Cluster of earthquakes in Chiayi County overnight - nothing big, but very shallow - one as shallow as 5km.
I’m nervous now when i see cluster activity coz that’s what happened here. Whereas ‘our’ fault line should only be capable of small to mid-size quakes, that’s not the case in Chiayi, which is very much prone to a big one
I’ve got no idea. You’d have to ask an expert, but most of them are either too scared to say anything in case they are wrong or busy writing pointless academic papers to insure they keep getting funded.
I do know that there is an interconnecting web of fault lines and it would seem reasonable that the recent burst of activity was associated with the Chi Chi fault line in some way
On the other hand, cluster earthquake activity is a common phenomenon in Hualien and hasn’t escalated to a major earthquake there in recent times.
The ‘funny’ thing about earthquakes is that in themselves, they are actually pretty much harmless - it’s the man-made structures that fall down that cause all the death and destruction (ok, tsunamis and landslides are the exceptions)
Another pair of earthquakes overnight in virtually the same place as the previous night’s trio in Chiayi - and probably more that didn’t register with CWB. I’d be getting pretty jittery if i lived in that area
We are close to the full moon at the moment - there is an unproven theory that earthquakes can be triggered by the tides
In the afternoon there was a 4.8 in the mountains between hualien and yilan. Felt a bit of shaking on the bed, it was the first eartquake I felt in quite a long time.
Yesterday was the anniversary of the Tainan quake. Among the saddest things so far: when the building toppled over, seven kids became orphans, six were left with only one parent.
This one was pretty scary, felt the same way as last year but apparently 2016’s was slightly stronger. Thanks God no injury reported. Heard ambulances ten minutes later which got us nervous but glad no one was killed or injured this time.
CWB measured the main quake at 5.6. Several shallow aftershocks. Tainan residents are no doubt feeling pretty jittery given last year’s big quake.
Hope that was the worst of it…
Also noticed there was a small quake in Hsinchu recently at a depth of only 1.5km. That’s the shallowest quake I’ve ever heard of. God help us if there was a big one at that depth
Seems like it has quietened down there now S, so that’s good.
Were there any fore-shocks, or it just came out of the blue? How long did it last? Was it stuff flying off shelves level?
Reports say four people admitted to hospital with minor injuries so looks like it was just under the threshold of major destruction - let’s hope it stays that way
Something i don’t quite understand. It was measured as a 5.6, but CWB reports the ‘local largest intensity’ as 6 for Tainan City. Anybody know how that works?
Is it like the weather with the actual temp and the apparent temp?
Wow, 15 minutes later and I’m the first to post? We’re getting slow. In Danshui, this one was mild but seemed to last forever. 5.7 magnitude, 64.1km NNW of Taitung County, May 16 at 7:12am.
