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.

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

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....

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).
