I am the Man From Minto© ™ ® - A Prospector Who Knows His Rocks And Stuff© ™ ® The 2010 Mount Meager landslide was a large catastrophic debris avalanche that flowed to the south, into the Lillooet Valley British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7). More than 45,000,000 m3 (1.6×109 cu ft) of debris slid down Mount Meager, temporarily blocking Meager Creek and destroying local bridges, roads and equipment. It was one of the largest landslides in Canadian history and one of over 20 landslides to have occurred from the Mount Meager massif in the last 10,000 years. Although voluminous, there were no fatalities caused by the event due in part to its remote and uninhabited location. The landslide was large enough to send seismic waves more than 2,000 km (1,200 mi) away into the neighboring U.S. states of Alaska and Washington and beyond. Multiple factors led to the slide: Mount Meager's weak slopes have left it in a constant state of instability. The massif has been a source of large volcanic debris flows for the last 8,000 years, many of which have reached several tens of kilometres downstream in the Lillooet River valley., to the south. It is arguably the most unstable mountain massif in Canada and may also be its most active landslide area. And on the north side lies Downton Lake Hydro Reservoir, impounded by the La Joi Dam, the uppermost of the Bridge River Project dams. The earliest identified Holocene landslide was in 7900 BP (before the present, or read it as the number of years ago). Further landslides occurred in 6250 BP, 5250 BP, 4400 BP, 2600 BP, 2400 BP, 2240. BP BP, 2170 BP, 1920 BP, 1860 BP, 870 BP, 800 BP, 630 BP, 370 BP, 210 BP, 150 BP and in 1931, 1947, 1972, 1975, 1984, 1986 and 1998. These events were attributed to structurally weak volcanic rocks, glacial unloading, recent explosive volcanism and glacial activity. Those who dance with earthquakes and volcanoes are considered mad by those who cannot smell the sulfur.

(EAS) - Emergency Alert System - A Drill for Cascadia Subduction Zone EAS - Scenario #1* In the US

THIS IS A DRILL based on current scientific understanding. Can we get
serious now?

My first attempt at an EAS* video. Comment down below what you liked, and what you think I should do differently next time. This EAS scenario is
about what would happen if the Cascadia Subduction Zone off the coast
of the Pacific Northwest experienced a major earthquake. Later on, I
may upload a version of this video with sirens. This video contains
fully valid EAS tones. I am not responsible for EAS activations,
accidental or intentional, that may result of this video. If you're
going to use this as part of a prank, I strongly advise you to only
use it on your friends, family, or people you know. Walking into a
public park with a speaker and this playing on full blast is STRONGLY
DISCOURAGED.

* In the US
Emergency Alert System (EAS) is a national warning system in the United States put into place on January 1, 1997 (approved by Federal Communications Commission
(FCC) in November 1994),[1]when it replaced the Emergency Broadcast System
(EBS), which in turn replaced the CONELRAD System. The official EAS is designed to enable the President of the United States to speak to the United States within 10 minutes.[2]
In addition to this requirement, the EAS is also designed to alert the public of local weather emergencies such as tornadoes and flash floods (and in some cases severe thunderstorms depending on the severity of the storm).

The EAS is jointly coordinated by the Federal Emergency Management Agency
(FEMA), the Federal Communications Commission (FCC) and the National
Oceanic and Atmospheric Administration (NOAA). The EAS regulations and standards are governed by the Public Safety and Homeland Security Bureau of the FCC.
Authorized organizations are able to disseminate and coordinate emergency alerts and warning messages through EAS and other public systems by means of
IPAWS.[3] EAS messages are transmitted primarily via terrestrial and satellite
radio and television (including broadcast and multichannel television),
which are required to participate in the system.[4]
Wireless Emergency Alerts are a secondary system using Cell Broadcast
to relay public alerts to cellphones.
