Earthquake Activity Ramps Up at Puerto Rico Subduction Zone
A significant escalation is occurring at the Puerto Rico Subduction Zone. A swarm of quakes continue with close to one hundred quakes in just the last three days. What is most alarming is the increase in magnitudes. When a swarm starts to hit a series of high 3's and into 4's magnitude, it trips a geological/seismological switch often elevating an 'observation' into a 'watch'. (see EQ link below)

Cumbre Vieja Volcano -- Potential collapse and tsunami at
La Palma, Canary Islands
Abstract. Geological evidence suggests that during a future eruption, Cumbre Vieja Volcano on the Island of La Palma may experience a catastrophic failure of its west flank, dropping 150 to 500 km3 of rock into the sea. Using a geologically reasonable estimate of landslide motion, we model tsunami waves produced by such a collapse. Waves generated by the run-out of a 500 km3 (150 km3) slide block at 100 m/s could transit the entire Atlantic Basin and arrive on the coasts of the Americas with 10-25 m (3-8 m) height.
