Volcanic Tsunami possible after eruption in the Philippines

Perhaps we should suggest to the greens that the only way to save the planet from global warming is to set off a few volcanoes, presumably by dropping nukes in the middle of them.
Strangely enough that is the main part of the founding myth of Scientology.

Xenu brought people to earth in WWII bombers, stood them on volcanoes and nuked the lot of them. The resulting trauma is why we are all so fucked up mentally.

You can’t make this shit up. Oh, Hubbard did make it up you say!
 
That little island in Taal lake is called Vulcan Point and is apparently one of only two* third order islands in the world (and the largest). Also apparently called a sub-sub-sub island.

I can’t find any evidence of a fourth order lake.

Sadly I think the other third order lake might soon be both the biggest and the only example when the volcano pops it’s clogs.

*The evidence for two or three is a bit confusing.

I am in Manila at the moment, and meant to be getting married at tagatay at the end of the month. The ash fall in Manila stopped on Monday as the winds moved to the east. Even though the government and schools are still closed most businesses are still open. The biggest problem has been the bulk buying and increased cost of the N95 face mask which normally will cost php 30 are now around php 200. Hopefully the current events will subside without a explosive eruption, however, Taal volcano has form for erupting for 200 days.

So far since 12/01 there has been 520 earthquakes in the area, the crater lake has disappeared. As well as new vents being formed. The pansipit river has also dried up in places. They are still expecting Taal to violently explode soon. Luckily the wind has changed to the SW sending the ash cloud away from the metro Manila area.

The lake that surrounded the volcano has dried up, either by boiling off, or as a result of a 4.5 meter rise in the level of the Volcano itself! Pansipit river flows from the larger lake to the Philippine sea and it has reported that volcanic vents have appeared in the river bed.
 
Just had a look at the latest status. Simmering nicely.


The time lapse film of the lightning is pretty impressive (less impressive is the BBC calling it lightening).
Anyone who engages in lightening is simply a self-loathing racist.
 

A tsunami is a huge sea wave, or also known as a seismic sea-wave. They are very tall and height and have extreme power. A tsunami is formed when there is ground uplift and quickly following a drop. From this, the water column is pushed up above the average sea level.

Volcanic tsunamis can result from violent submarine explosions. They can also be caused by caldera collapses, tectonic movement from volcanic activity, flank failure into a water source or pyroclastic flow discharge into the sea. As the wave is formed, it moves in a vertical direction and gains great speeds in deeper waters and can reach speeds as fast as 650 mph. In shallow water it can still be as fast as 200mph. They travel over the continental shelf and crash into the land. This power doesn’t decrease when they hit land though, there is an extreme amount of energy when the water travels back towards its source.

Approximately 5 percent of tsunamis are formed from volcanoes and approximately 16.9 percent of volcanic fatalities occur from tsunamis.

Just for clarity I assume you mean the crater lake inside the volcano?

I can’t find a news update younger than nine hours and that says the PHIVOLC people say it may go into a lull.

Yes the lake that surrounded the erupting volcano, not Lake Taal which surrounds the island. However the Pansipit river flows from Lake Taal southwest to the Philippine Sea, and parts of that river system have dried up, and fissures and vents have formed in the river bed.

Philvolcs bulletin issued 15th Jan at 17:00:

"In addition to the previously identified fissures in Lemery (Sinisian, Mahabang Dahilig, Dayapan, Palanas, Sangalang, Poblacion, Mataas na Bayan), Agoncillo (Pansipit, Bilibinwang), Talisay (Poblacion 1, Poblacion 2, Poblacion 3, Poblacion 5) and San Nicolas (Poblacion), new fissures were observed in Sambal Ibaba, Lemery. Drying up of portions of Pansipit River has also been observed. Furthermore, newly acquired satellite images would show that the Main Crater Lake (MCL) has been drained and new vent craters have been formed inside the Main Crater and on the north flank of the volcano.

The latest update:

“Taal Volcano’s activity in the last eight (8) hours has been generally characterized by weak emission of steam-laden plumes 800 meters high from the Main Crater that drifted to the general southwest. A total of nine (9) discrete weak explosions were recorded by the Taal Volcano Network.

