Earthquake

This earthquake occurred with a moment magnitude of 7.8 in a region which is characterized as having a weak seismic coupling.{{citation|title=The Seismogenic Zone of Subduction Thrust Faults|chapter=Anomalous Earthquake Ruptures at Shallow Depths on Subduction Zone Megathrusts|chapter-url=http://www.es.ucsc.edu/~thorne/TL.pdfs/LB_megathrust_SEIZE.pdf|first1=T.|last1=Lay|authorlink1=Thorne Lay|first2=S.|last2=Bilek|year=2012|publisher=Columbia University Press|pages=488, 489}} Earthquakes with slow rupture velocities are the most efficient tsunami generators, and this earthquake was classified as a tsunami earthquake.{{citation|title=Shallow subduction zone earthquakes and their tsunamigenic potential|first1=J.|last1=Polet|first2=H.|last2=Kanamori|authorlink2=Hiroo Kanamori|year=2000|journal=Geophysical Journal International|volume=142|issue=3|pages=684, 685|doi=10.1046/j.1365-246x.2000.00205.x|bibcode=2000GeoJI.142..684P|doi-access=free}}

Tsunami

The tsunami reached Java and Bali, with runups up to {{convert|14|m|abbr=on}} on the east Java coast and up to {{convert|5|m|abbr=on}} on the southwestern Bali coast. More than 200 people were killed in the tsunami.{{cite web | url=http://www.ess.washington.edu/tsunami/specialized/events/eastjava/eastjava.html | title=Tsunamis – past and present | access-date=2010-08-24 | archive-date=2013-06-01 | archive-url=https://web.archive.org/web/20130601173310/http://www.ess.washington.edu/tsunami/specialized/events/eastjava/eastjava.html | url-status=dead }} The shock could be felt strongly across Bali, central and eastern Java, Lombok, and Sumbawa.{{Cite web |url=https://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1994.php |title=Significant Earthquakes of the World |access-date=2017-08-28 |archive-url=https://web.archive.org/web/20110714105610/http://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1994.php |archive-date=2011-07-14 |url-status=dead }}
