Potential Earthquakes above Magnitudo 7 and Tsunami up to 29 meters on the south coast of East Java, Indonesia

 Meteorology, Climatology and Geophysics Agency (BMKG)

warns of potential earthquakes above Magnitude 7 and
tsunami up to 29 meters on the south coast of East Java. Head of BMKG Dwikorita Karnawati said that the results
BMKG analysis, the entire coast of East Java has the potential to be hit
tsunami if there is a big earthquake." The results of our analysis for the East Java region, the entire coast pesisir
its potential, the maximum height is 26-29 meters in the Regency
Trenggalek, that's the maximum height. Fastest arrival time 20-24
minutes in Blitar Regency," he said in a webinar on the channel
Youtube InfoBMKG. However, the results of the BMKG analysis and study also state that:
that the potential for inundation resulting from the tsunami could reach
22 meters high."This has entered the puddle, not the height of the waves on the edge
the beach. The inundation can reach 22 meters, this is until the entry
also protrudes quite far [inland]," he said.
In addition to revealing the potential for a tsunami in East Java, he also
explains the increase in the frequency of small earthquakes since the beginning
years and the so-called seismic gap still stores energy. BMKG has observed and analyzed earthquake phenomena
increasing number of earth in East Java in recent times. From the results of the analysis, East Java has increased the number of
small earthquakes.
"Since the beginning of the year we surveyed. Starting from previous years
the average earthquake is 300-400 times, but since January it has jumped
600 times more and indeed the average is 600 times today, in East Java
there was a jump," Dwikorita said in a webinar on the channel
Youtube infoBMKG, Friday (28/5).
He explained that his party had been along the coast from East Java
until the Sunda Strait to check what you're worried about
potential for earthquakes with a magnitude above 7.
reveal this 8.7 potential and worst-case scenario [magnitude]
can generate a tsunami.

Dwikorita explained that frequent small earthquakes
rocking East Java is an alarm for all parties.
Although there were no major earthquakes, he mentioned an increasing trend
earthquakes with a small strength in it usually initiate
big earthquakes.
"In the south of East Java, of the hundreds of earthquakes since 2008,
there seems to be an empty zone, there are no central dots
the earthquake. These empty zones from said
as a seismic gap that is worrying," he said.
