How can you tell the difference between an explosion and an earthquake on a seismogram?

How can you tell the difference between an explosion and an earthquake on a seismogram? The differences in the depth and extent of the energy source produces differences in the waveforms that are recorded on a seismogram.

How do you differentiate explosion from implosion Do they have similar impact?

In an explosion (top), force radiates away from a source. With implosion (bottom), the object collapses upon itself (generally being crushed by an outside force).

What is the atomic bomb equivalent to a 7.0 earthquake USGS?

What is the atomic bomb equivalent of energy released during a 7.0 quake? An 8.0 quake? A 9.0 quake? A 7.0 is 199,000 tons, 8.0 is 6,270,000 tons, and a 9.0 is 99,000,000 tons.

What is a explosion earthquake?

Explosion earthquakes are directly related to volcanic events, and they occur with volcanic explosions—namely, Strombolian and Vesuvian. Each explosion produces an earthquake; a seismic record is commonly accompanied by an acoustic signal. Explosion earthquakes occur just beneath the crater floor.

What’s the difference between explosion and detonation?

Discovered in 1881 by French scientists, detonation is the result of a supersonic wave initiating a secondary explosion. Explosion, on the other hand, is a general term for an accelerated release of energy generating extreme temperatures, releasing of gases and expanding volume.

Can a nuke cause a tsunami?

It was expected to cause massive damage to coastal cities or coastal defences. The tests revealed that a single explosion would not produce a tsunami, but concluded that a line of 2,000,000 kg (4,400,000 lb) of explosives about 8 km (5.0 mi) off the coast could create a destructive wave.

Do bombs explode or implode?

The core of an implosion-type atomic bomb consists of a sphere or a series of concentric shells of fissionable material surrounded by a jacket of high explosives, which, being simultaneously detonated, implode the fissionable material under enormous pressures into a denser mass that immediately achieves criticality.

What should you never do in an earthquake?

What not to do in an earthquake

• Do not run outside. Do: Shelter in place using Drop, Cover and Hold On.
• Do not get in a doorway. Do: Shelter in place under a table. In modern houses and buildings, doorways are no safer, and they do not protect you from flying or falling objects.
• Do not make phone calls. Do: Text.

How deep was the earthquake that struck Taiwan on December 1 2008?

30 km
The epicentre of the quake, which struck at 0316 GMT, was 31 km (19.2 miles) northeast of Chenggong on the east coast, at a depth of 30 km, the Central Weather Bureau said in a statement.

Can a bomb create a tsunami?

The tests revealed that a single explosion would not produce a tsunami, but concluded that a line of 2,000,000 kg (4,400,000 lb) of explosives about 8 km (5.0 mi) off the coast could create a destructive wave.

What is the detonation velocity of C4 compared to TNT?

So I think that Kevin McNeill has given you the most conclusive answer, which is “TNT with a detonation velocity of 7300 m/s while C-4 (91\% RDX) ….. velocity of 8040 m/s.” What that means is that if you work in a quarry and want to blast rocks, you want a low speed detonation. Very slow Amphor or the likes would be your choice.

What is the difference between C4 and dynamite?

The real difference is in their sensitivity to heat, shock, and friction. C-4 is very insensitive while dynamite is relatively sensitive to all three. But as to your question both would produce very similar effects with C-4 edging out Nobel’s dynamite slightly.

How can you change the direction of the explosion of C4?

You can mold it into different shapes to change the direction of the explosion. The explosive material in C-4 is cyclotrimethylene-trinitramine (C3H6N6O6), commonly called RDX (which stands for “royal demolition explosive” or “research development explosive”).

What are the advantages and disadvantages of C4?

A major advantage of C4 is that it can easily be molded into any desired shape. C4 can be pressed into gaps, cracks, holes and voids in buildings, bridges, equipment or machinery. Similarly, it can easily be inserted into empty shaped charge cases of the type used by military engineers. C4 is very stable and insensitive to most physical shocks.