No additional fissures were mapped and reported. Existing ones are in the identified barangays of Lemery, Agoncillo, Talisay, and San Nicolas in Batangas Province as indicated in the January 15, 2020 5:00 PM update. Receding of Taal Lake water has been observed in Talisay, Laurel, Alitagtag and Lemery in Batangas Province.

The Philippine Seismic Network plotted a total of five hundred ninety-five (595) volcanic earthquakes since 1:00 PM, January 12, 2020. One hundred seventy-six (176) of these were felt with intensities ranging from Intensity I to V. Since 5:00 AM to 3:00 PM today, there were thirty (30) volcanic earthquakes plotted, including one (1) earthquake which was felt at Intensity I. This signifies continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity.



Alert Level 4 still remains in effect over Taal Volcano. This means that hazardous explosive eruption is possible within hours to days. DOST-PHIVOLCS strongly reiterates total evacuation of Taal Volcano Island and high-risk areas as identified in the hazard maps within the 14-km radius from Taal Main Crater and along the Pansipit River Valley where fissuring has been observed. Residents around Taal Volcano are advised to guard against the effects of heavy and prolonged ashfall. Civil aviation authorities must advise pilots to avoid the airspace around Taal Volcano as airborne ash and ballistic fragments from the eruption column pose hazards to aircraft. DOST-PHIVOLCS is continually monitoring the eruption and will update all stakeholders of further developments.”

So now Taal lake water is receding but the volcano is calming down is this the calm before the storm?

If this volcano does erupt would it be akin to the Icelandic one a few years ago or would it be another Krakatoa.
The Icelandic one was different as it’s location ironically was near to the air lanes to America so caused the maximum amount of disruption. Taal is a nasty one in the 1700’s an eruption from it caused 1000+ fatalities. So, I would guess that internationally there will not be as much disruption but St. Greta will not be impressed by the emissions into the atmosphere.

The latest update as of 0800L:

“Activity in the Main Crater in the past 24 hours has been characterized by steady steam emission and infrequent weak explosions that generated dark gray ash plumes 100 to 800 meters tall and dispersed ash southwest to west of the Main Crater.



Existing fissures identified in barangays of Lemery, Agoncillo, Talisay, and San Nicolas in Batangas Province have been observed to widen by a few centimeters. A steaming fissure has been newly observed on the northern slopes of Taal Volcano Island. Receding of the shoreline has been observed around the whole of Taal Lake.



The Philippine Seismic Network plotted a total of six hundred thirty-four (634) volcanic earthquakes since 1:00 PM, January 12, 2020. One hundred seventy-four (174) of these registered at magnitudes M1.2 – M4.1 and were felt at Intensities I – V. Since 5:00 AM on January 16, 2020 until 5:00 AM today, there were sixty-five (65) volcanic earthquakes plotted, two (2) of these registered at magnitudes M1.3 -M3.1 and were both felt at Intensity I. The Taal Volcano Network recorded nine hundred forty-four (944) volcanic earthquakes including twenty-nine (29) low-frequency earthquakes. Such intense seismic activity likely signifies continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity.

So overall no change it seems to be calming down.

Morning update:


Activity in the Main Crater in the past 24 hours has been characterized by steady steam emission and infrequent weak explosions that generated white to dirty white ash plumes 50 to 600 meters tall and dispersed ash southwest of the Main Crater.

Sulfur dioxide (SO2) emission was measured at an average of 360 tonnes/day yesterday, consistent with weak plume activity at the Main Crater.

The Philippine Seismic Network plotted a total of six hundred sixty-six (666) volcanic earthquakes since 1:00 PM, January 12, 2020. One hundred seventy-four (174) of these registered at magnitudes M1.2 – M4.1 and were felt at Intensities I – V. Since 5:00 AM on January 17, 2020 until 5:00 AM today, there were thirty-two (32) volcanic earthquakes plotted, registered at magnitudes M1.5 -M3.3. The Taal Volcano Network recorded eight hundred seventy-six (876) volcanic earthquakes including six (6) tremor events and twenty (20) low-frequency earthquakes. Such intense seismic activity likely signifies continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity.
