Faultlines surface, B'luru prone to quakes

BENGALURU: Bengaluru area isn't secure from earthquakes. Arkavati plate, on which town and surrounding districts sit, has advanced energetic faults, leaving the area at the chance of earthquakes. Such quakes will likely be of very low magnitude.

Ramesh Dikpal, a scientist in the earthquake department of Karnataka State Natural Disaster Monitoring Centre (KSNDMC), instructed NewsTread the improvement of faults through the Arkavati plate has been showed through an research of latest seismic hazard map from the Bureau of Indian Standards.

“Our centre with 14 stations has been monitoring seismic actions in Karnataka prior to now decade. Recordings in Bengaluru and surrounding districts come from the observatory at Tippagondanahalli dam web page. Every few months, we pay attention anecdotes of micro-tremors. The newest seismic job recorded was once at Channapatna in 2017, and at Kanakapura in 2014. Both have been of a very low magnitude. There was once no damage at all,” he added.

Chitradurga recorded seven quakes in 2013

Scientist Ramesh Dikpal stated Hosadurga belt of Chitradurga has also advanced faultlines, resulting in low-magnitude quakes over the last few years. “On November 13, 2018, a 1.6-magnitude quake was once recorded at our Chitradurga observatory. In 2013, Chitradurga recorded seven quakes, and one with 2.5 magnitude had its epicentre at Sigehatti village,” he added.

KSNDMC mavens stated the seismic hazard map of India puts Karnataka in Zone II (least energetic) and Zone III (moderate). “Coastal and northern-interior districts bordering Maharashtra are in Zone III, and the remaining, including Bengaluru, lie in Zone II. In the new studies, a number of energetic faults had been recognized in Chitradurga, Bhatkal, Udupi and Bengaluru area. Much of the seismic job in Karnataka has been in the south, particularly in the Bengaluru-Mysuru area, in the recent years. Historically, tremors have passed off in lots of different parts of the state akin to Ballari,” knowledgeable stated.

KSNDMC director GS Srinivasa Reddy stated geological actions are on the rise in several parts of the sector. “Proximity to faults does now not translate into a better hazard. Damage from earthquakes depends on numerous factors — subsurface geology and adherence to the development codes,” Reddy added.

August tremors in Bengaluru due to quarry effect?

Tremors that created panic in RR Nagar, Kengeri and neighbouring spaces of Bengaluru in August 2018 might be due to blasting at stone quarries. KSNDMC scientists stated their observatory at TG Halli didn’t document any tremors at that time. In April 2017, citizens of RR Nagar, Kengeri and Bannerghatta Road had experienced identical tremors, spreading panic.
