Earthquakes update

West Coast quake warning system now operational, with limits

Blog note: And great earthquakes shall be in diverse places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven. (Luke 21:11). Jesus is giving a series of prophecies about what to look for as the age of grace comes to a close. This verse from Luke is one of many such prophecies from throughout the Bible. 2017 was the worst year in recorded history for the intensity, frequency, severity, duration and occurrence of a large number of severe natural disasters worldwide. Earthquakes, volcanoes, hurricanes, typhoons, cyclones, torrential flooding, unprecedented wildfires in unusual places, devastating droughts, excessive/scorching heat setting records everywhere, record snowfalls in Europe and Russia. Snow in the Arabia. This list can go on. Most studied eschatologists believe these ‘fearful sights’ and massive natural disasters are all part of the ‘CONVERGENCE’ of signs that this Biblical and prophetic age is closing. Most people who study prophecy are familiar with the routine reference(s) made that these things will be like a woman having labor pains that occur in greater severity, frequency, size and duration prior to giving birth. End of note.

West Coast quake warning system now operational, with limits

Associated Press. October 17, 2018.

PASADENA, Calif. (AP) — Automated alerts from the fledgling West Coast earthquake early warning system are ready to be used broadly by businesses, utilities, schools and other entities but not for mass public notification, officials said Wednesday.

“We’re making a large change from a production prototype in pilot mode to an open-for-business operational mode,” Doug Given, earthquake early warning coordinator for the U.S. Geological Survey, told a press conference at the California Institute of Technology.

The system being built for California, Oregon and Washington detects that an earthquake is occurring, quickly analyzes the data and sends out alerts that may give warnings of several seconds to a minute before strong shaking arrives at locations away from the epicenter.

That can be enough time to automatically slow trains, stop industrial processes, start backup generators, pause a surgery or send students scrambling for protection under desks and table.

Pilot programs involving select users have been underway for several years.

“The system is not yet finished, it’s not complete, there is a lot of work to be done, however there is a lot of capability in the system as it exists today to the point it can definitely be used,” Given said.

The sensor network is about 50 percent complete and funding has been secured to complete it in California in the next two years and get two-thirds of the way built out in the Pacific Northwest, he said. Another key development occurred Sept. 28 when a new generation of ShakeAlert software was deployed.

Given said among its important improvements is reduction of false and missed alerts. False alerts typically have occurred when a large quake elsewhere in the world is detected by a sensor and is mistaken for a local temblor. “The system performs now much better than it did in the past to the point where it is much more reliable,” he said.

Officials now want to open ShakeAlert to a wide array of applications and are encouraging potential users to contact the USGS.mThat doesn’t yet include mass public notifications for several reasons, including the fact that current cellphone technology is too slow for timely delivery of notifications.

“Most folks expect to get the alerts on their phone and that is of course is the preferred way that we’d like to get it into everybody’s hands,” Given said. “Unfortunately the technology that is built into your phone to send you notifications was not designed with earthquake early warning in mind.” Rep. Adam Schiff, D-Calif., who has championed funding of the system, said it will also be important to make sure people know what the alerts mean, what to do when they get them, what not to do and to understand there may be false alarms.

“The education component is going to be very, very important, but this is a wonderful milestone,” he said. “We can now see the end, I hope, in two or three years where the system is fully built out and funded and in operation.”
