How does Dost and Phivolcs predict and measure the strength of an earthquake?

Data is sent to the PHIVOLCS Data Receiving Center (DRC) to determine earthquake parameters such as magnitude, depth of focus and epicenter. Together with reported felt intensities in the area (if any), earthquake information is released once these data are determined.

Did Japan have a warning before the tsunami?

Before March 11, 2011, Japan had already developed sophisticated high-technology tsunami-warning systems that included satellite communications and hundreds of real-time monitoring stations. But on March 11 the community-level response (and community-based warnings) was the key that saved countless human lives.

Is a 4.5 earthquake strong?

Richter magnitudes. . … Events with magnitudes greater than 4.5 are strong enough to be recorded by a seismograph anywhere in the world, so long as its sensors are not located in the earthquake’s shadow. The following describes the typical effects of earthquakes of various magnitudes near the epicenter.
