    Earthquake
In summary, on August 5th, 2018, a magnitude 7 earthquake struck the island of Lombok in Indonesia, causing widespread damage and claiming the lives of over 500 people. The powerful quake, with its epicenter located in the northern part of the island, also triggered landslides and a tsunami warning. Many buildings, including homes, hotels, and schools, collapsed or were severely damaged, leaving thousands of people homeless. The Indonesian government declared a state of emergency and launched a massive relief and recovery effort to assist those affected by the disaster. The earthquake serves as a reminder of the region's vulnerability to seismic activity and the importance of disaster preparedness.

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 eitherfrom my seismograph

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).
