Mag. 7 Indonesia Earthquake - 5th August 2018

[StevieTNZ]

Thirty nine people have died after a powerful earthquake rocked the Indonesian tourist islands of Lombok and neighbouring Bali, triggering a tsunami warning just a week after another quake in the same region killed 16 people.

The magnitude seven earthquake hit about 6.46pm Jakarta time (11.46pm NZ) on Sunday, 27 kilometres north-east of northern Lombok in Indonesia at a 15-kilometre depth.

Oh wow, our Minister of Justice, was in his hotel room on the island when it happened - https://www.stuff.co.nz/world/asia/...e-caught-up-in-pretty-terrifying-lombok-quake

That's first M7 event since Feb 2018

The USGS have down graded it to 6.9

The count for M7.0 - 7.9 events this year is well down on the long term averages.
By now there should have been around 10 - 12 in that range there have been only 5 and they were all back in Jan and Feb.
18 / year is the long term avg.

M6.0 - 6.9 events are also well down compared to the averages. So far 49 for the year.
The annual avg is around 130

So far there hasn't been the M8+ event for the year either

I just got back last week from Bali. I've been messaging a lot of friends I made over there.

The aftershocks continue on Lombok Island.
As I am typing this the latest respectable ( and largest, so far) aftershock is tailing off.

M 5.9, 3km SE of Todo, Indonesia
2018-08-09 05:25:31 (UTC), 10.0 km deep

The red dot on the map

This is about 40km WSW of the M6.9 main shock

I have taken the USGS base map and added the event magnitudes to it...

apologies for the low quality image
the forum does a lot of compression

Stuff must have updated the article to 5.9.

And again:

Lombok in Indonesia has been hit by another series of earthquakes - including a major 6.9 magnitude quake - which left one person dead and caused others to run out into the streets in panic.

The latest tremors arrived two weeks after a 7.0-magnitude earthquake killed 460 people on the island and caused damage worth more than 5 trillion rupiah (£268 million).
