Seismic activity is slowly moving towards the southern part of La Palma. This is where a giant landslide could trigger a devastating tsunami.
Within the last 2 days, more than 115 earthquakes have been located in the southern area of the island of La Palma. Twelve of them were felt by the population and even four reaching an intensity III-IV in the epicentral zones. The largest earthquake, a M3.7, occurred at 19:14 UTC yesterday evening.
Something big is brewing! This guy even suggests a new volcano could soon start erupting on the southern part of the island… Terrifying, no?
As in previous days, the depths of the hypocenters are between 10-15 km with the exception of 6 earthquakes that hit at greater depths (30-36 km). This new swarm rattles the same area as the seismic series in 2017, 2018 and 2020.
The mean amplitude of the volcanic tremor has presented has presented different pulses in the last two days, coinciding with the moments in which the activity on the surface intensified.
The column height measured at 5:30 UTC is 4,500 m, a similar value on the previous days.
The Cumbre Vieja volcano on the Spanish island of La Palma is now erupting even more aggressively after weeks of gushing lava, Spain’s Instituto Geográfico Nacional (IGN) said Sunday.
Lava from the La Palma volcano has reportedly increased the size of the island on the western shore by 30 hectares. Streams of lava have been spilling into the Atlantic Ocean following the eruption.
The volcano’s activity “continues to be intense” and a new crater was discovered Saturday, the Canary Islands government and IGN said in a joint statement.
I think I read about the salt water taffy when I read Simon Winchester’s book on Krakatoa. See link to summary below. The summary speaks of water effects in France, so NJ is not an impossibility. One article says that Atlantic City had a major storm on August 30, 1883 which flooded a man’s boardwalk shop filled with taffy which he rinsed and then sold as Salt Water Taffy. Krakatoa had massive eruptions on August 26 and 27, 1883, so it is not impossible that with a storm and 2 or 3 feet of dissipated tsunami rise, that the storm could have had a higher than normal rise, and the board work is very close to the water.

The Wiki article titled “The 1883 Eruption of Krakatoa” has the following quote and reference 15 has an interesting link on a number of major effects: “Smaller waves were recorded on tidal gauges as far away as the English Channel.[14] These occurred too soon to be remnants of the initial tsunamis and may have been caused by concussive air waves from the eruption. These air waves circled the globe several times and were still detectable on barographs five days later.[15]”

I meant to send you my Comment #101, above.
Got it. Thanks.
Salt water taffy... great, now I want some.

Oh that’s a lot of bunkum. Krakatoa eruption was a minor volcanic eruption, that too many people go on about. Waves in the Atlantic could have been caused by a host of other events and pining them on Krakatoa is just dumb.
The Mount Pinatubo in the Philippines on June 15, 1991 was also a VEI 6 event, accompanied by a 7.8 mag quake. In other words it was as big as Krakatoa and possibility bigger. No East Coast waves battered and flooded any Boardwalk shops.
The 1815 Tambora eruption was 100 times larger than Krakatoa. According to the bunkum, that eruption should have drowned the entire world. It didn’t.
Like flushing a crapper
The height would shrink and spread out, but it would build back up after hitting the shore. It might be one inch high but miles wide.
Would a broad continental shelf reduce it in size?
Wow!
Here in central Indiana, all I worry about are tornadoes (no sharks, please), OSU football, and the New Madrid fault letting go again.
Where's the link?
I think landslide induced Tsunamis are devastating locally but do not translate into cross ocean events.
Folks can get the latest there.
All I can say about the New Madrid is that if, God forbid, it cuts loose, the country better get Trump back. STAT.
I can understand how a mass of dirt and rocks sliding into the ocean cause waves; but it escapes me how dirt and rocks already underwater and sliding down further can make many waves except locally.
The first will RAISE the water level, the second will not.
