Phivolcs stressed that entry into Taal Volcano Island and Taal’s permanent danger zone is strictly prohibited. AAC

PNP vows justice for rape-slay victim in Batangas

Robie de Guzman   •   November 11, 2021

Outgoing Philippine National Police (PNP) chief Police General Guillermo Eleazar has directed the local police in Laurel town in Batangas to build an airtight case against the alleged perpetrators in the rape and slay of a 15-year-old.

Initial report stated that the victim had just come over to her classmate’s house so they could answer their module together on Monday morning but had not returned home by nightfall, causing her family to worry and search for her.

Her body was later found in a forested area in Barangay Sta. Maria.

Police said there were indications that she was sexually abused.

A witness told the local police that the teenager was last seen in the company of a barangay tanod. The barangay tanod was arrested and taken into police custody on Tuesday, November 9 but has denied any involvement in the crime.

Eleazar expressed his condolences to the victim’s family as he vowed that the PNP will give justice to her death.

“Bilang magulang ramdam ko ang sakit at pagdadalamhati ng mga naulila ng biktima. Ako ay nakikiramay sa pamilya ng dalagita na malayo pa sana ang mararating sa buhay. Titiyakin ng PNP na airtight ang kaso para siguradong mapanagot sa batas ang salarin sa karumal-dumal na krimen na ito,” PGen Eleazar said.

“Sa ngayon, hawak natin ang isang barangay tanod na sinasabing nasa likod ng krimen. I have ordered the Laurel Municipal Police Station in Batangas to leave no stone unturned in gathering evidence to the crime to make sure they get the real perpetrator or perpetrators,” he added.

Eleazar appealed to those who may have information on the incident to come forward and help authorities give justice to the teenager.

 

Phivolcs records sequence of earthquakes in Bicol region

Maris Federez   •   October 18, 2021

MANILA, Philippines — The Department of Science and Technology-Philippine Institute of Volcanology and Seismology (DOST-Phivolcs) has recorded a sequence of small earthquakes in the Bicol region following a small shallow-seated earthquake with a magnitude of 4.3 and depth of 4 kilometers occurred at 10:08 p.m. on October 14.

The location of the epicenter of the 4.3 magnitude quake was determined to be at 13.65 north latitude and 123.14 east longitude or at 3 kilometers North and 75 kilometers west of Canaman, Camarines Sur.

A total of 27 earthquakes were recorded by the nearest DOST-Phivolcs earthquake monitoring station located in San Jose, Camarines Sur (Station Code: SCSP).

Magnitude ranges from 1.7 to 4.3 with crustal shallow depths between 1 to 40 kilometers.

The last recorded event associated with this earthquake sequence was at 1:22 a.m. on Monday, October 18.

There was no similar event that followed as of 6:00 a.m.

Phivolcs also recorded ten events that were felt at various intensities in the provinces of Camarines Norte, Camarines Sur and Albay.

Calculation of the intensity distribution for the first event was performed using the Rapid Earthquake Damage Assessment System (Redas) software using the latest calculated parameters of the earthquake, according to the statement released by the DOST.

Results show that the magnitude and shallow depth of this inland event has the potential to cause damage in the general vicinity of the epicenter.

The department said it immediately informed the Office of Civil Defense (OCD) about this during the information release of the first event.

The DOST also noted that social media posts indicate that the event was widely felt with unconfirmed observations of non-structural damage (glass door was damaged) and damage to building content.

This prompted OCD to instruct their regional office to investigate the reported damage in the affected areas.

DOST-Phivolcs said that based on the collected data, this sequence of events, showing no identifiable large event, can be considered as an earthquake swarm that may occur in a tectonically active region, as suggested by sparse seismicity in this area of the Bicol region.

DOST-Phivolcs said it will closely monitor any progress of this earthquake activity and will continue to post updated information at the Phivolcs Official website.
