Scientists have mapped one of the most hazardous spots on the globe in unprecedented detail: a 600-mile geologic boundary just off the #PacificNorthwest coast.
Along this fraught stretch, called the #CascadiaSubductionZone, 2 pieces of the #Earth’s crust slide against each other, building up stresses capable of unleashing a catastrophic 9.0-magnitude #earthquake & generating a #tsunami, w/waves as high as 40 feet.
…The entire area, which stretches from Northern #California to #Vancouver Island, is at risk. But the scientists found the geometry of the fault off the coast of #Washington, where the fault is flat & smooth, closer to the surface & extends farther onshore, may be particularly at risk.
…This #FaultZone is hazardous because it’s a “megathrust” #fault. One piece of the #Earth’s crust, a tectonic plate called the Juan de Fuca plate, dives down beneath the North American continental plate.
@trinux The name/address of the terrorism suspect was actually given to police by Apple, not Proton. The terror suspect added their real-life Apple email as an optional recovery address in Proton Mail. Proton can't decrypt data, but in terror cases Swiss courts can obtain recovery email.
A rescue ship and a warship were dispatched to help move thousands from neighbouring #TagulandangIsland north to #SiauIsland because of a warning about parts of the volcano falling into the sea potentially causing a #tsunami. #MountRuang#RuangVolcano
Potential tsunami risk after major eruption at Ruang volcano, Indonesia
Indonesia’s Ruang volcano in North Sulawesi experienced several violent eruptions on April 16 and 17, 2024, forcing authorities to raise the Alert Level to 4 of 4 and warn nearby residents there is a potential of a tsunami if parts of the volcano collapse into the sea, similarly to what happened in 1871. The last eruptive episode at this volcano was in September 2002 (VEI 4). #volcano#tsunami https://watchers.news/2024/04/18/potential-tsunami-risk-after-major-eruption-at-ruang-volcano-indonesia/
@ai6yr Well here's what happened in 1871 but, it doesn't say how far out the tsunami went.
The 1871 Ruang eruption began on March 3, and ended on March 14 at the Ruang volcano in the Molucca Sea, Indonesia. The eruption triggered a locally devastating tsunami measuring 25 m (82 ft). It flooded many villages on nearby islands, killing some 400 people. https://en.wikipedia.org/wiki/1871_Ruang_eruption_and_tsunami
#MountRuang, located in in North #Sulawesi Province, first erupted at 9:45pm (13:45 GMT) on Tuesday sending billowing clouds of smoke and ash high into the sky.
Officials worry that part of the #volcano could collapse into the sea and cause a #tsunami as it did during a previous eruption in 1871 (#Krakatoa).
