What weapon would cause a 2.6 magnitude earthquake?
Hitting an ammo dump will do that.
That was an ammo dump and a very large one based on the video. I would guess that Israel decided to destroy the rockets intended for them in one spot vs rely on the Iron Dome.
How or why some of our fellow FReepers will have a problem with this is beyond me. Iran uses Syria to strike at Israel..... as long as they do this in my opinion Israel has a right to defend themselves, but some will be along here shortly to tell us that Israel has “no right to attach a sovereign nation.” Syria is no longer a sovereign nation - it is a puppet state used for the goals of others. If my neighbor allowed someone who wants me destroyed to stockpile mortar shells and tubes on their property intended to strike me should I simply watch them and deal with the shelling later?
Secondary explosions from the massed stockpile they hit.
To my knowledge, only a bunker buster missile or bomb that set off a large secondary store of munitions.
I don't want to think about anything else.
It wasn't the weapon that caused the earthquake. The 'earthquake' came several minutes later as the AMMO DUMP exploded.
This is an example of poor reporting, I think.
It is possible that the explosion registered a “spike” of 2.6 on one or more seismographs located close to where the bomb struck. However, a single instantaneous localized spike is not the same thing as an earthquake.
The same ordnance used against the Lebanese terrorist bunkers filled with Iranian missiles will probably have the same effect — we’ll know soon enough.
MOAB first and then the internal munitions going off
Boom
Then BOOM!
Find the video of a MOAB drop in Afghanistan against just such a position on YT
What weapon?
That depends a lot on what was inside the target.
Quake sounds like a secondary explosion.
Better question- What stored ordnance exploded by a tactical missile or bomb would cause a 2.6 reading on seismic sensors?
Or, which seismic detectors (how close to impact location) provided the readings being reported?
