[ed: The speed of light is 670,616,629 mph, so close to that.] These cause most of the damage associated with earthquakes. If you have a long straight piece of fault (at least 62 miles (100 kilometers) long), the earthquake has time to build up to a much faster speed than it might if the fault curved.One region for prime development of these supershear quakes is a portion of Calfornia's San Andreas fault that extends from a point several miles southeast of San Francisco in a northwest direction for hundreds of miles along the coast. S-waves travel more slowly, usually at 2.5-4 km/sec (9,000-14,000 km/h). at a speed of about 2.7 km/sec or 5,800 mi/hr.

Evaluating the data from these earthquake substations allows students to track how an earthquake travels through the crust and measure how fast the seismic waves travel.
In addition to the rotational speed of the Earth spinning on its axis, the planet is also speeding at about 66,660 miles per hour (107,278.87 km/h) in its revolution around the sun once every 365.2425 days. How Fast Does the Earth Travel While Orbiting the Sun?

Earthquake faults may rupture faster than previously thought, seismologists say, possibly meaning more potential destruction in certain quake-prone zones.The rupture speed of most earthquakes tops out around 5,600 to 6,700 mph (9,000 to 10,800 kilometers per hour) which is slower than the speed at which seismic shear waves (one type of seismic wave generated by an earthquake) emanate from the epicenter of the quake.But there can be situations where the earthquake ruptures faster, up to 11,000 to 13,000 mph (18,000 or 21,600 kilometers per hour), and sends out a shock wave that can do more damage than a normal earthquake. This concentrated cone of waves can amplify the quake's destructive power.âIt's like a sonic boom in an earthquake,â says While it's not yet possible to say for sure if the supershear speed intensified the Indonesia quake's landslides, liquefaction, or tsunami, the pair of new studies does offer a rare look at this little-understood and potentially deadly phenomenon.âWe have observed only a handful of supershear earthquakes, and even fewer with this level of detail,â says seismologist Jean-Paul Ampuero of the Université Côte d'Azur in France, a coauthor of one of the studies.âThis is going to tell us something fundamental about the way the Earth works,â says Bohon, who was not involved in either study.

Currents of mud swallowed anything in their paths, sweeping away entire sections of the city of Palu and crosscutting the region's neat patchwork of crop fields. Kids conduct a cool refraction experiment in materials like water and air for this science fair project. They occur when stress at a plate or other regions on the earth is released.

This corresponds to nearly 18,000 miles per hour … Learn about the geophysics behind earthquakes, how they are measured, and where the most powerful earthquake ever witnessed occurred. Science
Roads were offset; buildings seemingly cut in two.âThis is definitely huge for a [magnitude] 7.5 earthquake,â Socquet says. In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates. breaking windows of the station, he understood that These commonly zoom by around 11,200 miles an hour. The primary waves are the first waves to arrive at a location. Seismic waves travel at variable speeds, up to maybe 8 km per second in the crust or 13 km/s in the mantle.
